An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-77788 in the wild and no public exploit code.\n\nAffected product: Unknown Rank Math SEO. 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-2026-77788/ (Markdown: https://insights.sbomify.com/CVE-2026-77788/index.md)","id":"CVE-2026-77788","markdown":"https://insights.sbomify.com/CVE-2026-77788/index.md","name":"CVE-2026-77788","record":{"aliases":["GHSA-4vrc-p2pf-p4qj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Authors can overwrite arbitrary post and user metadata, potentially escalating privileges or modifying data belonging to higher-privileged users.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The Rank Math SEO  WordPress plugin before 1.0.277 does not verify that the metadata row being updated belongs to the object the user was authorised against, allowing users with the Author role and above to overwrite arbitrary post and user metadata, including that belonging to higher-privileged users.","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":"Rank Math SEO \u003c 1.0.277 - Author+ Arbitrary Post and User Metadata Overwrite via updateSchemas","id":"CVE-2026-77788","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":"Stripe Payment Forms by WP Full Pay \u003c 8.5.1 - Cross-Customer Subscription Modification via IDOR","id":"CVE-2026-77789"},"packages":[],"prev":{"headline":"Rank Math SEO \u003c 1.0.277 - Author+ Term Metadata Update and Cross-Object Post Title Overwrite via updateMetaBulk","id":"CVE-2026-77787"},"products":["Rank Math SEO"],"published":"2026-09-02","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":"partial"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Unknown"]},"summary":"Authors can overwrite arbitrary post and user metadata, potentially escalating privileges or modifying data belonging to higher-privileged users.","url":"https://insights.sbomify.com/CVE-2026-77788/"}
