CVE-2026-96749 Heap out-of-bounds write via signed size overflow in BSON document encoding

An integer overflow in the BSON document encoding component of the MongoDB Python Driver's bundled native extension may occur when a single document is built from an unusually large amount of caller-supplied data. Size arithmetic is performed in a signed 32-bit type, and the guard meant to catch...

CVE-2026-96746

A flaw was found in the MongoDB C Driver. An unauthenticated remote attacker who controls network name resolution and server responses for hosts specified in a client's connection string can trigger an out-of-bounds write in the connection-monitoring logic. By delivering manipulated responses, th...

CVE-2026-96745

A flaw was found in php-pecl-mongodb. In applications utilizing command monitoring, the driver deserializes class names embedded within document content when creating monitoring event objects. An unauthenticated remote attacker can exploit this flaw by providing crafted input during database...

DEBIAN-CVE-2026-96745

Deserialization of untrusted data in the command monitoring support of the MongoDB PHP Driver can cause class names embedded in document content to be honored when the driver builds monitoring event objects. When an application registers a command monitoring subscriber and includes untrusted data...

DEBIAN-CVE-2026-96746

An out-of-bounds write in the connection-monitoring logic of the MongoDB C Driver may allow an unauthenticated party who controls name resolution and the responses of the hosts named in a client's connection string to write beyond the end of a heap buffer. This may cause the application using the...

CVE-2026-96744

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...
