Critical severity GitHub Reviewed Published May 14, 2025 to the GitHub Advisory Database • Updated May 16, 2025

Package

maven io.jenkins.plugins:oidc-provider (Maven)

Affected versions

Description

In Jenkins OpenID Connect Provider Plugin 96.vee8ed882ec4d and earlier the generation of build ID Tokens uses potentially overridden values of environment variables, in conjunction with certain other plugins allowing attackers able to configure jobs to craft a build ID Token that impersonates a trusted job, potentially gaining unauthorized access to external services.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
