CVE-2026-109336: SurrealDB before 3.3.0 Field Permission Bypass via LIVE SELECT $before/$after

MediumCVSS 5.3 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.22% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. 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 before 3.3.0 contains an authorization bypass vulnerability that allows record users to read fields hidden by field-level SELECT permissions through LIVE SELECT projections. Attackers can project restricted fields from the unreduced $after or $before parameters under an alias to receive exact stored values in CREATE, UPDATE, and DELETE notifications.
