SurrealDB: Field-level SELECT permissions bypassed via indexed COUNT fast paths

A record user could learn the value of a hidden field by counting how many records match a guess. When DEFINE FIELD ... PERMISSIONS FOR select WHERE ... hides a field's contents from a caller, and that field is indexed, running SELECT count FROM t WHERE hiddenfield = "guess" GROUP ALL returned a...

SurrealDB: Port-specific --deny-net rules silently bypassed on HTTP redirect

SurrealDB offers http:: functions that can access external network endpoints, with the --allow-net and --deny-net capabilities used to restrict the set of network targets that can be reached. An authenticated user of SurrealDB can bypass a port-scoped --deny-net : rule by chaining an HTTP redirec...

SurrealDB: Authenticated callers can read fields hidden by field-level SELECT permissions via error messages

A record user with UPDATE access could read field values that field-level SELECT permissions hid from them. Arithmetic operators and extend embedded the raw operand into their error messages, and UPDATE permission checks evaluate against the unreduced document — so triggering such an error agains...

SurrealDB: Scraping a TABLE with no available PERMISSIONS to current auth level

A vulnerability was discovered where the user-supplied WHERE clause in a SELECT statement is evaluated against the full record data before PERMISSIONS FOR SELECT WHERE determines whether the principal is authorised to access that record. A side-effecting expression in the WHERE clause can...
