CVE-2026-13063 Details
Description
An authenticated user with standard read/write privileges can cause the mongod process to terminate due to an out-of-memory condition by sending a crafted aggregation command. MongoDB's libmongocrypt library insufficiently validates payload-supplied values, which can result in an excessively large memory allocation.
A vulnerability exists in MongoDB's handling of aggregation commands that can lead to a denial-of-service condition. An authenticated user with standard read/write privileges can exploit this issue by sending a crafted aggregation command. The vulnerability arises because MongoDB's libmongocrypt library does not properly validate values supplied in the payload, allowing for excessively large memory allocations that can cause the mongod process to terminate.
Users can upgrade to MongoDB versions 8.2.11, 8.2.12, 8.3.7, or 9.0.0-rc1 to address this vulnerability.
