CVE-2026-63744: SurrealDB before 3.1.5 SSRF via JWKS URL Redirect

MediumCVSS 5.1 · v4.0—No exploit Fix available

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: 0.32% (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 3.1.5.

Low priority for now. Upgrade to surrealdb surrealdb 3.1.5 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 before 3.1.5 contains a server-side request forgery vulnerability in the JWKS fetcher that follows HTTP redirects without re-validating redirect targets against network capabilities. Attackers with Owner role can configure a JWKS URL pointing to an allowlisted host that redirects to blocked internal addresses, bypassing network access controls.
