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-2026-84021 in the wild and no public exploit code.\n\nAffected product: Unknown Bold Page Builder. 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-2026-84021/ (Markdown: https://insights.sbomify.com/CVE-2026-84021/index.md)","id":"CVE-2026-84021","markdown":"https://insights.sbomify.com/CVE-2026-84021/index.md","name":"CVE-2026-84021","record":{"aliases":["GHSA-v5jf-q9wj-fxfx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Contributors can inject arbitrary scripts via URL fields in Bold Page Builder, leading to code execution when links are clicked.","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 Bold Page Builder WordPress plugin before 5.9.8 does not properly validate a link URL before outputting it in an HTML attribute, relying on a filter that can be evaded, allowing users with the Contributor role and above to inject arbitrary web scripts that execute when a user clicks the affected link.","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":"Bold Page Builder \u003c 5.9.8 - Contributor+ Stored XSS via bt_bb_button/bt_bb_headline/bt_bb_icon URL","id":"CVE-2026-84021","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Bold Page Builder \u003c 5.9.8 - Contributor+ Stored XSS via Multiple Shortcode Element Attributes","id":"CVE-2026-84022"},"packages":[],"prev":{"headline":"Windows Routing and Remote Access Service (RRAS) Elevation of Privilege Vulnerability","id":"CVE-2026-84020"},"products":["Bold Page Builder"],"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 arbitrary scripts via URL fields in Bold Page Builder, leading to code execution when links are clicked.","url":"https://insights.sbomify.com/CVE-2026-84021/"}
