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.","published":"2026-10-14T19:17:06.000Z","lastModified":"2026-10-16T16:00:34.000Z","status":"Awaiting Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":7.6,"severity":"HIGH","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-287"],"affected":[],"epss":{"score":0.00364,"percentile":0.30048,"date":"2026-10-27","history":[{"date":"2026-10-15","score":0.00364,"percentile":0.28613}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%).
