Immutable.js provides many Persistent Immutable data structures. Prior to versions 3.8.3, 4.3.7, and 5.1.5, Prototype Pollution is possible in immutable via the mergeDeep(), mergeDeepWith(), merge(), Map.toJS(), and Map.toObject() APIs. This issue has been patched in versions 3.8.3, 4.3.7, and 5.1.5.

    (CVE-2026-29063)

  - When parsing a Range header containing a large number of small ranges, FileServer(FS), ServeContent, and     ServeFile(FS) can consume an excessive amount of CPU. (CVE-2026-78667)

  - Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send     a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple     references. We now reject these as malformed and curb the memory amplification vector as a result.

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1792757203 advisory.

  - Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when extracting plugin archives.
    A crafted plugin archive can chain relative symbolic link entries to escape the plugin installation     directory, writing arbitrary files and an executable backend binary outside that directory. The dropped     executable runs with the privileges of the Grafana server process, resulting in remote code execution.
    Plugin archives are extracted before their signature is verified, so a valid plugin signature does not     prevent the write. An operator can therefore be affected by installing a plugin that appears legitimate,     as well as by installing a plugin from an arbitrary archive using grafana-cli, the GF_INSTALL_PLUGINS     environment variable, or preinstall configuration. Grafana Enterprise is affected because it includes the     same plugin extraction code as Grafana OSS. (CVE-2026-15815)

Prior to versions 3.8.3, 4.3.7, and     5.1.5, Prototype Pollution is possible in immutable via the mergeDeep(), mergeDeepWith(), merge(),     Map.toJS(), and Map.toObject() APIs. This issue has been patched in versions 3.8.3, 4.3.7, and 5.1.5.
    (CVE-2026-29063)

  - Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body     before processing it. An attacker can send very large payloads that force excessive memory allocation,     potentially exhausting memory and causing a denial of service. (CVE-2026-33382)

  - js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 before 3.15.0 and from 4.0.0 before 4.3.0, js-     yaml can spend quadratic CPU time parsing a document whose size grows only linearly when a chain of     mappings uses merge keys where each mapping merges the previous one. This issue is fixed in versions     3.15.0 and 4.3.0. (CVE-2026-59869)

  - js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 until 3.15.2, 4.3.2, and 5.4.1,     maxTotalMergeKeys in lib/js-yaml/loader.js and lib/loader.js does not count empty mapping sources while     processing the merge key <<. An attacker can alias a large sequence of empty mappings into many merge     targets, causing O(N * K) processing while totalMergeKeys remains unchanged and the configured resource     limit is never reached. A relatively small YAML document can therefore cause prolonged CPU consumption in     applications that parse untrusted YAML, and merge processing is enabled by default on these release lines.
    In v3 & v4, merge is enabled by default so the severity score is higher. This issue is fixed in versions     3.15.2, 4.3.2, and 5.4.1. (CVE-2026-84375)
