CVE-2026-5430WSO2 API Products — Forged Token Authentication Flaw

The vendor record says these gateway products accept signed web tokens (JWT) made with unsupported algorithms, so a forged one can take over admin accounts. The exploited-flaw catalog instead describes a path traversal leading to RCE, so the sources conflict.
