An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-47840 exists.\n\nAffected product: The Wikimedia Foundation Mediawiki - Apex skin. 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-2024-47840/ (Markdown: https://insights.sbomify.com/CVE-2024-47840/index.md)","id":"CVE-2024-47840","markdown":"https://insights.sbomify.com/CVE-2024-47840/index.md","name":"CVE-2024-47840","record":{"aliases":["GHSA-mmf2-8r78-pm42"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki Apex skin","requires_auth":"none","summary":"Attackers can inject malicious scripts via the sidebar in the MediaWiki Apex skin, potentially compromising user sessions and data.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"apex","vendor":"wikimedia"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"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 The Wikimedia Foundation Mediawiki - Apex skin allows Stored XSS.This issue affects Mediawiki - Apex skin: from 1.39.X before 1.39.9, from 1.41.X before 1.41.3, from 1.42.X before 1.42.2.","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":"Stored XSS through sidebar in Apex skin","id":"CVE-2024-47840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"Path traversal when loading stylesheets","id":"CVE-2024-47841"},"packages":[],"prev":{"headline":"Admidio vulnerable to HTML Injection In The Messages Section","id":"CVE-2024-47836"},"products":["Mediawiki - Apex skin"],"published":"2024-10-05","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-07","vendors":["The Wikimedia Foundation"]},"summary":"Attackers can inject malicious scripts via the sidebar in the MediaWiki Apex skin, potentially compromising user sessions and data.","url":"https://insights.sbomify.com/CVE-2024-47840/"}
