CVE-2026-121422: SurrealDB from 3.1.0 before 3.3.0 SSRF via JWKS Implicit Default Port Bypass

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: surrealdb surrealdb 3.3.0.

Low priority for now. Upgrade to surrealdb surrealdb 3.3.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

SurrealDB from 3.1.0 before 3.3.0 contains a server-side request forgery vulnerability that allows database Owners to bypass port-specific deny-net rules by using JWKS URLs with implicit default ports. Attackers can configure a JWT or record access method whose JWKS URL omits port 80 or 443, causing blind GET requests to explicitly denied internal services.
