Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-75836 exists.\n\nAffected product: getgrav grav. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-75836/ (Markdown: https://insights.sbomify.com/CVE-2026-75836/index.md)","id":"CVE-2026-75836","markdown":"https://insights.sbomify.com/CVE-2026-75836/index.md","name":"CVE-2026-75836","record":{"aliases":["GHSA-cx7m-jmr8-28mw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS API plugin","requires_auth":"low_privilege","summary":"Authenticated users with basic API access can bypass authorization checks to execute privileged menubar actions in the Grav API plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Grav API Plugin before 1.0.14 Missing Authorization","id":"CVE-2026-75836","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Grav before 2.0.14 Privilege Escalation via Group Access Field","id":"CVE-2026-75837"},"packages":[],"prev":{"headline":"Grav API Plugin before 1.0.14 Missing Authorization","id":"CVE-2026-75835"},"products":["grav"],"published":"2026-08-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-18","vendors":["getgrav"]},"summary":"Authenticated users with basic API access can bypass authorization checks to execute privileged menubar actions in the Grav API plugin.","url":"https://insights.sbomify.com/CVE-2026-75836/"}
