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-2026-105421 in the wild and no public exploit code.\n\nAffected product: Kit (formerly ConvertKit) for WooCommerce. 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-2026-105421/ (Markdown: https://insights.sbomify.com/CVE-2026-105421/index.md)","id":"CVE-2026-105421","markdown":"https://insights.sbomify.com/CVE-2026-105421/index.md","name":"CVE-2026-105421","record":{"aliases":["GHSA-mh22-xwgg-mf44"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can bypass access controls in the Kit for WooCommerce plugin to perform unauthorized actions.","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:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Missing Authorization vulnerability in Kit Kit (formerly ConvertKit) for WooCommerce convertkit-for-woocommerce allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Kit (formerly ConvertKit) for WooCommerce: from n/a through 2.2.0.","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 Kit (formerly ConvertKit) for WooCommerce plugin \u003c= 2.2.0 - Broken Access Control vulnerability","id":"CVE-2026-105421","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":"NetBird client SSH config Match line injection via peer FQDN or hostname allows local command execution","id":"CVE-2026-105429"},"packages":[],"prev":{"headline":"Path Traversal in Wing WFTP Server leading to Remote Code Execution","id":"CVE-2026-105420"},"products":["Kit (formerly ConvertKit) for WooCommerce"],"published":"2026-10-05","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":"2026-10-05","vendors":["Kit"]},"summary":"Attackers can bypass access controls in the Kit for WooCommerce plugin to perform unauthorized actions.","url":"https://insights.sbomify.com/CVE-2026-105421/"}
