Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84909 in the wild and no public exploit code.\n\nAffected product: smub Custom Twitter Feeds – A Tweets Widget or X Feed Widget. 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-2026-84909/ (Markdown: https://insights.sbomify.com/CVE-2026-84909/index.md)","id":"CVE-2026-84909","markdown":"https://insights.sbomify.com/CVE-2026-84909/index.md","name":"CVE-2026-84909","record":{"aliases":["GHSA-9fp7-mwxw-94ff"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated contributors can inject arbitrary scripts via the buttoncolor shortcode attribute in the Custom Twitter Feeds plugin.","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 Custom Twitter Feeds – A Tweets Widget or X Feed Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'buttoncolor' Shortcode Attribute in all versions up to, and including, 2.8.0 due to insufficient input sanitization and output escaping.
