CVE-2026-63744 surrealdb CVE debrief

A server-side request forgery vulnerability was discovered in SurrealDB before version 3.1.5. The vulnerability exists in the JWKS fetcher, which follows HTTP redirects without re-validating redirect targets against network capabilities. This allows attackers with Owner role to configure a JWKS URL pointing to an allowlisted host that redirects to blocked internal addresses, bypassing network access controls. The vulnerability has a CVSS score of 5.1 and a severity of MEDIUM.

Who should care

Users of SurrealDB, especially those with administrative access, should be aware of this vulnerability and take steps to mitigate it. This includes updating to version 3.1.5 or later and reviewing their network access controls. Additionally, security teams and vulnerability management teams should review their configurations and implement additional security measures to prevent SSRF attacks.

Technical summary

The vulnerability is caused by the JWKS fetcher's inability to re-validate redirect targets against network capabilities. This allows attackers to bypass network access controls by configuring a JWKS URL that points to an allowlisted host that redirects to a blocked internal address. The vulnerability has a CVSS score of 5.1 and a severity of MEDIUM. SurrealDB versions before 3.1.5 are affected, and updating to version 3.1.5 or later is recommended.

Defensive priority

High

Recommended defensive actions

  • Update SurrealDB to version 3.1.5 or later
  • Review and restrict network access controls
  • Monitor for suspicious activity
  • Implement additional security measures to prevent SSRF attacks
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The vulnerability was reported by Vulncheck and is tracked under CVE-2026-63744. The NVD entry is currently awaiting analysis. Evidence of exploitation has not been reported, but defenders should verify network access controls and review their configurations to prevent potential SSRF attacks.
