## Technical details

The sqlfilters API parameter in Dolibarr 24.0.0 performs a case-sensitive denylist check against forbidden database field names, but the underlying database column resolution is case-insensitive, creating a bypass. An authenticated attacker can submit uppercase or mixed-case variants of protected field names (e.g., PASSWORD instead of password) to circumvent the denylist. By exploiting prefix-matching predicates as a boolean oracle, attackers can extract full password hashes for any user account. The vulnerability exists in htdocs/core/lib/functions.lib.php in the dolForgeSQLCriteriaCallback() function. The fix applies case-insensitive comparison to the denylist check by wrapping the operand in strtolower() before comparison.
