Name of the Vulnerable Software and Affected Versions
PIA (affected versions not specified)
Description
The
POST /v1/upload/sbom endpoint accepts a Bearer JWT and validates its unverified iss claim against an issuer allowlist using Python's urlparse before performing OIDC discovery with requests. A discrepancy exists between how urlparse and requests/urllib3 parse authority strings containing backslashes. An attacker can exploit this by crafting an issuer string that bypasses the allowlist check, forcing requests and urllib.request.urlopen to connect to an arbitrary host, port, and scheme during JWKS retrieval. JWKS (JSON Web Key Set) is a set of keys used to verify the signature of a JWT.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
