CVE-2026-106434
Description
A flaw was found in MongoDB libmongocrypt. When processing an unrecognized encrypted payload during explicit decryption, the library returns the data unchanged instead of generating a decryption error. An attacker capable of modifying stored encrypted fields, such as a compromised database server or network intermediary, can supply arbitrary data. As a result, the affected application mistakenly treats the raw data as valid decrypted plaintext, leading to data integrity issues.
