Description
SurrealDB before 3.1.5 contains an arbitrary file read vulnerability in the DEFINE ANALYZER mapper filter that allows database users with EDITOR or OWNER roles to read files accessible to the SurrealDB process. Attackers can specify arbitrary file paths in the mapper filter and retrieve file contents through query error messages when the SURREAL_FILE_ALLOWLIST is empty or not configured.
