CVE-2026-89012 (CVSS 6.5)

Description

Dolibarr 24.0.0 before 24.0.1 contains a case-sensitive denylist bypass vulnerability in the sqlfilters API query parameter that allows authenticated attackers to recover protected database fields by supplying uppercase variants of denylist-protected field names. Attackers can exploit the case-insensitive database column resolution against the case-sensitive denylist check in the core library to use prefix-matching predicates as a boolean oracle and extract full password hashes for any user account, including administrators.
