Kerentanan Inefficient Regular Expression Complexity pada markdown-it project markdown-it. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

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.
