CVE-2026-85990 · Leantime: Any Authenticated User Can Self-Escalate to Admin via Unauthorized JSON-RPC Methods

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

Leantime is an open source project management system. Prior to 3.10.0, for the provisionally grouped account-creation and plugin-management surfaces, Leantime's JSON-RPC dispatcher in app/Domain/Api/Controllers/Jsonrpc.php exposes public API service methods, while PermissionEnforcer::enforce allows methods that lack a RequiresPermission attribute. A low-privilege authenticated user with an ordinary browser session can send the required X-Requested-With: XMLHttpRequest header and call leantime.rpc.api.api.createApiKeyWithProjects, which reaches Api::createApiKeyWithProjects, with an attacker-chosen role to create an interactive administrator account. The same missing per-method authorization exposes Plugins::installPlugin, Plugins::enablePlugin, Plugins::disablePlugin, and Plugins::removePlugin to ordinary authenticated users, permitting unauthorized plugin management. The complete provisionally grouped issue is fixed in version 3.10.0.
