| Title | turndown npm v7.2.1 Inefficient Regular Expression Complexity |
|---|
| Description | The vulnerability exists in two rules that use a regular expression with a greedy quantifier (+) followed by an end-of-string anchor ($). When processing a long, specially crafted string that "almost" matches, the regex engine's backtracking can lead to an exponential increase in computation time, causing the application to hang. |
