CVE-2026-81527

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...

EUVD-2026-67212

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,...

CVE-2026-81528

CVE-2026-81528 affects the MongoDB C# driver , where the document-replacement code path omits the element-name/shape validation applied by equivalent write paths. This allows NoSQL injection : an application passing untrusted, loosely-typed input as a replacement value can have that input interpr...
