  "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.", "A flaw was found in markdown-it. A remote attacker can exploit this Regular Expression Denial of Service (ReDoS) vulnerability by providing a specially crafted input containing a long sequence of asterisk characters followed by a non-matching character to the `linkify` function. This triggers excessive backtracking in the regular expression, leading to a denial-of-service condition." ],
