Chainguard: kibana-9.5: security update to 9.5.5-r7

high Tenable Cloud Security Plugin ID 478019

Description

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

 - RE2JS is the JavaScript port of RE2, a regular expression engine that provides linear time matching. From
 2.2.0 until 2.8.7, enabling LOOKBEHINDS and using repeated matching through matcher().find(), matchAll(),
 split(), or matcher().replaceAll() can cause quadratic total work. Machine.match restarts lookbehind
 scanning from offset zero for each requested start position, while Matcher-based APIs request capture
 slots that prevent the early exit used for captureless matching. Dense matches therefore repeatedly rescan
 the input, allowing attacker-influenced text to monopolize a single-threaded worker and deny service. This
 issue is fixed in version 2.8.7. (CVE-2026-116795)

Solution

Update the kibana-9.5 library and its related packages to version 9.5.5-r7 or later.
