SCA: security update for markdown-it (GHSA-r7fv-28h4-cvq7)

high Tenable Self-Hosted Container Security Plugin ID 476353

Description

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

 - markdown-it is a Markdown parser. Prior to 14.3.2 and 15.0.2, when typographer: true is enabled, specially
 crafted Markdown can cause quadratic processing time in the smartquotes rule, potentially leading to
 denial of service in applications processing untrusted input. Many opening double quotes followed by
 unmatched closing single quotes cause repeated scans of the entire opener stack. The same issue occurs
 with the quote types reversed. The default configuration (typographer: false) is not affected, but this
 option is enabled with high probability. This issue is fixed in versions 14.3.2 and 15.0.2.
 (CVE-2026-111759)

Solution

Update the markdown-it library and its related packages to version 14.3.2 or later.
