Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4063 in the wild and no public exploit code.\n\nAffected product: wpzoom Social Icons Widget \u0026 Block – Social Media Icons \u0026 Share Buttons. 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-2026-4063/ (Markdown: https://insights.sbomify.com/CVE-2026-4063/index.md)","id":"CVE-2026-4063","markdown":"https://insights.sbomify.com/CVE-2026-4063/index.md","name":"CVE-2026-4063","record":{"aliases":["GHSA-5xh8-vh3c-9fxf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated subscribers can create sharing configurations that inject social buttons into all posts due to missing capability checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The Social Icons Widget \u0026 Block by WPZOOM plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check in the add_menu_item() method hooked to admin_menu in all versions up to, and including, 4.5.8.

This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger the creation of a published wpzoom-sharing configuration post with default sharing button settings, which causes social sharing buttons to be automatically injected into all post content on the frontend via the the_content filter.","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":"Missing authorization in Social Icons Widget \u0026 Block – Social Media Icons \u0026 Share Buttons","id":"CVE-2026-4063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Missing authorization in PowerShell Universal","id":"CVE-2026-4064"},"packages":[],"prev":{"headline":"Geo Mashup \u003c= 1.13.18 - Unauthenticated Time-Based SQL Injection via 'object_ids' Parameter","id":"CVE-2026-4062"},"products":["Social Icons Widget \u0026 Block – Social Media Icons \u0026 Share Buttons"],"published":"2026-03-13","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":["wpzoom"]},"summary":"Authenticated subscribers can create sharing configurations that inject social buttons into all posts due to missing capability checks.","url":"https://insights.sbomify.com/CVE-2026-4063/"}
