CVE-2026-89099
Race Condition in MongoDB Server Document Value Layer Leads to Memory Corruption
CVSS Score
7.5
EPSS Score
0.0%
EPSS Percentile
0th
A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.
