An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-84899 in the wild and no public exploit code.\n\nAffected product: Unknown VikWidgetsLoader. 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-2026-84899/ (Markdown: https://insights.sbomify.com/CVE-2026-84899/index.md)","id":"CVE-2026-84899","markdown":"https://insights.sbomify.com/CVE-2026-84899/index.md","name":"CVE-2026-84899","record":{"aliases":["GHSA-gff8-vmj9-6526"],"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":"high_privilege","summary":"Contributors can inject JavaScript via Gutenberg block attributes, leading to code execution in admin browsers and potential account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The VikWidgetsLoader  WordPress plugin before 1.12.0 does not sanitise or escape a block attribute before outputting it inside an inline script, allowing users with the Contributor role to store arbitrary JavaScript that executes in the browser of any user viewing the affected post, including the administrator who reviews the pending submission.","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":"VikWidgetsLoader \u003c 1.12.0 - Contributor+ Stored XSS via Gutenberg Block class_suffix","id":"CVE-2026-84899","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"HP ThinPro 8.1 SP10 and ThinPro 9 SP3 Security Updates","id":"CVE-2026-84900"},"packages":[],"prev":{"headline":"Eventin \u003c 4.1.21 - Contributor+ LFI via Event Layout Meta","id":"CVE-2026-84898"},"products":["VikWidgetsLoader"],"published":"2026-09-05","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":"2026-09-06","vendors":["Unknown"]},"summary":"Contributors can inject JavaScript via Gutenberg block attributes, leading to code execution in admin browsers and potential account takeover.","url":"https://insights.sbomify.com/CVE-2026-84899/"}
