Microsoft Jira Saml Sso Plugin
Monthly
Authentication bypass in Microsoft's SAML SSO plugins for Atlassian Jira (versions 1.0.0 through 1.3.2) and Confluence (versions 1.0.0 through 7.3.x) allows a remote, unauthenticated attacker to impersonate other users and elevate privileges over the network due to an incorrectly implemented authentication algorithm. Rated CVSS 9.1 with full confidentiality and integrity impact, the flaw is deemed automatable with total technical impact by CISA's SSVC framework, though EPSS remains low (0.12%) and no public exploit has been identified at time of analysis. A vendor patch is available.
