{"apiVersion":"1.0","identifier":"CVE-2026-76647","description":"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. 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.","publishedAt":"2026-08-19T20:17:24","lastModifiedAt":"2026-08-27T17:20:17","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76647","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00375,"riskScore":0.91,"affectedProduct":"Leantime","affectedVersions":"<=3.9.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76647","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76647","en":"https://www.redsauce.net/en/cves/CVE-2026-76647","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76647","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76647","de":"https://www.redsauce.net/de/cves/CVE-2026-76647","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76647","el":"https://www.redsauce.net/el/cves/CVE-2026-76647"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76647"}}
