AnalysisAIv1 – Jul 26, 2026

Stored cross-site scripting vulnerability in the Colibri Page Builder WordPress plugin allows authenticated editors or administrators to inject malicious scripts into pages. When other users view the affected page, the script executes, potentially leading to limited data theft, defacement, or session hijacking. Exploitation requires high privileges and user interaction; no active exploitation or public exploit code is known, and EPSS predicts a very low exploitation probability (0.02%).
