Auth bypass in Dolibarr
CVE-2026-71510
Dolibarr before 24.0.0 contains a SQL injection vulnerability in the users REST API that allows authenticated attackers with user-read rights to extract sensitive data by splicing unsanitized filter parameters into SQL WHERE clauses without column restrictions. Attackers can perform binary search on numeric fields and LIKE prefix iteration on string fields to recover salary figures and password verifiers omitted from normal API responses, while raw database error messages in the same endpoint enable column name enumeration.
