SCA: security update for postcss (GHSA-fxqj-rqcc-2cmp)

medium Tenable Cloud Security Plugin ID 445584

Description

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

 - PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules
 into an Abstract Syntax Tree. Prior to 8.5.19, if from is unset, an attacker can cause
 PreviousMap.loadFile() to read an unintended source-map file by supplying an absolute or directory-
 traversal sourceMappingURL. The resulting map’s sources and sourcesContent may then be exposed to the
 application. This issue is fixed in version 8.5.19. (CVE-2026-69153)

Solution

Update the postcss library and its related packages to version 8.5.23 or later.
