Vulnerability Title
Giskard has a Regular Expression Denial of Service (ReDoS) in RegexMatching Check
Source: NVD (National Vulnerability Database)
Vulnerability Description
Giskard is an open-source testing framework for AI models. In versions prior to 1.0.2b1, the RegexMatching check passes a user-supplied regular expression pattern directly to Python's re.search() without any timeout or complexity guard. A crafted regex pattern can trigger catastrophic backtracking, causing the process to hang indefinitely. Exploitation requires write access to a check definition and subsequent execution of the test suite. This issue has been fixed in giskard-checks version 1.0.2b1.
