Published: 2026-09-24 · updated 2026-09-24
Weakness: CWE-943

Description

Improper neutralization of special elements in data query logic in the cache lock implementation of the MongoDB integration for Laravel can cause a caller-supplied lock owner value to be evaluated as an aggregation expression rather than as a literal value. An authenticated user who can influence the owner value an application uses when acquiring or restoring a lock may take over or prematurely expire a lock held by another process, which can lead to duplicated or conflicting operations.
