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...
