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.","state":0,"publishedAt":"2026-10-14T18:57:50.768+00:00","modifiedAt":"2026-10-15T14:23:19.741+00:00","affected":[{"ecosystem":"Vendor product","name":"sentry","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getsentry\",\n                    \"product\": \"sentry\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 26.5.0, < 26.7.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.6,"severity":"HIGH"}],"references":["https://github.com/getsentry/sentry/security/advisories/GHSA-w699-8wff-fqxw","https://github.com/getsentry/sentry/pull/120467","https://github.com/getsentry/sentry/pull/120702","https://github.com/getsentry/sentry/commit/9c982d4bcb81c93e2db552084bcbb45cdd34bdd3","https://github.com/getsentry/sentry/commit/ec963de4ec8c7f340f286c6f613e55458a9e5ddf","https://github.com/getsentry/self-hosted/releases/tag/26.7.2","https://github.com/getsentry/sentry/releases/tag/26.7.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102899","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102899","identifiers":["CVE-2026-102899"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
