GHSA-8vwp-6h6c-hx6h on Cyberus Linux 26.05

Aliases: GHSA-8vwp-6h6c-hx6h, CVE-2026-84963

Packages: mongoc

Status: Resolved

Advisory Information

Impact

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.

Patches

Fixed in 1.30.9 and 2.5.2

Workarounds

Validate length of inputs before processing JSON.
