CVE-2026-127092

Description

BuildAdmin 1.0.1 through 2.3.9 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers to store javascript: URLs in the admin operation log via the X-Rewrite-URL header. When an administrator clicks the log entry's url open button, the script runs in the backend origin and steals the adminInfo token from localStorage, enabling account takeover.
