{"apiVersion":"1.0","identifier":"CVE-2026-75836","description":"The Grav API plugin (getgrav/grav-plugin-api, bundled with Grav-s admin-next/API stack) before 1.0.14 fails to enforce the authorize requirement in MenubarController::executeAction(). While the GET /menubar/items listing endpoint correctly filters menubar items via userPassesAuthorize(), the POST /api/v1/menubar/actions/{plugin}/{action} endpoint only checks the baseline api.access permission and never evaluates the authorize field a plugin registered for that action. Any authenticated caller with api.access can therefore invoke a privileged menubar action directly, bypassing the intended authorization. No plugin bundled with core Grav currently registers a privileged authorize handler, so on a stock install the impact is latent; the flaw affects any first- or third-party plugin relying on the documented authorize semantics.","publishedAt":"2026-08-18T12:19:33","lastModifiedAt":"2026-08-18T15:17:14","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75836","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00322,"riskScore":0.91,"affectedProduct":"Grav API plugin","affectedVersions":"<1.0.14","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75836","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75836","en":"https://www.redsauce.net/en/cves/CVE-2026-75836","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75836","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75836","de":"https://www.redsauce.net/de/cves/CVE-2026-75836","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75836","el":"https://www.redsauce.net/el/cves/CVE-2026-75836"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75836"}}
