CVE-2026-116215

MacCMS v10 through 2026.1000.4056 contains a mass assignment vulnerability in index/Comment::saveData() that allows unauthenticated attackers to set arbitrary mac_comment columns including user_id. Attackers can submit anonymous comments with a crafted user_id parameter to attribute them to any registered member, displaying that member's avatar and impersonating them.

MacCMS v10 before 2026.1000.4054 contains an authentication bypass vulnerability that allows unauthenticated attackers to reset any member's password because check_msg() never compares msg_to. Attackers can request a recovery code to their own mailbox via user/findpass_msg, then submit it to user/findpass_reset with the victim's email or phone to take over the account.

Maccms 8.x allows remote command execution via the wd parameter in an index.php?m=vod-search request.

MacCMS v10 through 2026.1000.4056 does not limit attempts on the six-digit password recovery code, allowing unauthenticated attackers to take over member accounts. Attackers knowing a victim's email or phone can request a code and brute-force findpass_reset to overwrite the member's password.

Incorrect Access Control vulnerability in the /api.php/user/get_list endpoint in Maccms v10 v2026.1000.4055. The interface fails to perform any authentication or authorization checks. An unauthenticated remote attacker can send a crafted HTTP GET request with limit and offset parameters to paginate and retrieve sensitive information of all registered users.
