GHSA-J47Q-RC62-W448 fastapi-guard is vulnerable to ReDoS through inefficient regex
Summary fastapi-guard detects penetration attempts by using regex patterns to scan incoming requests. However, some of the regex patterns used in detection are extremely inefficient and can cause polynomial complexity backtracks when handling specially crafted inputs. It is not as severe as...
Regular Expression Denial of Service (ReDoS)
Overview fastapi-guard is a Security library for FastAPI to control IPs and more. Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS via the SusPatternsManager class in the suspatternshandler.py file. An attacker can cause excessive resource consumption...
