Unauthorized cache lock takeover via expression injection in lock owner values in MongoDB integration for Laravel

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
