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-2024-47845 exists.\n\nAffected product: The Wikimedia Foundation Mediawiki - CSS Extension. 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-2024-47845/ (Markdown: https://insights.sbomify.com/CVE-2024-47845/index.md)","id":"CVE-2024-47845","markdown":"https://insights.sbomify.com/CVE-2024-47845/index.md","name":"CVE-2024-47845","record":{"aliases":["GHSA-rxh5-jm9f-fmwj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki CSS Extension","requires_auth":"none","summary":"Attackers can bypass CSS sanitization to inject malicious code, potentially leading to script execution or security bypasses in MediaWiki installations.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"wikimedia-extensions-css","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:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"Improper Encoding or Escaping of Output vulnerability in The Wikimedia Foundation Mediawiki - CSS Extension allows Code Injection.This issue affects Mediawiki - CSS Extension: 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":"CSS sanitizer used incorrectly, and is easily bypassed","id":"CVE-2024-47845","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"Special:DeleteCargoTable and Special:SwitchCargoTable have no CSRF protection","id":"CVE-2024-47846"},"packages":[],"prev":{"headline":"Path traversal when loading stylesheets","id":"CVE-2024-47841"},"products":["Mediawiki - CSS Extension"],"published":"2024-10-05","related":[{"cvss_score":6.9,"headline":"Path traversal when loading stylesheets","id":"CVE-2024-47841","kev_date_added":null,"published":"2024-10-05"}],"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 bypass CSS sanitization to inject malicious code, potentially leading to script execution or security bypasses in MediaWiki installations.","url":"https://insights.sbomify.com/CVE-2024-47845/"}
