{"id":"CVE-2026-85990","summary":"Leantime: Any Authenticated User Can Self-Escalate to Admin via Unauthorized JSON-RPC Methods","details":"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.","aliases":["GHSA-54mm-6729-r5wp"],"modified":"2026-10-15T02:47:45.519298628Z","published":"2026-10-13T16:15:09.529Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85990.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/Leantime/leantime/releases/tag/v3.10.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85990.json"},{"type":"ADVISORY","url":"https://github.com/Leantime/leantime/security/advisories/GHSA-54mm-6729-r5wp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85990"},{"type":"FIX","url":"https://github.com/Leantime/leantime/commit/5605e5ee86bbd01acb85c6b5d8fb337faf8bcf02"},{"type":"FIX","url":"https://github.com/Leantime/leantime/commit/7ebf7a9517e2aaa05ec15b8130ab1841a4bde43e"},{"type":"FIX","url":"https://github.com/Leantime/leantime/pull/3583"},{"type":"FIX","url":"https://github.com/Leantime/leantime/pull/3797"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/leantime/leantime","events":[{"introduced":"0"},{"fixed":"5605e5ee86bbd01acb85c6b5d8fb337faf8bcf02"},{"fixed":"7ebf7a9517e2aaa05ec15b8130ab1841a4bde43e"},{"fixed":"d147c3a3ce3037c35fa9cfc4e43069e3c55ed31c"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.10.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v3.9.5","v3.9.4","v3.9.3","v3.9.2","v3.9.1","v3.9.0","v3.8.0","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.2","latest","v3.6.1","v3.6.0","v3.5.12","v3.5.11","v3.5.10","v3.5.8","v3.5.7","v3.5.6","v3.5.5","v3.5.4","v3.5.3","v3.5.2","v3.5.1","v3.4.12","v3.4.11","v3.4.10","v3.4.9","v3.4.7","v3.4.6","v3.4.5","v3.4.4","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.3","v3.3.1","v3.3.0","v3.2.1","v3.2.0","v3.2.0-beta-2","v3.2.0-beta","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0-beta","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.1","v3.0.2","v3.0.0","v3.0.0-beta","v2.4.8","v2.4.7","v2.4.5","v2.4.4","v2.4.3","v2.4.2","v2.4.1","v2.4-beta-8","v2.4","v2.4-beta-7","v2.4-beta","v2.3.27","v2.3.26","v2.3.24","v2.3.25","v2.3.23","v2.3.22","v2.3.21","v2.3.20","v2.3.19","v2.3.18","v2.3.17","v2.3.16","v2.3.15","v2.3.14","v2.3.13","v2.3.12","v2.3.11","v2.3.10","v2.3.9","v2.3.8","v2.3.7","v2.3.6","v2.3.5","v2.3.4","v2.3.3","v2.3.2","v2.3.1-beta","v2.3.0-beta","v2.3-beta","v2.2.11","v2.2.10","v2.2.9","v2.2.8","v2.2.7","v2.2.6","v2.2.5","v2.2.4","v2.2.3","v2.2.0","v2.2.2","v2.2.1","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1","v2.1-beta6","v2.1-beta5","v2.1-beta4b","v2.1-beta3","v2.0.14","v2.1-beta2","v2.1-beta","v2.0.13","v2.0.12","v2.0.11","v2.0.10","v2.0.9","v2.0.8","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0","v0.9.5-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85990.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
