Inefficient Regular Expression Complexity (CWE-1333) in the AI Inference Anonymization Engine in Kibana can lead Denial of Service via Regular Expression Exponential Blowup (CAPEC-492).
AnalysisAI
Kibana's AI Inference Anonymization Engine contains a ReDoS (Regular Expression Denial of Service) vulnerability that allows authenticated high-privilege users to crash the service through maliciously crafted input. An attacker with administrative credentials can trigger exponential regex backtracking to render the system unavailable, though no patch is currently available.
Technical ContextAI
Classified as CWE-1333 (Inefficient Regular Expression Complexity (ReDoS)). Affects the Kibana can lead Denial of component of Kibana. Inefficient Regular Expression Complexity (CWE-1333) in the AI Inference Anonymization Engine in Kibana can lead Denial of Service via Regular Expression Exponential Blowup (CAPEC-492).
