Summary
python-Flask-Cors security update
Details

A Flask extension for handling Cross Origin Resource Sharing (CORS), making cross-origin AJAX possible.

Security Fix(es):

corydolphin/flask-cors is vulnerable to log injection when the log level is set to debug. An attacker can inject fake log entries into the log file by sending a specially crafted GET request containing a CRLF sequence in the request path. This vulnerability allows attackers to corrupt log files, potentially covering tracks of other attacks, confusing log post-processing tools, and forging log entries. The issue is due to improper output neutralization for logs.(CVE-2024-1681)

Severity
