Vulnerability	Vulnerable Version
M Inefficient Algorithmic Complexity markdown-it is a modern pluggable markdown parser. Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity through the `replaceAt()` function in the smartquotes rule when processing markdown input with a large number of consecutive quotation marks and the `typographer` option enabled. An attacker can cause excessive CPU consumption and disrupt service availability by submitting specially crafted markdown content containing many quote characters. How to fix Inefficient Algorithmic Complexity? Upgrade `markdown-it` to version 14.2.0 or higher.	<14.2.0
M Regular Expression Denial of Service (ReDoS) markdown-it is a modern pluggable markdown parser. Affected versions of this package 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. How to fix Regular Expression Denial of Service (ReDoS)? Upgrade `markdown-it` to version 14.1.1 or higher.	>=13.0.0 <14.1.1
H Infinite loop markdown-it is a modern pluggable markdown parser. Affected versions of this package are vulnerable to Infinite loop in linkify inline rule when using malformed input. How to fix Infinite loop? Upgrade `markdown-it` to version 13.0.2 or higher.	<13.0.2
