SCA: security update for re2 (GHSA-ff84-5f28-78qj)

medium Tenable Cloud Security Plugin ID 445543

Description

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

 - re2 provides Node.js bindings for Google's RE2 regular expression engine. Prior to 1.25.2, re2 validates
 lastIndex against the UTF-8 byte length of a subject but uses it as a UTF-16 code-unit offset in exec,
 test, match, replace, and split, allowing an attacker-influenced lastIndex on a non-ASCII subject to
 trigger an out-of-bounds heap read and an uncatchable process crash, with limited heap information
 disclosure in some cases. This issue is fixed in 1.25.2. (CVE-2026-67550)

Solution

Update the re2 library and its related packages to version 1.25.2 or later.
