The vulnerability stems from a missing permission check in methods implementing form validation in the OpenShift Deployer Plugin. This security flaw is part of a broader issue tracked as SECURITY-1375 (2) that also includes a related CSRF vulnerability (CVE-2022-36908). The vulnerability specifically relates to the plugin's form validation methods that handle file path verification and SSH key file uploads (Jenkins Advisory).

The vulnerability allows attackers with Overall/Read permission to check for the existence of attacker-specified file paths on the Jenkins controller file system and to upload SSH key files from the Jenkins controller file system to attacker-specified URLs. This creates a potential security risk for unauthorized file system access and data exfiltration (Jenkins Advisory).

As of the advisory's publication date, no official fix was available for this vulnerability in the OpenShift Deployer Plugin. The plugin version 1.2.0 and earlier remain vulnerable, and no updated version has been released to address this security issue (Jenkins Advisory).
