Affected: CleanStart: renovate

CVE-2026-2327 affects multiple packages. This issue is resolved in later releases. See references for individual vulnerability details.

Versions of the package markdown-it from 13.0.0 and before 14.1.1 are vulnerable to Regular Expression Denial of Service (ReDoS) due to the use of the regex /\*+$/ in the linkify function. An attacker can supply a long sequence of * characters followed by a non-matching character, which triggers excessive backtracking and may lead to a denial-of-service condition.

Affected: npm: markdown-it
