Title
Heap out-of-bounds read via corrupt nested BSON in field path error message
Summary
An out-of-bounds read in the BSON decoding component of the MongoDB PHP driver may allow an unauthenticated party who supplies specially formed input to have a small amount of adjacent process memory copied into an error message that is returned to application code. This may result in unintended disclosure of limited memory contents.

Title
Arbitrary command execution via shell-expanded connection string in Launch MongoDB Shell terminal
Summary
A component of the MongoDB extension for Visual Studio Code does not neutralize special characters in a connection string before that value is placed into a command line the extension composes for an integrated terminal. An unauthenticated remote unauthorized-user who persuades a developer to accept a user-supplied connection target, and then to open the extension's shell feature, can place characters of the unauthorized-user’s choosing into that command line. No privileges on the developer's machine are required, but several user actions are. The confirmation the developer sees does not display the supplied text.

Title
Silent field truncation via unchecked int cast of huge JSON string values in JSON-to-BSON parser
Summary
An incorrect numeric conversion in the JSON parsing component of the MongoDB C Driver's BSON library may cause an unusually large text value to be silently shortened, or the corresponding field to be omitted, while the parsing operation still reports success and returns no error. An unauthenticated party who can supply the input processed by an application that uses this component may cause that application to hold data that does not match what was submitted, which may result in unintended alteration of data.

Title
Heap corruption via OCSP request double free from crafted multi-URL certificate in TLS client
Summary
A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already trusts. During the handshake, specially formed certificate data can cause the same heap object to be released twice. An unauthenticated party acting as the trusted endpoint may cause the connecting client application to terminate unexpectedly.

Title
Heap write primitive via size round-up wrap during JSON parsing on 32-bit builds
Summary
An integer wraparound in an allocation size calculation in the BSON library's JSON parsing code can cause a buffer to be released while a following copy operation still writes through the stale pointer. On builds where sizes are 32 bits, an unauthenticated party able to supply a sufficiently large JSON input to an application that links the library may cause that application to terminate unexpectedly, resulting in denial of service.

Title
BSON element injection via NUL-embedded document keys in builder append
Summary
An incorrect numeric type conversion in the BSON document building component of the MongoDB C++ Driver may cause a length value to be interpreted incorrectly. When an application supplies an extremely large, non-terminated field name to the builder, the library may read memory outside the intended buffer and terminate the calling process. No authentication is required, but the calling application must pass the oversized name in a specific form.

Title
Heap overflow via truncated base64 encoding of binary fields in length-limited JSON output
Summary
A memory-handling error in the BSON-to-JSON conversion helpers of the MongoDB C Driver can write a small number of bytes past the end of a heap buffer when a binary field is encoded and the output is cut short at a caller-configured length limit. A party who supplies the document content, with no privileges on the application that links the driver, may cause a small amount of data outside the intended buffer to be altered.

Title
Persistent client crash loop via undersized FLE2 insert-update ciphertext in decryption path
Summary
Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it, or able to control the responses the application receives, may cause that application to stop running.

Title
Heap over-read or silent misparse via 32-bit truncation of JSON length in BSON JSON parser
Summary
A numeric truncation weakness exists in the JSON parsing component of the MongoDB C++ Driver's BSON library. An actor who controls the text that an embedding application hands to the library's public JSON parsing interface, when that text is very large, can cause the library to read memory beyond the supplied buffer and return it to the caller, to silently accept only part of the input as a complete document, or to terminate the process. No MongoDB server, credentials, or non-default configuration is required; the effect is confined to the process that uses the library.

Title
MongoDB BI Connector ODBC Driver Memory-Safety Issue When Parsing Oversized LIMIT Values
Summary
An application using the MongoDB BI Connector ODBC Driver may encounter a memory-safety issue when a submitted SQL statement contains an unusually long run of digits following a LIMIT clause. The issue occurs only on connections where the driver's optional prefetch setting is enabled, and stems from the driver copying the digit sequence into a fixed-size internal buffer without checking its length. A user able to influence the numeric portion of a LIMIT clause could cause the hosting application process to terminate unexpectedly or corrupt adjacent memory in that process.

Title
BI Connector ODBC Driver Improper Bounds Checking on Cursor Name Leading to Memory Corruption
Summary
A user able to submit SQL through an application using the MongoDB Connector for BI ODBC driver can supply a positioned-cursor statement whose cursor name exceeds the size of an internal fixed-length buffer. Because the name length is not bounded before the driver builds its diagnostic message, memory adjacent to that buffer is overwritten with user-supplied content. This can terminate the hosting application process and may allow unintended code to run within it.

Title
MongoDB Connector for BI Unbounded Authentication Negotiation Leading to Connection Exhaustion
Summary
A network-reachable client that has not yet authenticated can hold a MongoDB Connector for BI authentication session open indefinitely by beginning a SASL-based login exchange and then declining to complete it. Because the negotiation loop had no overall time bound and the read from the client had no deadline, each such session retains a worker, a client connection slot, and its associated backend database connections until the process is restarted. Repeated use of this behavior can consume the configured connection capacity and prevent legitimate users from establishing new sessions.

Title
BI Connector Optional Client Certificate Verification Allows Unauthenticated Connections
Summary
When mongosqld is configured with a client certificate authority file, the listener requests a client certificate during the TLS handshake but does not require one, so a client that presents no certificate is still accepted. In deployments that rely on client certificates as the sole means of identifying users, a remote party with network access to the listener can therefore establish a session and read the MongoDB data exposed through the connector.

Title
MongoDB Connector for BI Improper Error Handling of Log Write Failures May Cause Loss of SQL Service
Summary
An unauthenticated party able to reach the port of a MongoDB Connector for BI (mongosqld) instance may generate enough routine connection log activity to exhaust the storage backing the configured log path. When a log write or log rotation operation subsequently fails, the resulting error is not handled and the shared mongosqld process ends, ending service for all connected SQL clients. The process continues to end on startup until an operator restores available storage, and the diagnostic message explaining the condition is not recorded.

Title
MongoDB Connector for BI Improper Error Handling During Schema Sampling May Cause Loss of SQL Service
Summary
A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling.

Title
MongoDB Connector for BI Unescaped Object Names in Generated SHOW CREATE Output
Summary
In MongoDB Connector for BI, MongoDB object names such as collection, field, and index names are placed into the quoted identifiers of the DDL text returned by SHOW CREATE statements without escaping the identifier delimiter. A user with permission to write to a sampled MongoDB collection can choose a name that closes the quoted identifier early, so that additional SQL text becomes part of the generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.

Title
MongoDB Connector for BI Incomplete Escaping of Stored Metadata in Generated SHOW CREATE Output
Summary
In MongoDB Connector for BI, the description text of a collection's JSON schema validator is incorporated into the comment text of the DDL returned by SHOW CREATE statements without complete escaping of backslash characters. A user with permission to modify a collection's schema validator, in deployments configured to build their SQL schema from those validators, can cause additional SQL text to be embedded in that generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.

Title
MongoSQL Transition Readiness Tool Improper Output Encoding in Generated HTML Reports
Summary
The MongoSQL Transition Readiness Tool writes query text and user names read from BI Connector log files into its generated HTML report without encoding them for that output context. A user able to issue queries through the BI Connector can influence log content so that markup supplied in a query is interpreted by the browser when an operator later generates and opens the report, which may disclose other users' logged query text and user names to an external party or present misleading content to the operator. Generating a report over logs containing the affected entries and opening that report in a browser is required.

Title
MongoSQL Transition Readiness Tool Improper Neutralization of Formula Elements in Generated Reports
Summary
The MongoSQL Transition Readiness Tool writes database and collection names into its generated CSV reports without neutralizing leading characters that spreadsheet applications treat as formulas. A user with write privileges on the cluster can choose a namespace name that is later evaluated as a formula when an operator opens the generated report in a spreadsheet application, which may result in unintended disclosure of report contents or execution of external content on the operator's workstation. Generating a report for the affected namespace and opening it in a spreadsheet application is required.

Title
KMS master key exposure via unredacted credential serialization in driver settings string
Summary
A weakness in the client-side encryption configuration surface of the MongoDB C# Driver causes sensitive key-management credential material supplied by the application to be reproduced verbatim in the driver's human-readable diagnostic representation of its client settings, instead of being masked as other secret fields are. A party able to read the application's logs, diagnostic output, or a process memory dump may thereby recover the plaintext credentials and use them to decrypt protected field data.

Title
Connection-option injection via unescaped settings in the canonical MongoDB URL builder
Summary
Improper neutralization of delimiters in connection-URL construction allows connection-option injection in the MongoDB C# Driver. When an application passes untrusted text into the driver's connection-URL builder and round-trips the builder back into a client configuration, the untrusted text is serialized without neutralizing the URL/option delimiters and is then re-parsed as authoritative connection options. A low-privileged user of such an application can thereby introduce or suppress security-relevant connection settings.

Title
NoSQL injection via array replacement bypassing update shape validation in driver write path
Summary
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, loosely-typed input as a replacement value therefore allows that input to be interpreted by the database as update logic rather than as data, executing under the application's own database credentials. Applications using strongly-typed document mappings are not affected.

CVE-2026-81527 (GCVE-0-2026-81527)

Title
NoSQL injection via unquoted constant GroupBy keys in LINQ pipeline translation
Summary
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 values are not properly escaped before the resulting query is transmitted to the database, so portions of the value may be interpreted by the database as query logic rather than as data. A user able to supply values that an application incorporates into an affected query may thereby cause unintended data to be returned or query results to be altered.

Title
Cross-database write redirection via unvalidated dotted database name in bulk write namespaces
Summary
The MongoDB Rust Driver does not neutralize special characters in a caller-supplied target identifier before embedding it in the request it sends to the server. An actor able to influence that identifier in an application using the driver may cause write operations to be applied to an unintended target within the same deployment using the application's own credentials. This may result in unauthorized modification of data belonging to another logical boundary enforced by the application.

Title
Cross-tenant database retargeting via dot/NUL injection in namespace strings in the PHP Driver
Summary
The MongoDB client library for PHP does not sufficiently sanitize special elements in application-supplied namespace identifiers before using them to construct the target namespace for database operations. An application that incorporates untrusted text into these identifiers may have operations silently directed at a different storage location than the one the application intended.

Title
Cross-tenant database retargeting via dot/NUL injection in namespace strings in the C Driver
Summary
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 operations directed at a resource other than the one intended.

Title
Cross-tenant database retargeting via dot/NUL injection in namespace strings in libmongocrypt
Summary
A missing input-validation issue in MongoDB libmongocrypt's automatic-encryption context setup allows a caller-supplied database identifier to be accepted without sanitization. The resulting impact is limited to incorrect schema selection, which may lead to limited disclosure or modification of information handled by the application.
