SQLite before 3.53.2 contains a heap-based buffer overflow vulnerability in the FTS5 full-text search extension that allows attackers to cause a crash or execute arbitrary code by supplying a crafted database with malicious continuation page metadata specifying a szLeaf value smaller than 4. Attackers can trigger an integer underflow in fts5ChunkIterate() causing an inflated remaining byte count during FTS5 MATCH query processing, leading to a heap buffer overflow of attacker-controlled data in applications compiled with SQLITE_ENABLE_FTS5.

Multiple Vulnerabilities in SQLite

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1921 advisory.

    When undici parses a Set-Cookie header, it accepts any SameSite attribute value that contains Strict, Lax,     or None as a substring, rather than the case-insensitive exact match specified by RFC 6265. Non-spec     values are silently mapped to one of the three standard tokens:

    SameSite=NoneOfYourBusiness is parsed as None, the most permissive setting.SameSite=StrictLax is parsed as     Lax, a downgrade from Strict.Affected applications are those that consume Set-Cookie headers from server     responses (for example via undici's fetch or proxy code paths) and then forward or rely on the parsed     sameSite attribute. A malicious or non-compliant server can coerce the consumer's view of a cookie's     SameSite policy to a weaker value, silently degrading the SameSite enforcement the cookie is supposed to     provide.

    This was introduced in undici 5.15.0 when the cookies feature was added. (CVE-2026-11525)

    SQLite before 3.53.2 contains memory corruption vulnerabilities in the FTS5 full-text search extension     that allow attackers to cause process crashes, memory exhaustion, or arbitrary code execution by supplying     a crafted database with malformed FTS5 page data. Attackers can trigger an out-of-bounds read in     fts5LeafSeek() via an attacker-controlled loop bound and a heap buffer overflow write in     fts5ChunkIterate() through a crafted continuation page causing an integer underflow, exploitable when an     FTS5 MATCH query is executed against the malicious database. (CVE-2026-11822)

(CVE-2026-11824)

    The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message     but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many     small or empty continuation frames that each pass per-frame and cumulative-size validation, collectively     causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of     service.

    Affected applications are those using the undici WebSocket client (new WebSocket(...)) or the     WebSocketStream API that can be induced to connect to an attacker-controlled or compromised WebSocket     endpoint.

    All releases starting at undici 6.17.0 are affected. (CVE-2026-12151)

    A flaw in Node.js proxy tunnel error handling could expose proxy credentials in ERR_PROXY_TUNNEL error     messages.

    When proxy credentials are embedded in the proxy URL, they may be exposed through error handling paths and     captured by logs, diagnostics, or other error consumers.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48615)

    A flaw in Node.js Permission Model enforcement allows Bypass via `process.report.writeReport()` Path     Misvalidation. This can lead to confidentiality impact or bypass of the intended security boundary under     affected configurations. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js     24**, and **Node.js 26**. (CVE-2026-48617)

    A flaw in Node.js TLS hostname handling can cause Node.js unicode dot separator handling can lead to tls     wildcard-depth authentication bypass due to resolver and verifier hostname normalization mismat.

    This can lead to confidentiality impact or bypass of the intended security boundary under affected     configurations.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48618)

    A flaw in Node.js HTTP/2 client allows a server to send an unlimited number of ORIGIN frames, which could     lead to an Out of Memory error on the client.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48619)

    A inconsistency in Node.js hostname matching can cause a trust-policy bypass in multi-context mTLS setups.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48928)

    A flaw in Node.js TLS hostname handling can cause Embedded-nul hostnames can lead to silent authority     rebinding due to c-string truncation in resolver bindings.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48930)

    A flaw in Node.js HTTP Agent can cause a client to accept as valid a response that is send before the     client has sent the request.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48931)

    A flaw in Node.js WebCrypto implementation can crash the process if the input of subtle.encrypt() is a     multiple of 2GiB.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48933)

    A flaw in Node.js TLS host verification can cause an attacker to bypass certification validation.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48934)

    A flaw in Node.js Permission API can cause a file metadata to be modified even on a path that was set as     read-only with e.g. --allow-fs-read.

    This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
    (CVE-2026-48935)

    A flaw in Node.js HTTP/2 server API can cause servers to keep accepting data even after sending a `GOAWAY`     frame. This vulnerability affects two supported release lines: **Node.js 22** and **Node.js 24**.
    (CVE-2026-48937)

    Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets. An     attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after     a request completes. When the client dispatches the next request on that socket, it associates the     injected response with the new request, causing responses to be delivered to the wrong requests.

    This requires an attacker-controlled or compromised upstream HTTP/1.1 server and keep-alive connection     reuse. (CVE-2026-6733)

    undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded     sequences like %0D%0A, %00, %3B, and %3D into their literal byte equivalents. RFC 6265 SS5.4 does not     specify any decoding and browsers do not decode either.

    Applications that parse a Set-Cookie header and then forward the parsed value into a response header     (proxies, middleware, SSR frameworks) become vulnerable to HTTP response header injection: an attacker-     controlled upstream can inject arbitrary Set-Cookie, Location, or Cache-Control headers into the     application's downstream response, enabling session fixation, open redirect, or cache poisoning.

    Affected applications are those that use undici's cookie parsing (parseSetCookie, parseCookie,     getSetCookies) and forward the parsed cookie value into a response header.

    This was introduced in undici 7.0.0 (CVE-2026-9679)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    (CVE-2026-48619)

    sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.2.1, the     preAuthEncoding function in @sigstore/core uses Node.js ascii encoding when converting the PAE string to     bytes, allowing payloadType to be mutated after signing without invalidating the signature and breaking     the type-binding guarantee that DSSE is designed to provide. This issue is fixed in version 3.2.1.
    (CVE-2026-48758)

    sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 4.1.1, the     documented certificateOIDs option in sigstore.verify() is accepted by the public API but discarded before     verification, so required certificate extension OIDs are never checked and applications relying on     certificateOIDs to restrict which certificates may sign artifacts can accept unauthorized certificates.
    This issue is fixed in version 4.1.1. (CVE-2026-48815)

    sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 3.1.1,     @sigstore/verify derives a transparency-log timestamp from tlogEntries[].integratedTime for bundle v0.2     inclusionProof-only entries even though the inclusion proof path does not cryptographically bind     integratedTime, allowing an attacker who can supply an untrusted bundle to influence certificate validity     and timestampThreshold verification decisions. This issue is fixed in version 3.1.1. (CVE-2026-48816)

    Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets. An     attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after     a request completes. When the client dispatches the next request on that socket, it associates the     injected response with the new request, causing responses to be delivered to the wrong requests.

    This requires an attacker-controlled or compromised upstream HTTP/1.1 server and keep-alive connection     reuse. (CVE-2026-6733)

    When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without     verifying that the pool's origin matches the requested origin. All requests are dispatched through the     pool connected to the first origin, regardless of the intended destination.

    This causes cross-origin request routing: credentials and request data intended for origin B are sent to     origin A, responses from the wrong origin are trusted, and HTTPS requests may be silently downgraded to     HTTP.

    Impacted users are applications that use Socks5ProxyAgent (directly or via setGlobalDispatcher) and make     requests to more than one origin.

    This was introduced in undici 7.23.0 via #4385 and affects all versions through 8.1.0. (CVE-2026-6734)

    Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-     Control header uses whitespace-padded qualified private or no-cache field names such as private=     authorization or no-cache=\tauthorization. The parser preserves the surrounding whitespace, so later     comparisons against the literal authorization field name fail and the response is stored.

    In shared-cache mode, this allows a response containing one user's authenticated data to be served from     cache to a subsequent caller, including an unauthenticated caller, when both requests resolve to the same     cache key.

    Affected applications are those that explicitly enable the cache interceptor (interceptors.cache()) in     shared mode, forward Authorization headers upstream, and receive cacheable responses with non-canonical     qualified private or no-cache directives. (CVE-2026-9678)

    undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded     sequences like %0D%0A, %00, %3B, and %3D into their literal byte equivalents. RFC 6265 SS5.4 does not     specify any decoding and browsers do not decode either.

    Affected applications are those that use undici's cookie parsing (parseSetCookie, parseCookie,     getSetCookies) and forward the parsed cookie value into a response header.

    This was introduced in undici 7.0.0 (CVE-2026-9679)

    undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI     (socks5:// or socks://). The target HTTPS connection through the SOCKS5 tunnel falls back to Node's     default trust store, ignoring user-configured ca, cert, key, rejectUnauthorized, and servername settings.

    Applications that pin to an internal or corporate CA via requestTls.ca will, when their proxy URI is     SOCKS5, get the default Mozilla CA bundle as the trust anchor instead. Any cert signed by any publicly-     trusted CA for the target hostname is accepted, breaking the intended pin and enabling MITM read and     tamper of the HTTPS exchange.

    Affected applications are those that use undici's ProxyAgent (or Socks5ProxyAgent directly) with SOCKS5     AND rely on requestTls for TLS scope restriction. The bug was introduced in undici 7.23.0 when SOCKS5     support was added. (CVE-2026-9697)

An update of the sqlite package has been released.

The version of SQLite installed on the remote host is prior to 3.53.2. It is, therefore, affected by multiple vulnerabilities:

  - A heap-based buffer overflow vulnerability in the FTS5 full-text search extension     allows attackers to cause a crash or execute arbitrary code by supplying a crafted     database with malicious continuation page metadata specifying a szLeaf value smaller     than 4. An integer underflow in fts5ChunkIterate() causes an inflated remaining byte     count during FTS5 MATCH query processing, leading to a heap buffer overflow of     attacker-controlled data.

  - Memory corruption vulnerabilities in the FTS5 full-text search extension allow     attackers to cause process crashes, memory exhaustion, or arbitrary code execution by     supplying a crafted database with malformed FTS5 page data. An out-of-bounds read in     fts5LeafSeek() via an attacker-controlled loop bound and a heap buffer overflow write     in fts5ChunkIterate() through a crafted continuation page causing an integer underflow     are exploitable when an FTS5 MATCH query is executed against the malicious database.
    (CVE-2026-11822)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
