CVE-2026-77140 in Telephone Directory Extension
Riassunto
di MITRE • 25/08/2026
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.
