Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4086 in the wild and no public exploit code.\n\nAffected product: newbiesup WP Random Button. 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-2026-4086/ (Markdown: https://insights.sbomify.com/CVE-2026-4086/index.md)","id":"CVE-2026-4086","markdown":"https://insights.sbomify.com/CVE-2026-4086/index.md","name":"CVE-2026-4086","record":{"aliases":["GHSA-x5f6-m38m-6rp5"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject arbitrary scripts via shortcode attributes, leading to code execution 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 WP Random Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'cat', 'nocat', and 'text' shortcode attributes of the 'wp_random_button' shortcode in all versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the random_button_html() function directly concatenates the 'cat' and 'nocat' parameters into HTML data-attributes without esc_attr(), and the 'text' parameter into HTML content without esc_html(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","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":"WP Random Button \u003c= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'cat' Shortcode Attribute","id":"CVE-2026-4086","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Pre* Party Resource Hints \u003c= 1.8.20 - Authenticated (Subscriber+) SQL Injection via 'hint_ids' Parameter","id":"CVE-2026-4087"},"packages":[],"prev":{"headline":"Cross-site scripting in Easy Social Photos Gallery – MIF","id":"CVE-2026-4085"},"products":["WP Random Button"],"published":"2026-03-21","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":["newbiesup"]},"summary":"Authenticated attackers can inject arbitrary scripts via shortcode attributes, leading to code execution in victim browsers.","url":"https://insights.sbomify.com/CVE-2026-4086/"}
