{"schema":"threatline.record/2","record":{"id":"CVE-2026-102899","aliases":["GHSA-w699-8wff-fqxw"],"summary":"Sentry: Improper authentication on SAML SSO process allows user identity linking","details":"Sentry is an application monitoring and error tracking platform. From 26.5.0 until 26.7.2, the SAML SSO identity-linking flow allows an attacker who controls a SAML identity provider to socially engineer an authenticated user into opening a malicious URL, link the attacker's identity to the victim's Sentry account, and take control of that account. The attack requires a browser that accepts the cross-site cookie context, including Firefox with SameSite=None cookies or Chromium with third-party cookies enabled. Sentry SaaS received the remediation on July 27, 2026, and self-hosted Sentry is fixed in version 26.7.2.","categories":["Unclassified"],"product":"sentry","vendor":"getsentry","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102899","source_modified_at":"2026-10-15T14:23:19.741Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"sentry","vendor":"getsentry","versions":[{"version":">= 26.5.0, < 26.7.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.6,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00364,"percentile":0.29054,"score_date":"2026-10-23"},"published_at":"2026-10-14T18:57:50.768Z","modified_at":"2026-10-15T14:23:19.741Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102899","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T14:23:19.741Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102899","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/getsentry/sentry/security/advisories/GHSA-w699-8wff-fqxw","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/getsentry/sentry/pull/120467","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/getsentry/sentry/pull/120702","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/getsentry/sentry/commit/9c982d4bcb81c93e2db552084bcbb45cdd34bdd3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/getsentry/sentry/commit/ec963de4ec8c7f340f286c6f613e55458a9e5ddf","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/getsentry/self-hosted/releases/tag/26.7.2","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/getsentry/sentry/releases/tag/26.7.2","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":"no","technical_impact":"total","assessed_at":"2026-10-15T14:22:26.114527Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T14:23:19.741Z","content_hash":"c9c33bd1f68bd35bb6ec0d96bac88500a936a27bd6c5882d67a8c2e14bfcacbc"}}
