n8n: Regular Expression Denial of Service in the Default Blocked-File-Pattern Match via a Git Node Clone Path

Impact The Git node's clone operation matched the destination path against the default N8NBLOCKFILEPATTERNS expression, which was written so that a crafted path caused catastrophic backtracking. Evaluation runs synchronously in the main n8n process, so an authenticated user could freeze the...

The vulnerability of the Actor.name_email_regex() function in the Python library for interacting with Git repositories in GitPython allows a malicious actor to trigger a denial-of-service attack.

The vulnerability of the Actor.nameemailregex function in the Python library for interacting with Git repositories in GitPython is related to the use of a regular expression with inefficient computational complexity. Exploiting this vulnerability could allow a malicious actor to cause service...
