CVE-2026-5569Public exploitNetwork attack vector

Unauthenticated administrative control via unvalidated URL tokens

Published Apr 5, 2026 · Updated Apr 5, 2026

Improper access control in Technostrobe HI-LED-WR120-G2 5.5.0.1R6.03.30 allows remote attackers to alter controller settings. The embedded web server serves management pages for attacker-supplied userId and keyId URL values without validating a session, signature, or account, while /LoginCB accepts unauthenticated password changes. Network access to the web service is sufficient to read status data, change passwords and alarm settings, and gain administrative control.
