CVE-2026-116214 is a critical-severity weak password recovery mechanism for forgotten password vulnerability in maccms10 from Maccmspro, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected maccms10 versions: 2021.1000.2000 and earlier.

Critical severity: a successful attack would have severe impact.
What to do
- Update maccms10 to 2026.1000.4054 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
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.

The underlying weakness: Weak Password Recovery Mechanism for Forgotten Password
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
How developers prevent this class of flaw
- Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
- Do not use standard weak security questions and use several security questions.
- Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
