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-2024-43963 exists.\n\nAffected product: WaspThemes YellowPencil Visual CSS Style Editor. 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-2024-43963/ (Markdown: https://insights.sbomify.com/CVE-2024-43963/index.md)","id":"CVE-2024-43963","markdown":"https://insights.sbomify.com/CVE-2024-43963/index.md","name":"CVE-2024-43963","record":{"aliases":["GHSA-6mc3-f5wc-vw2x"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Reflected XSS in YellowPencil Visual CSS Style Editor allows attackers to inject malicious scripts into web pages viewed by other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"yellowpencil","vendor":"waspthemes"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in WaspThemes YellowPencil Visual CSS Style Editor allows Reflected XSS.This issue affects YellowPencil Visual CSS Style Editor: from n/a through 7.6.1.","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":"WordPress Visual CSS Style Editor plugin \u003c= 7.6.1 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-43963","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress DSGVO All in one for WP plugin \u003c= 4.5 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-43964"},"packages":[],"prev":{"headline":"WordPress LWS Affiliation plugin \u003c= 2.3.4 - Broken Access Control vulnerability","id":"CVE-2024-43962"},"products":["YellowPencil Visual CSS Style Editor"],"published":"2024-08-29","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["WaspThemes"]},"summary":"Reflected XSS in YellowPencil Visual CSS Style Editor allows attackers to inject malicious scripts into web pages viewed by other users.","url":"https://insights.sbomify.com/CVE-2024-43963/"}
