Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3896 in the wild and no public exploit code.\n\nAffected product: Livemesh SiteOrigin Widgets. 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-2026-3896/ (Markdown: https://insights.sbomify.com/CVE-2026-3896/index.md)","id":"CVE-2026-3896","markdown":"https://insights.sbomify.com/CVE-2026-3896/index.md","name":"CVE-2026-3896","record":{"aliases":["GHSA-6jw7-72vv-cg3r"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated subscribers can inject malicious scripts via missing authorization checks, leading to code execution and potential privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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-862","name":"Missing Authorization"}],"description":"The Livemesh SiteOrigin Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `lsow_admin_ajax` AJAX action in all versions up to, and including, 3.9.2 due to missing authorization checks and insufficient input sanitization.
