CVE-2026-81530

MongoDB C# Driver has a weakness in its client-side encryption configuration where KMS key-management credentials supplied by the application are serialized verbatim into the driver's human-readable diagnostic settings representation instead of being masked like other secret fields. An attacker w...

CVE-2026-81529

This HIGH severity (CVSS 3.1: 7.1) vulnerability affects the MongoDB C# Driver (NuGet: MongoDB.Driver). The root cause is improper neutralization of delimiters in the connection-URL builder: when untrusted text is passed into the builder and the result is round-tripped back into a client configur...

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...

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...

megaco: Erlang/OTP Megaco Flex Scanner: Remote code execution or denial of service via oversized message

A flaw was found in the Erlang/OTP megaco flex scanner C driver. A remote, unauthenticated attacker can exploit a buffer overflow vulnerability by sending a specially crafted H.248/Megaco message with an oversized property parameter name. This can lead to memory corruption, potentially allowing f...

Linux Distros Unpatched Vulnerability : CVE-2026-9100

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection...

CVE-2026-9100

A flaw was found in the MongoDB C Driver's legacy GridFS API. This vulnerability allows an attacker to craft malicious documents in a GridFS collection. When an application reads these crafted files via the legacy API, it may either crash due to a division-by-zero error, leading to a Denial of...

UBUNTU-CVE-2026-9100

The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash via a division-by-zero or silently leak process memo...

CVE-2026-6691

A flaw was found in the MongoDB C Driver's Cyrus SASL integration. This vulnerability, a heap buffer overflow, occurs due to unsafe string copying during username canonicalization. A remote attacker can exploit this by providing untrusted input in the username of a MongoDB URI with...

EUVD-2026-27838

The MongoDB C Driver's Cyrus SASL integration performs unsafe string copying during username canonicalization, enabling a heap buffer overflow before any authentication or network traffic. This may be triggered by passing untrusted input in the username of a MongoDB URI with authMechanism=GSSAPI...

Buffer Overflow

Overview Affected versions of this package are vulnerable to Buffer Overflow via unsafe string copying in the canonicalization process. An attacker can execute arbitrary code or cause a denial of service by supplying a specially crafted username in the MongoDB URI with authMechanism=GSSAPI before...
