SCA: security update for picomatch (GHSA-c2c7-rcm5-vvqj)

high Tenable Cloud Security Plugin ID 439235

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are vulnerable
to Regular Expression Denial of Service (ReDoS) when processing crafted extglob patterns. Certain patterns
using extglob quantifiers such as `+()` and `*()`, especially when combined with overlapping alternatives
or nested extglobs, are compiled into regular expressions that can exhibit catastrophic backtracking on
non-matching input. Applications are impacted when they allow untrusted users to supply glob patterns that
are passed to `picomatch` for compilation or matching. In those cases, an attacker can cause excessive CPU
consumption and block the Node.js event loop, resulting in a denial of service. Applications that only use
trusted, developer-controlled glob patterns are much less likely to be exposed in a security-relevant way.
This issue is fixed in picomatch 4.0.4, 3.0.2 and 2.3.2. Users should upgrade to one of these versions or
later, depending on their supported release line. If upgrading is not immediately possible, avoid passing
untrusted glob patterns to `picomatch`. Possible mitigations include disabling extglob support for
untrusted patterns by using `noextglob: true`, rejecting or sanitizing patterns containing nested extglobs
or extglob quantifiers such as `+()` and `*()`, enforcing strict allowlists for accepted pattern syntax,
running matching in an isolated worker or separate process with time and resource limits, and applying
application-level request throttling and input validation for any endpoint that accepts glob patterns.
(CVE-2026-33671)

Solution

Update the picomatch library and its related packages to version 2.3.2 or later.
