Vulnerability details
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to initialization of a resource with an insecure default in the pathsec security module when processing security validation checks with ENFORCE disabled by default. A remote attacker can supply a crafted path or unsafe source to bypass security checks and disclose sensitive information.
The module emits RuntimeWarning messages instead of raising exceptions, so execution continues after a violation is detected.
