CVE-2026-81525

CVE-2026-81525 is a cross-tenant database retargeting vulnerability in the MongoDB client library for PHP (mongo-php-library and mongo-php-driver). The root cause is insufficient sanitization of dot and NUL characters in application-supplied namespace identifiers, allowing an attacker with low pr...

CVE-2026-81525 Cross-tenant database retargeting via dot/NUL injection in namespace strings in the PHP Driver

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...

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-2026-81523 Cross-tenant database retargeting via dot/NUL injection in namespace strings in libmongocrypt

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...

CVE-2026-81523

A missing input-validation flaw in MongoDB libmongocrypt 's automatic-encryption context setup allows a caller-supplied database identifier to be accepted without sanitization. The CVELIST record further specifies the mechanism as dot/NUL injection in namespace strings, enabling cross-tenant data...

CVE-2026-81523 Cross-tenant database retargeting via dot/NUL injection in namespace strings in libmongocrypt

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...

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...

Cross-database write retargeting via unvalidated dotted database name in Client.BulkWrite in the MongoDB Go Driver

The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name...

CVE-2026-81521

CVE-2026-81521 affects the MongoDB Go Driver's Client.BulkWrite API . When a caller-supplied database name contains a reserved separator character (dot) that is not escaped before being used to build the target namespace, a write operation can be redirected to an unintended database and collectio...

The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name...

CVE-2026-58439

A flaw was found in Gitea. This vulnerability allows an attacker to bypass branch protection by retargeting a Pull Request PR that has a stale 'official' approval flag. This could lead to unauthorized code being merged into a protected branch, compromising code integrity. Mitigation Mitigation fo...
