The dispatcher does not enforce authorization before invoking service-layer methods, allowing an authenticated user to call methods or act on resources outside their intended permissions. For example, the editOwn method accepts a user-supplied user ID without verifying that it belongs to the caller, allowing an attacker to modify another user's account and set a new password, resulting in account takeover. This vulnerability is distinct from CVE-2026-59712 and CVE-2026-15509 because the root cause is the lack of centralized authorization enforcement in the JSON-RPC dispatcher rather than the behavior of an individual exposed method.","state":"PUBLISHED","assigner":"certcc","published_at":"2026-08-19 20:17:24","updated_at":"2026-08-19 20:17:24"},"problem_types":["CWE-862 Missing Authorization","CWE-200 Exposure of Sensitive Information to an Unauthorized Actor","CWE-639 Authorization Bypass Through User-Controlled Key"],"metrics":[],"references":[{"url":"https://vokecyber.com/blog/leantime-jsonrpc-editown-account-takeover","name":"https://vokecyber.com/blog/leantime-jsonrpc-editown-account-takeover","refsource":"cret@cert.org","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://leantime.io/unlocking-leantimes-power-a-guide-to-the-json-rpc-api/","name":"https://leantime.io/unlocking-leantimes-power-a-guide-to-the-json-rpc-api/","refsource":"cret@cert.org","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://vokecyber.com/research/leantime-jsonrpc-editown-account-takeover","name":"https://vokecyber.com/research/leantime-jsonrpc-editown-account-takeover","refsource":"cret@cert.org","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-76647","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76647","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"Leantime","product":"JSON-RPC API","version":"affected 3.9.0 custom","platforms":[]}],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":{"cve_year":"2026","cve_id":"76647","cve":"CVE-2026-76647","epss":"0.001650000","percentile":"0.061890000","score_date":"2026-08-20","updated_at":"2026-08-21 00:13:52"},"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"product":"JSON-RPC API","vendor":"Leantime","versions":[{"lessThanOrEqual":"3.9.0","status":"affected","version":"0","versionType":"custom"}]}],"descriptions":[{"lang":"en","value":"Leantime JSON-RPC API through version 3.9.0 contains a missing authorization vulnerability in the JSON-RPC dispatcher in app/Domain/Api/Controllers/Jsonrpc.php.
