SurrealDB: Arbitrary file read via DEFINE ANALYZER mapper() filter
SurrealDB's full-text search lets you define a text analyzer whose `mapper` filter loads a term-mapping file from disk (`DEFINE ANALYZER ... FILTERS mapper(' ')`). A database user with the `EDITOR` or `OWNER` role could point that filter at any file the SurrealDB process can read and have its content returned in the query's error message. File acce...
