This vulnerability, known as Regular Expression Denial of Service (ReDoS), allows a remote attacker to provide specially crafted regular expressions to the public detection API. This can cause catastrophic backtracking, leading to a worker process consuming 100% CPU indefinitely and resulting in a denial of service for the entire guardrails-mediated LLM pipeline.","state":0,"publishedAt":"2026-07-08T19:50:51.563+00:00","modifiedAt":"2026-09-30T16:55:29.743+00:00","affected":[{"ecosystem":"https://github.com/trustyai-explainability/guardrails-detectors","name":"guardrails-detectors","ranges":[],"versions":[],"rawVersionEvidence":"{\n
