Official 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.

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
