CVE-2026-12616

The /v1/upload/sbom endpoint extracts the iss claim from the attacker-supplied JWT with signature verification disabled, then interpolates that string into three log statements before any validation gate. Because the configured log format ("%(asctime)s - %(name)s - %(levelname)s - %(message)s") renders newlines literally, an unauthenticated attacker can forge log records that are byte-for-byte indistinguishable from PIA's genuine "Successfully authenticated project" message. PIA is an authentication broker whose logs are explicitly relied upon for incident response (DESIGN.md §5.4 lists "Token verifications" and "Errors" as events to log), so the ability to plant fake auth-success entries directly undermines the audit trail the service exists to produce.
