CVE-2026-81523  (opens in a new tab)

How to fix?

Upgrade Echo:latest libmongocrypt to version 1.13.2-1+deb13u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libmongocrypt package and not the libmongocrypt package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
