Unauthenticated attackers can bypass CAPTCHA protection and submit unlimited questions directly, causing database pollution and triggering outgoing mail notifications.
MEDIUM 6.9EPSS 0.36%
Does this matter?
Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.
Description
phpMyFAQ versions before 4.1.8 fail to validate CAPTCHA when the store parameter is set to 'now' in question submission requests. Unauthenticated attackers can bypass CAPTCHA protection and submit unlimited questions directly, causing database pollution and triggering outgoing mail notifications.
