CVE-2026-82069: Improper Removal of Sensitive Information Before Storage or Transfer

A security issue in MongoDB Server's query statistics serialization on the router allows users with monitoring privileges to access unredacted search query text from other users' operations. An improper conditional check in the serialization logic causes the data redaction mechanism to be bypasse...

CVE-2026-82056: Use After Free

A race condition in MongoDB server's text index query parsing can cause a heap use-after-free read when handling upsert retry paths. Under certain concurrent index lifecycle operations, a raw pointer to internal text index metadata may be dereferenced after the underlying structures have been...

CVE-2026-82062: Incorrect Authorization

A security issue in MongoDB Server allows an authenticated user with elevated internal privileges to bypass a disabled feature gate in the applyOps command by specifying an internal replication mode value that was not intended to be client-selectable. This bypass enables execution of container...

CVE-2026-82059: Reachable Assertion

An internal aggregation expression in MongoDB Server was incorrectly registered as accessible to any authenticated user rather than being restricted to internal cluster operations. By crafting a malformed index specification within this expression, an authenticated user with read-only privileges...

CVE-2026-82076: Integer Overflow or Wraparound

An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query...

CVE-2026-82074: Incorrect Authorization

MongoDB Server contains an incorrect authorization vulnerability in the aggregation framework. An authenticated user with minimal privileges can craft a specially formatted aggregation request that causes the server's authorization subsystem to evaluate a different operation than what is actually...

CVE-2026-82064: Reachable Assertion

A security issue in MongoDB Server allows an unauthenticated network user to cause a denial of service on a specific type of replica set member. The server contains an assertion in its read concern processing logic that can be reached without authentication, and the assertion's assumptions about...

CVE-2026-82063: Use After Free

A use-after-free security issue in the cursor management component of MongoDB Server allows an authenticated user to cause a denial of service. Under specific timing conditions during cursor operations, a stale pointer to a freed resource may be retained and subsequently dereferenced during curso...
