CVE-2026-63763 is a confused deputy privilege escalation vulnerability in SurrealDB before 2.5.0 and before 3.0.0-beta.3. The vulnerability allows unprivileged users to create or modify fields containing futures, functions, or closures, which can be executed with higher-privileged user permissions. This can lead to full privilege escalation, including creation of a root owner and server takeover. Users of SurrealDB before 2.5.0 and before 3.0.0-beta.3 should apply patches or mitigations to prevent exploitation.

Who should care
Users of SurrealDB before 2.5.0 and before 3.0.0-beta.3 should apply patches or mitigations to prevent exploitation. This includes administrators, developers, and security teams responsible for maintaining and securing SurrealDB deployments. Additionally, operators and platform teams should review their systems for potential exposure.
Technical summary
The vulnerability is caused by the execution of futures, functions, or closures in the context of the invoking/querying user rather than their creator. This allows an attacker to plant malicious logic that executes with a higher-privileged user's permissions when that user reads or writes the affected record. The vulnerability affects SurrealDB versions before 2.5.0 and before 3.0.0-beta.3. Users of SurrealDB before 2.5.0 and before 3.0.0-beta.3 should verify their deployments and apply patches or mitigations as necessary to prevent exploitation. This includes reviewing system configurations, monitoring for suspicious activity, and ensuring that all necessary security controls are in place. Additionally, administrators should consider implementing compensating controls for exposed systems while remediation is scheduled and verified.
