CVE-2026-49997
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSurrealDB is a scalable, distributed, collaborative, document-graph database for the realtime web. Prior to 3.1.0, Document::purge_edges in surrealdb/core/src/doc/delete.rs automatically removed graph edge records with permissions disabled through opt.clone().with_perms(false) when a connected node was deleted, bypassing the edge table's PERMISSIONS FOR delete and PERMISSIONS FOR select clauses. This issue is fixed in version 3.1.0.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIn SurrealDB prior to 3.1.0, the Document::purge_edges function automatically removes graph edge records when a connected node is deleted, but does so with permissions disabled (opt.clone().with_perms(false)). This bypasses the edge table's PERMISSIONS FOR delete and PERMISSIONS FOR select clauses, allowing unauthorized edge deletion and potentially unauthorized edge reading.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check SurrealDB versionRun `surreal --version` from command line, or query the database with `RETURN version();`Affected if Version is earlier than 3.1.0
-
Identify edge tables with custom permissionsQuery system tables to list all tables of type 'edge' that have custom PERMISSIONS FOR delete or PERMISSIONS FOR select clauses definedAffected if Any edge table has explicit delete or select permissions configured and the SurrealDB version is prior to 3.1.0
-
Verify edge deletion behaviorCreate a test node, create an edge with restricted permissions, then delete the node and observe whether the edge is deleted despite restricted permissionsAffected if The edge is automatically deleted when its connected node is deleted, indicating the vulnerability is present
-
Check for unauthorized edge accessAs a restricted user without select permissions on an edge table, attempt to read edges after deleting a connected nodeAffected if Edges can be read or deleted without proper permission checks being enforced
A user is affected if they run SurrealDB versions prior to 3.1.0 and have edge tables with custom PERMISSIONS FOR delete or select clauses that should restrict access but may be bypassed during node deletion.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade SurrealDB to version 3.1.0 or later. Review existing graph edge permission configurations after upgrading to confirm the fix is effective.
