Background
The Jenkins Project Inheritance Plugin is a Maven ecosystem package that allows for the inheritance of project configurations in Jenkins. It provides a convenient way to define a set of common configurations and reuse them across multiple projects. This plugin is widely used in Jenkins environments to streamline project management and configuration.
Vulnerability Detail
The Jenkins Project Inheritance Plugin version 21.04.03 and earlier is vulnerable to a cross-site scripting (XSS) attack. The plugin fails to properly escape the reason for a build being blocked in tooltips, making it susceptible to XSS attacks. An attacker with control over the reason a queue item is blocked can exploit this vulnerability. The impact of this vulnerability includes potential unauthorized access to sensitive information, session hijacking, and the execution of malicious scripts within the context of the affected user's browser.

Workaround
As a temporary workaround, users can disable the use of tooltips in the Jenkins Project Inheritance Plugin. This can be achieved by modifying the plugin configuration to remove or comment out the tooltip-related code. However, this workaround may impact the user experience and should only be considered until the plugin can be updated to a fixed version.
Conclusion
The Jenkins Project Inheritance Plugin version 21.04.03 and earlier is vulnerable to a cross-site scripting (XSS) attack. It is crucial to update the plugin to version 21.04.04 or later to mitigate this vulnerability. Disabling tooltips can serve as a temporary workaround, but updating to the fixed version is recommended. For further support on vulnerability remediation, please contact DevNack.com.
