CVE-2026-6824Network attack vector

Stored script execution via unsanitized module input

Published May 29, 2026 · Updated May 29, 2026

Stored XSS in CP PLUS CP-UNR-108F1 allows remote authenticated users to execute scripts in other users' browsers via stored input. Affected functional modules store user-supplied input on the device backend without sufficient sanitization and later render it in authenticated interface pages. Administrative privileges are required to inject the payload, and another user must open an affected page; execution can compromise sessions, perform actions with that user's privileges, and expose or alter sensitive data.
