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.","state":0,"publishedAt":"2026-10-13T16:15:09.529+00:00","modifiedAt":"2026-10-16T22:08:17.288+00:00","affected":[{"ecosystem":"Vendor product","name":"leantime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Leantime\",\n                    \"product\": \"leantime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.10.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/Leantime/leantime/security/advisories/GHSA-54mm-6729-r5wp","https://github.com/Leantime/leantime/pull/3583","https://github.com/Leantime/leantime/pull/3797","https://github.com/Leantime/leantime/commit/5605e5ee86bbd01acb85c6b5d8fb337faf8bcf02","https://github.com/Leantime/leantime/commit/7ebf7a9517e2aaa05ec15b8130ab1841a4bde43e","https://github.com/Leantime/leantime/releases/tag/v3.10.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-85990","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-85990","identifiers":["CVE-2026-85990"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
