An attacker can exploit it over the internet without logging in, 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-2023-4687 exists.\n\nAffected product: Unknown Page Builder: Pagelayer. 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-2023-4687/ (Markdown: https://insights.sbomify.com/CVE-2023-4687/index.md)","id":"CVE-2023-4687","markdown":"https://insights.sbomify.com/CVE-2023-4687/index.md","name":"CVE-2023-4687","record":{"aliases":["GHSA-mqx8-vg45-6p4q"],"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":"none","summary":"Unauthenticated attackers can inject malicious scripts into scheduled post headers or footers, potentially leading to code execution or account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"pagelayer","vendor":"pagelayer"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The Page Builder: Pagelayer WordPress plugin before 1.7.7 doesn't prevent unauthenticated attackers from updating a post's header or footer code on scheduled posts.","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":"PageLayer \u003c 1.7.7 - Unauthenticated Stored XSS","id":"CVE-2023-4687","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Acronis Agent","id":"CVE-2023-4688"},"packages":[],"prev":{"headline":"WP Customer Reviews \u003c= 3.6.6 - Authenticated (Subscriber+) Sensitive Information Exposure","id":"CVE-2023-4686"},"products":["Page Builder: Pagelayer"],"published":"2023-10-16","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-35944","kev_date_added":null,"published":"2021-01-01"},{"cvss_score":7.4,"headline":"Missing authorization in n/a","id":"CVE-2020-35947","kev_date_added":null,"published":"2021-01-01"},{"cvss_score":6.5,"headline":"WordPress PageLayer plugin \u003c= 1.8.1 - Broken Access Control vulnerability","id":"CVE-2024-30465","kev_date_added":null,"published":"2024-06-09"},{"cvss_score":6.4,"headline":"Cross-site scripting in Page Builder: Pagelayer – Drag and Drop website builder","id":"CVE-2024-2504","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":6.4,"headline":"Cross-site scripting in Page Builder: Pagelayer – Drag and Drop website builder","id":"CVE-2024-2127","kev_date_added":null,"published":"2024-03-07"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2020-36383","kev_date_added":null,"published":"2021-06-07"}],"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":"2025-04-23","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious scripts into scheduled post headers or footers, potentially leading to code execution or account takeover.","url":"https://insights.sbomify.com/CVE-2023-4687/"}
