Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54842 in the wild and no public exploit code.\n\nAffected product: Royal MCP. 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-2026-54842/ (Markdown: https://insights.sbomify.com/CVE-2026-54842/index.md)","id":"CVE-2026-54842","markdown":"https://insights.sbomify.com/CVE-2026-54842/index.md","name":"CVE-2026-54842","record":{"aliases":["GHSA-7649-6hf2-rxrp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Attackers can bypass access controls in the Royal MCP WordPress plugin to perform unauthorized actions.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Missing Authorization vulnerability in Royal Plugins Royal MCP allows Exploiting Incorrectly Configured Access Control Security Levels.\n\nThis issue affects Royal MCP: from n/a through 1.4.25.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"WordPress Royal MCP plugin \u003c= 1.4.25 - Broken Access Control vulnerability","id":"CVE-2026-54842","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress MDTF plugin \u003c= 1.3.7 - SQL Injection vulnerability","id":"CVE-2026-54843"},"packages":[],"prev":{"headline":"WordPress Vitepos plugin \u003c= 3.4.2 - Sensitive Data Exposure vulnerability","id":"CVE-2026-54841"},"products":["Royal MCP"],"published":"2026-06-25","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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-25","vendors":["Royal Plugins"]},"summary":"Attackers can bypass access controls in the Royal MCP WordPress plugin to perform unauthorized actions.","url":"https://insights.sbomify.com/CVE-2026-54842/"}
