Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4120 in the wild and no public exploit code.\n\nAffected product: bplugins Info Cards – Add Text and Media in Card Layouts. 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-2026-4120/ (Markdown: https://insights.sbomify.com/CVE-2026-4120/index.md)","id":"CVE-2026-4120","markdown":"https://insights.sbomify.com/CVE-2026-4120/index.md","name":"CVE-2026-4120","record":{"aliases":["GHSA-m6j6-gfjm-gh8m"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject JavaScript via block attributes to execute arbitrary scripts in victim browsers.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Info Cards – Add Text and Media in Card Layouts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'btnUrl' parameter within the Info Cards block in all versions up to, and including, 2.0.7. This is due to insufficient input validation on URL schemes, specifically the lack of javascript: protocol filtering. The block's render.php passes all attributes as JSON to the frontend via a data-attributes HTML attribute using esc_attr(wp_json_encode()), which prevents HTML attribute injection but does not validate URL protocols within the JSON data. The client-side view.js then renders the btnUrl value directly as an href attribute on anchor elements without any protocol sanitization. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject javascript: URLs that execute arbitrary web scripts when a user clicks the rendered button 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":"Info Cards \u003c= 2.0.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via Block Attributes","id":"CVE-2026-4120","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Kcaptcha \u003c= 1.0.1 - Cross-Site Request Forgery to Settings Update","id":"CVE-2026-4121"},"packages":[],"prev":{"headline":"Missing authorization in Create DB Tables","id":"CVE-2026-4119"},"products":["Info Cards – Add Text and Media in Card Layouts"],"published":"2026-03-19","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":"2026-04-08","vendors":["bplugins"]},"summary":"Authenticated attackers can inject JavaScript via block attributes to execute arbitrary scripts in victim browsers.","url":"https://insights.sbomify.com/CVE-2026-4120/"}
