AnalysisAIv2 – Jul 26, 2026

Cross-site scripting in Emlog Pro up to 2.5.7 allows remote authenticated attackers to inject web scripts via the active_post parameter in /admin/article.php. A low-privileged user can craft a malicious URL that, when clicked by an admin, executes arbitrary JavaScript in the admin's browser. Exploit code is publicly available, but EPSS indicates low exploitation probability (0.07%) and the vulnerability is not listed in CISA KEV.
