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-2026-40742 in the wild and no public exploit code.\n\nAffected product: Nelio AB Testing. 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-2026-40742/ (Markdown: https://insights.sbomify.com/CVE-2026-40742/index.md)","id":"CVE-2026-40742","markdown":"https://insights.sbomify.com/CVE-2026-40742/index.md","name":"CVE-2026-40742","record":{"aliases":["GHSA-h93w-324f-xffx"],"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":"Attackers can access sensitive data due to missing authorization checks in the Nelio AB Testing plugin for WordPress.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","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-862","name":"Missing Authorization"}],"description":"Missing Authorization vulnerability in Nelio Software Nelio AB Testing nelio-ab-testing allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Nelio AB Testing: from n/a through \u003c= 8.2.8.","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":"WordPress Nelio AB Testing plugin \u003c= 8.2.8 - Sensitive Data Exposure vulnerability","id":"CVE-2026-40742","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Tutor LMS plugin \u003c= 3.9.7 - Broken Access Control vulnerability","id":"CVE-2026-40743"},"packages":[],"prev":{"headline":"WordPress Redsys for WooCommerce Light plugin \u003c= 7.0.0 - Broken Access Control vulnerability","id":"CVE-2026-40741"},"products":["Nelio AB Testing"],"published":"2026-04-15","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-29","vendors":["Nelio Software"]},"summary":"Attackers can access sensitive data due to missing authorization checks in the Nelio AB Testing plugin for WordPress.","url":"https://insights.sbomify.com/CVE-2026-40742/"}
