CVE-2026-33753

A flaw was found in rfc3161-client, a Python library implementing the Time-Stamp Protocol TSP. This authorization bypass vulnerability allows a remote attacker to impersonate a trusted TimeStamping Authority TSA. The flaw exists in the library's signature verification process, specifically in how...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation through the Verifier.verifyleafcerts logic in src/rfc3161client/verify.py. An attacker can make a timestamp response from a trusted TSA verify as if it came from a different pinned TSA by injecting...
