Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4245 in the wild and no public exploit code.\n\nAffected product: metaphorcreations Post Duplicator. 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-2026-4245/ (Markdown: https://insights.sbomify.com/CVE-2026-4245/index.md)","id":"CVE-2026-4245","markdown":"https://insights.sbomify.com/CVE-2026-4245/index.md","name":"CVE-2026-4245","record":{"aliases":["GHSA-53vg-j9w4-c9v9"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated contributors can bypass editorial review to publish scheduled or private posts and duplicate restricted post types in the Post Duplicator plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"The Post Duplicator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.0.11. This is due to the `duplicate_post_permissions()` permission callback only verifying the `duplicate_posts` capability without checking whether the requesting user holds `publish_posts` or other status-gated capabilities. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicate posts with `future` (scheduled, auto-publishes) or `private` status, bypassing editorial review. Additionally, the REST endpoint does not enforce administrator-configured post-type duplication restrictions, allowing duplication of post types that have been explicitly disabled.","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":"Post Duplicator \u003c= 3.0.11 - Authorization Bypass to Authenticated (Contributor+) Post Duplication","id":"CVE-2026-4245","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"ElementsKit Pro \u003c= 4.10.1 - Unauthenticated Stored Cross-Site Scripting via 's' Parameter","id":"CVE-2026-4246"},"packages":[],"prev":{"headline":"Missing authorization in Post Duplicator","id":"CVE-2026-4244"},"products":["Post Duplicator"],"published":"2026-08-22","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":"2026-08-24","vendors":["metaphorcreations"]},"summary":"Authenticated contributors can bypass editorial review to publish scheduled or private posts and duplicate restricted post types in the Post Duplicator plugin.","url":"https://insights.sbomify.com/CVE-2026-4245/"}
