CVE-2024-1681: Corydolphin Flask-Cors

Medium severity, CVSS 5.3. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
