NoSQL injection via unquoted constant GroupBy keys in LINQ pipeline translation

A NoSQL/expression injection weakness exists in the LINQ-to-aggregation query translation layer of the MongoDB C Driver, in both aggregation expression and query filter translation. When application-supplied values are embedded in certain query constructs, special elements contained within those...

CVE-2026-81527

CVE-2026-81527 is a NoSQL/expression injection flaw in the MongoDB C# Driver , specifically in the LINQ-to-aggregation query translation layer affecting both aggregation expression and query filter translation. The root cause is that unquoted constant GroupBy keys in LINQ pipeline translation are...

CVE-2026-81524

MongoDB C Driver is vulnerable to cross-tenant database retargeting caused by dot and NUL injection in namespace strings. Special characters in caller-supplied database and collection name components pass without sanitization when the driver composes the target namespace, allowing an application ...

CVE-2026-81524 Cross-tenant database retargeting via dot/NUL injection in namespace strings in the C Driver

A weakness in the MongoDB C Driver allows special elements in caller-supplied database and collection name components to pass without sanitization when the driver composes the target namespace for an operation. An application that incorporates untrusted input into these name components can have...

CVE-2026-81522 Cross-tenant database retargeting via dot/NUL injection in namespace strings in the C++ Driver

A weakness in the MongoDB C++ Driver's handling of caller-supplied namespace identifiers allows special characters embedded in those identifiers. An application that builds a namespace identifier from untrusted input without validating it may therefore have its operation directed at a different...

CVE-2026-81522

CVE-2026-81522 affects the MongoDB C++ Driver and involves improper handling of caller-supplied namespace identifiers. The root cause is that special characters—specifically dot and NUL characters —embedded in those identifiers can cause an application's operation to be directed at a different da...

PT-2026-82742

A MongoDB C driver document-replacement code path omits the element-name/shape validation that the equivalent write paths apply, so a value supplied as a replacement is forwarded to the server without neutralization of query-language special elements. An application that passes untrusted,...
