An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-18843 in the wild and no public exploit code.\n\nAffected product: The Beaver Builder Team Beaver Builder Plugin (Starter Version). 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-2026-18843/ (Markdown: https://insights.sbomify.com/CVE-2026-18843/index.md)","id":"CVE-2026-18843","markdown":"https://insights.sbomify.com/CVE-2026-18843/index.md","name":"CVE-2026-18843","record":{"aliases":["GHSA-grcg-2g4r-q84p"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject arbitrary scripts via the no_results_message parameter, requiring user interaction to execute.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/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 Beaver Builder Plugin (Starter Version) plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'no_results_message' node_preview Parameter in all versions up to, and including, 2.11.0.1 due to insufficient input sanitization and output escaping.
