The vulnerability was disclosed on July 27, 2022, and is characterized by a missing permission check in an HTTP endpoint. This vulnerability affects the Jenkins Deployer Framework Plugin, which is a component used for deployment operations in Jenkins (Jenkins Advisory).

The vulnerability is classified as Medium severity based on the CVSS scoring system. The core issue stems from the plugin's failure to perform necessary permission checks in an HTTP endpoint. This security flaw specifically affects the deployment logs access functionality within the plugin. The vulnerability exists in versions up to and including 85.v1d1888e8c021 of the Deployer Framework Plugin (Jenkins Advisory).

The vulnerability allows attackers with Item/Read permission to read deployment logs without having the required Deploy Now/Deploy permission. This unauthorized access to deployment logs could potentially expose sensitive information contained within these logs (Jenkins Advisory).
