An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-12426 in the wild and no public exploit code.\n\nAffected product: supercleanse Members – Membership \u0026 User Role Editor Plugin. 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-2026-12426/ (Markdown: https://insights.sbomify.com/CVE-2026-12426/index.md)","id":"CVE-2026-12426","markdown":"https://insights.sbomify.com/CVE-2026-12426/index.md","name":"CVE-2026-12426","record":{"aliases":["GHSA-5xr4-65q6-7jp8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can infer the existence, count, and content of restricted posts via a REST API pagination side channel in the Members plugin.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Members – Membership \u0026 User Role Editor Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.2.22 via the members_filter_protected_posts_for_rest.
