{"id":"CVE-2026-15154","summary":"Guardrails-detectors: guardrails-detectors: unauthenticated regular-expression denial of service (redos) via detector_params.regex","details":"A flaw was found in `guardrails-detectors`, a component of Red Hat OpenShift AI. 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.","modified":"2026-10-08T02:50:39.324615816Z","published":"2026-07-08T19:50:51.563Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15154.json","cna_assigner":"redhat","cwe_ids":["CWE-1333"]},"references":[{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:53261"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:53262"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:53263"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:60520"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:65126"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:73987"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-15154"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/15xxx/CVE-2026-15154.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15154"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2498188"},{"type":"PACKAGE","url":"https://github.com/trustyai-explainability/guardrails-detectors"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/trustyai-explainability/guardrails-detectors","events":[{"introduced":"0"},{"fixed":"d857e059f8a2dedb5c7ea9a2c307c4cfd7983fd1"}]}],"versions":["v0.3.0","v0.2.0","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-15154.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
