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."}],"source":{"advisory":"GHSA-54mm-6729-r5wp","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/Leantime/leantime/security/advisories/GHSA-54mm-6729-r5wp","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-16T22:07:42.946920Z","id":"CVE-2026-85990","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T22:08:17.288Z"}}]}}
