Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16273 exists.\n\nAffected product: Unknown Narrative Publisher. 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-2026-16273/ (Markdown: https://insights.sbomify.com/CVE-2026-16273/index.md)","id":"CVE-2026-16273","markdown":"https://insights.sbomify.com/CVE-2026-16273/index.md","name":"CVE-2026-16273","record":{"aliases":["GHSA-26m8-g7wc-p86g"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Contributors can inject JavaScript via post meta fields, leading to code execution in the browsers of higher-privileged users viewing the post.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Narrative Publisher WordPress plugin through 1.0.7 does not restrict write access to a REST-exposed post meta field or escape it when rendering, allowing users with contributor-level access and above to store JavaScript that executes in the browser of any higher-privileged user who views the affected post.","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":"Narrative Publisher \u003c= 1.0.7 - Contributor+ Stored XSS via narrative_post_script Post Meta","id":"CVE-2026-16273","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Classified Listing \u003c 5.4.4 - Contributor+ Unpublished Post Content Disclosure via rtcl_block_css_get_posts","id":"CVE-2026-16274"},"packages":[],"prev":{"headline":"Client IP Spoofing via Untrusted HTTP Headers in PayTR's PayTR Virtual Pos iFrame API WHMCS Module","id":"CVE-2026-16272"},"products":["Narrative Publisher"],"published":"2026-08-02","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-03","vendors":["Unknown"]},"summary":"Contributors can inject JavaScript via post meta fields, leading to code execution in the browsers of higher-privileged users viewing the post.","url":"https://insights.sbomify.com/CVE-2026-16273/"}
