SCA: security update for flask-session-captcha (GHSA-7r87-cj48-wj45)

medium Tenable Self-Hosted Container Security Plugin ID 412235

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - flask-session-captcha is a package which allows users to extend Flask by adding an image based captcha
 stored in a server side session. In versions prior to 1.2.1, he `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. Version 1.2.1
 fixes the issue. Users can workaround the issue by not explicitly checking that the value is False.
 Checking the return value less explicitly should still work. (CVE-2022-24880)
