Stored XSS via unfiltered REST API fields

Published Sep 20, 2023 · Updated Jul 9, 2026

Stored XSS in the REST API module in Dolibarr ERP CRM 17.0.1 and earlier allows remote authenticated users to execute script in other users' browsers. REST API POST and PUT body fields bypass the analyseVarsForSqlAndScriptsInjection and testSqlAndScriptInject input checks in htdocs/main.inc.php. The module must be enabled, the attacker needs an API key and object-write permission, and another user must view the stored content.
