AI-suggested
Upgrade soapbar to version 0.13.0 or later, where the verify_envelope_bsp() function properly validates certificates with a trusted CA chain and other checks. No additional mitigation is required once patched.
Description
A vulnerability in the soapbar Python SOAP library prior to version 0.13.0 allows improper certificate validation in the verify_envelope_bsp() function. This function trusted the certificate embedded in the message without validating the certificate chain or issuer, enabling attackers to forge signatures and bypass authentication. The issue was fixed in version 0.13.0.
