Summary

In Stapler 2107.v8dfcb_e8ed317 and earlier, except 2088.2093.vd7c3e58008a_6, included in Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, form data binding allows setting public static fields of the bound configuration object. Attackers who can submit configuration forms can modify public static fields of the configuration objects those forms are bound to, resulting in changes that apply globally to the Jenkins instance.

Risk Assessment

An attacker with the ability to submit configuration forms can alter global Jenkins settings, potentially compromising configuration integrity and enabling further attacks.

Recommendation

Update Jenkins and Stapler to versions containing the fix as soon as available.
