CVE-2026-121417 Details
Description
SurrealDB before 3.3.0 contains a use-after-free vulnerability in surrealdb-core KV backends that pass borrowed transaction state into affinitypool::spawn_local closures relying on future Drop for safety. Rust embedders that leak a dispatched future (e.g. via mem::forget) and drop the transaction cause pool workers to read and write freed memory, risking crashes or memory corruption.
A use-after-free vulnerability has been identified in SurrealDB versions prior to 3.3.0. This issue resides within the 'surrealdb-core' KV backends that pass borrowed transaction state into 'affinitypool::spawn_local' closures, relying on the future's 'Drop' for safety. Rust embedders that inadvertently leak a dispatched future, such as through 'mem::forget', while dropping the transaction, can cause pool workers to access freed memory. This mismanagement risks crashes or memory corruption.
Users are advised to upgrade to SurrealDB version 3.3.0 or later, where this vulnerability has been patched.
