An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-0420 exists.\n\nAffected product: Unknown Custom Post Type and Taxonomy GUI Manager. 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-2023-0420/ (Markdown: https://insights.sbomify.com/CVE-2023-0420/index.md)","id":"CVE-2023-0420","markdown":"https://insights.sbomify.com/CVE-2023-0420/index.md","name":"CVE-2023-0420","record":{"aliases":["GHSA-qrm5-6xmw-6xcq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Attackers can inject stored XSS payloads via CSRF, allowing execution of malicious scripts in admin sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"custom_post_type_and_taxonomy_gui_manager","vendor":"custom_post_type_and_taxonomy_gui_manager_project"}],"cvss":{"score":4.8,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The Custom Post Type and Taxonomy GUI Manager WordPress plugin through 1.1 does not have CSRF, and is lacking sanitising as well as escaping in some parameters, allowing attackers to make a logged in admin put Stored Cross-Site Scripting payloads via CSRF","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Custom Post Type and Taxonomy GUI Manager \u003c= 1.1 - Stored XSS via CSRF","id":"CVE-2023-0420","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Cloud Manager \u003c= 1.0 - Reflected XSS","id":"CVE-2023-0421"},"packages":[],"prev":{"headline":"Shortcode for Font Awesome \u003c 1.4.1 - Contributor+ Stored XSS","id":"CVE-2023-0419"},"products":["Custom Post Type and Taxonomy GUI Manager"],"published":"2023-04-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-04","vendors":["Unknown"]},"summary":"Attackers can inject stored XSS payloads via CSRF, allowing execution of malicious scripts in admin sessions.","url":"https://insights.sbomify.com/CVE-2023-0420/"}
