Flask is a Python microframework for building web applications open-sourced by Pallets. A security vulnerability exists in Flask version 3.1.0 that stems from mishandling of the key fallback configuration, which could result in session signing with an expired key...

Flask uses fallback key instead of current signing key

In Flask 3.1.0, the way fallback key configuration was handled resulted in the last fallback key being used for signing, rather than the current signing key. Signing is provided by the itsdangerous library. A list of keys can be passed, and it expects the last top key in the list to be the most...

SUSE CVE-2024-6839

corydolphin/flask-cors version 4.0.1 contains an improper regex path matching vulnerability. The plugin prioritizes longer regex patterns over more specific ones when matching paths, which can lead to less restrictive CORS policies being applied to sensitive endpoints. This mismatch in regex...

SUSE CVE-2024-6844

A vulnerability in corydolphin/flask-cors version 4.0.1 allows for inconsistent CORS matching due to the handling of the '+' character in URL paths. The request.path is passed through the unquoteplus function, which converts the '+' character to a space ' '. This behavior leads to incorrect path...

SUSE CVE-2024-6866

corydolphin/flask-cors version 4.01 contains a vulnerability where the request path matching is case-insensitive due to the use of the trymatch function, which is originally intended for matching hosts. This results in a mismatch because paths in URLs are case-sensitive, but the regex matching...
