CVE-2025-1691

The MongoDB Shell may be susceptible to control character injection where an attacker with control of the mongosh autocomplete feature, can use the autocompletion feature to input and run obfuscated malicious text. This requires user interaction in the form of the user using tab to autocomplete text that is a prefix of the attackers prepared autocompletion. This issue affects mongosh versions prior to2.3.9.


The vulnerability is exploitable only when mongosh is connected to a cluster that is partially or fully controlled by an attacker.
