Kerentanan Authorization Bypass Through User-Controlled Key. Skor CVSS 4.0 8.7 (High) menurut CNA.

Deskripsi (NVD)

The extension validates the HMAC of a frontend employee edit link only in the action that renders the edit form, not in the action that persists the change. An unauthenticated visitor who knows the UID of a visible employee record can send a direct POST request to the update action and overwrite that record without a valid edit link or any ownership check.
