CVE-2024-6866
MEDIUM5.3EPSS 0.07%Flask-CORS vulnerable to Improper Handling of Case Sensitivity
發布日:2025/3/20修改日:2026/4/28
描述
corydolphin/flask-cors version 4.01 contains a vulnerability where the request path matching is case-insensitive due to the use of the `try_match` function, which is originally intended for matching hosts. This results in a mismatch because paths in URLs are case-sensitive, but the regex matching treats them as case-insensitive. This misconfiguration can lead to significant security vulnerabilities, allowing unauthorized origins to access paths meant to be restricted, resulting in data exposure and potential data leaks.
