Stored script execution via event-handler filter bypass
Published Jul 20, 2025 · Updated Jul 21, 2025
Stored cross-site scripting in ThinkGem JeeSite 5.0 through 5.12.0 allows remote authenticated users to run script in administrators' browsers. The xssFilter regex misses slash-prefixed, mixed-case on* attributes, while affected Beetl templates render user-controlled profile fields without XSS formatting. Exploitation requires an authenticated write to affected profile or office fields and a later view by another user, enabling browser-context data access or actions.
