{"schema":"threatline.record/2","record":{"id":"CVE-2026-94613","aliases":["GHSA-cxwx-9x59-28qm"],"summary":"authentik: Denial of Service via Document Type Declarations in SAML Messages","details":"authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an unauthenticated attacker can submit a malformed SAML message to an authentik deployment using SAML in either the identity-provider or SAML source role. The message can stop the worker handling /application/saml/* or /source/saml/*, causing the requests assigned to that worker to fail. Worker process termination and automatic restart do not destroy database-backed sessions, but continued malicious messages can cause a sustained share of legitimate traffic to fail. Other protocol implementations are not affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.","categories":["Unclassified"],"product":"authentik","vendor":"goauthentik","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94613","source_modified_at":"2026-09-29T02:53:23.285Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"authentik","vendor":"goauthentik","versions":[{"version":"< 2026.2.7","status":"affected"},{"version":">= 2026.5.0, < 2026.5.7","status":"affected"},{"version":">= 2026.8.0, < 2026.8.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00643,"percentile":0.50188,"score_date":"2026-10-23"},"published_at":"2026-09-24T16:13:17.785Z","modified_at":"2026-09-29T02:53:23.285Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94613","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T02:53:23.285Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-94613","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/goauthentik/authentik/security/advisories/GHSA-cxwx-9x59-28qm","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/pull/25959","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/pull/25964","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/pull/25969","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/pull/25974","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/commit/03d19d63b8d8dd7bc3de7cf6e57c6df341a9fc86","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/commit/4cf2f803b1c2ef38c224eead375fd057a10ee8ac","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/commit/732adad26bb97361b6bf25ef138df5c16471ba1f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/commit/a029f5372295bfeb1e334855f78601681cdc9a2d","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://docs.goauthentik.io/releases/2026.2#fixed-in-202627","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://docs.goauthentik.io/releases/2026.5#fixed-in-202657","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://docs.goauthentik.io/releases/2026.8#fixed-in-202682","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.2.7","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.5.7","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/goauthentik/authentik/releases/tag/version/2026.8.2","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-29T02:53:11.993694Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T02:53:23.285Z","content_hash":"e7c28aa55c2d3c99c950a2e28f572d139a8ced3666e07dd73771befe5e955e31"}}
