CVE-2025-53926Public exploitNetwork attack vector

Client-side script execution via reflected comment fields

Published Jul 16, 2025 · Updated Jul 16, 2025

Reflected XSS in emlog pro-2.5.17 and earlier allows remote attackers to execute script in a victim's browser through a forged comment. The unauthenticated addcom handler returns the comment and comname POST fields in browser-interpreted output without neutralizing script-related HTML. Exploitation requires persuading a victim to visit an attacker-controlled page that submits the forged POST request; the resulting script runs in the emlog site context.
