path-to-regexp: Backtracking regular expressions cause ReDoS

A flaw was found in path-to-regexp package, where it turns path strings into regular expressions. In certain cases, path-to-regexp will output a regular expression that can be exploited to cause poor performance. Because JavaScript is single-threaded and regex matching runs on the main thread, po...

CVE-2024-53981

python-multipart is a streaming multipart parser for Python. When parsing form data, python-multipart skips line breaks CR \r or LF \n in front of the first boundary and any tailing bytes after the last boundary. This happens one byte at a time and emits a log event each time, which may cause...

path-to-regexp outputs backtracking regular expressions

Impact A bad regular expression is generated any time you have two parameters within a single segment, separated by something that is not a period .. For example, /:a-:b. Patches For users of 0.1, upgrade to 0.1.10. All other users should upgrade to 8.0.0. These versions add backtrack protection...
