What is CVE-2026-121422?

SurrealDB versions from 3.1.0 prior to 3.3.0 are vulnerable to a server-side request forgery (SSRF) flaw. This vulnerability allows database owners to exploit bypass mechanisms of port-specific deny-net rules by accessing JWKS URLs that omit default ports like 80 or 443. Consequently, attackers can send blind GET requests, potentially reaching and compromising internal services that are otherwise restricted. It is crucial for users of affected versions to apply necessary patches and updates to mitigate this risk.

Affected Version(s)

surrealdb 3.1.0 < 3.3.0

surrealdb 3.3.0
