It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1743 advisory.

    When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of     C memory and a crash. (CVE-2026-33811)

    When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION     frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0. (CVE-2026-33814)

    The go tool pack subcommand (usually used only by the compiler as an internal tool with known-good     inputs) does not sanitize output filenames. Extracting a malicious archive file with the pack subcommand     can write files to arbitrary locations on the filesystem. (CVE-2026-39817)

    The go bug command writes to two files with predictable names in the system temporary directory (for     example, /tmp). An attacker with access to the temporary directory can create a symlink in one of these     names, causing go bug to overwrite the target of the symlink. (CVE-2026-39819)

    Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive     CPU exhaustion and memory allocations. (CVE-2026-39820)

    CVE-2026-27142 fixed a vulnerability in which URLs were not correctly escaped inside of a <meta> tag's     <content> attribute. If the URL content were to insert ASCII whitespaces around the '=' rune inside of the     <content> attribute, the escaper would fail to similarly escape it, leading to XSS. (CVE-2026-39823)

    ReverseProxy can forward queries containing parameters not visible to Rewrite functions. When used with a     Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the     forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not     take ParseQuery's limit on the total number of query parameters (controlled by     GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a     query parameter that is not visible to the Rewrite function. For example, the query     a1=x&a2=x&...&a10000=x&hidden=y can forward the parameter hidden=y while hiding it from the proxy's     Rewrite function. (CVE-2026-39825)

    If a trusted template author were to write a <script> tag containing an empty 'type' attribute or a 'type'     attribute with an ASCII whitespace, the execution of the template would incorrectly escape any data passed     into the <script> block. (CVE-2026-39826)

    Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC     5322. (CVE-2026-42499)

    A malicious module proxy can exploit a flaw in the go command's validation of module checksums to bypass     checksum database validation. This vulnerability affects any user using an untrusted module proxy     (GOMODPROXY) or checksum database (GOSUMDB). A malicious module proxy can serve altered versions of the Go     toolchain. When selecting a different version of the Go toolchain than the currently installed toolchain     (due to the GOTOOLCHAIN environment variable, or a go.work or go.mod with a toolchain line), the go     command will download and execute a toolchain provided by the module proxy. A malicious module proxy can     bypass checksum database validation for this downloaded toolchain. Since this vulnerability affects the     security of toolchain downloads, setting GOTOOLCHAIN to a fixed version is not sufficient. You must     upgrade your base Go toolchain. The go tool always validates the hash of a toolchain before executing it,     so fixed versions will refuse to execute any cached, altered versions of the toolchain. The go tool trusts     go.sum files to contain accurate hashes of the current module's dependencies. A malicious proxy exploiting     this vulnerability to serve an altered module will have caused an incorrect hash to be recorded in the     go.sum. Users who have configured a non-trusted GOPROXY can determine if they have been affected by     running rm go.sum ; go mod tidy ; go mod verify, which will revalidate all dependencies of the current     module. The specific flaw in more detail: The go command consults the checksum database to validate     downloaded modules, when a module is not listed in the go.sum file. It verifies that the module hash     reported by the checksum database matches the hash of the downloaded module. If, however, the checksum     database returns a successful response that contains no entry for the module, the go command incorrectly     permitted validation to succeed. A module proxy may mirror or proxy the checksum database, in which case     the go command will not connect to the checksum database directly. Checksums reported by the checksum     database are cryptographically signed, so a malicious proxy cannot alter the reported checksum for a     module. However, a proxy which returns an empty checksum response, or a checksum response for an unrelated     module, could cause the go command to proceed as if a downloaded module has been validated.
