An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-89001 in the wild and no public exploit code.\n\nAffected product: Unknown WPeMatico RSS Feed Fetcher. 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-2026-89001/ (Markdown: https://insights.sbomify.com/CVE-2026-89001/index.md)","id":"CVE-2026-89001","markdown":"https://insights.sbomify.com/CVE-2026-89001/index.md","name":"CVE-2026-89001","record":{"aliases":["GHSA-m259-ww4h-6j9q"],"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":"high_privilege","summary":"Contributors can publish posts and spoof authors, including administrators, due to missing authorization checks in the WPeMatico RSS Feed Fetcher plugin.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"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-269","name":"Improper Privilege Management"}],"description":"The WPeMatico RSS Feed Fetcher WordPress plugin before 2.8.27 does not verify that a user running a feed campaign is permitted to publish content or to attribute posts to another account, allowing users with contributor-level access and above to publish posts live and set any registered user, including an administrator, as the post author.","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":"WPeMatico RSS Feed Fetcher \u003c 2.8.27 - Contributor+ Post Publication and Author Spoofing via Campaign Settings","id":"CVE-2026-89001","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WPeMatico RSS Feed Fetcher \u003c 2.8.26 - Contributor+ Stored XSS via Campaign Item Preview","id":"CVE-2026-89002"},"packages":[],"prev":{"headline":"WPeMatico RSS Feed Fetcher \u003c 2.8.27 - Contributor+ SSRF via Campaign Run","id":"CVE-2026-89000"},"products":["WPeMatico RSS Feed Fetcher"],"published":"2026-09-27","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":"2026-09-28","vendors":["Unknown"]},"summary":"Contributors can publish posts and spoof authors, including administrators, due to missing authorization checks in the WPeMatico RSS Feed Fetcher plugin.","url":"https://insights.sbomify.com/CVE-2026-89001/"}
