The information on this page was manually curated by our Cybersecurity Intelligence Team.
Flask-session-captcha 1.2.1 includes a fix for CVE-2022-24880: In versions prior to 1.2.1, the 'captcha.validate()' function would return 'None' if passed no value (e.g. by submitting an having an empty form). If implementing users were checking the return value to be **False**, the captcha verification check could be bypassed. Users can workaround the issue by not explicitly checking that the value is False. Checking the return value less explicitly should still work.
