SurrealDB before 2.5.0 and before 3.0.0-beta.3 contains a confused deputy privilege escalation vulnerability. Unprivileged users (e.g., those with the database editor role) can create or modify fields containing futures, functions, or closures. Because these are executed in the context of the invoking/querying user rather than their creator, an attacker can plant malicious logic that executes with a higher-privileged user's permissions when that user reads or writes the affected record. This can lead to full privilege escalation, including creation of a root owner and server takeover.
CVE-2026-63763
This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
