CVE-2025-62618

ELOG file upload stored XSS

State: Published
Severity: 8.6 High
Published: Oct 31, 2025
Updated: Nov 4, 2025
Reserved: Oct 16, 2025

Description

ELOG allows an authenticated user to upload arbitrary HTML files. The HTML content is executed in the context of other users when they open the file. Because ELOG includes usernames and password hashes in certain HTTP requests, an attacker can obtain the target's credentials and replay them or crack the password hash offline. In ELOG 3.1.5-20251014 release, HTML files are rendered as plain text.
