Jenkins Microsoft Entra Id Previously Azure Ad Plugin
Monthly
Privilege escalation in Jenkins Microsoft Entra ID Plugin (≤710.v0b_ff8e9cc2d2) allows any Entra tenant member with group-creation rights to inherit Jenkins permissions configured for a privileged group by creating a new Entra group whose display name collides with a privileged group's display name. The plugin incorrectly resolves group identity using both the immutable object ID and the mutable, user-controllable display name, so the collision satisfies the authorization check without the attacker belonging to the legitimate privileged group. No public exploit has been identified and CISA has not listed this in KEV, but exploitation requires only a valid Entra account, making it a meaningful insider or tenant-level escalation path into CI/CD infrastructure.
Open redirect in the Jenkins Microsoft Entra ID Plugin (formerly Azure AD Plugin) version 666.v6060de32f87d and earlier allows network-accessible phishing attacks against Jenkins users. The plugin fails to validate the post-login redirect URL, enabling an attacker to craft a legitimate-looking Jenkins authentication link that silently forwards victims to an attacker-controlled site after successful Entra ID login. No active exploitation is confirmed (SSVC: none; EPSS 0.03%, 8th percentile), and the vendor has released a patch per the April 2026 Jenkins security advisory.
