An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100382 in the wild and no public exploit code.\n\nAffected product: Wikimedia Foundation Mediawiki - ExternalData 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-2026-100382/ (Markdown: https://insights.sbomify.com/CVE-2026-100382/index.md)","id":"CVE-2026-100382","markdown":"https://insights.sbomify.com/CVE-2026-100382/index.md","name":"CVE-2026-100382","record":{"aliases":["GHSA-vwh3-jq98-4w28"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki ExternalData extension","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary OS commands via wikitext in the MediaWiki ExternalData extension.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in Wikimedia Foundation Mediawiki - ExternalData Extension allows OS Command Injection.\n\nThis issue affects Mediawiki - ExternalData Extension: from * before 3.7.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-27","github_poc":1,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-27T15:31:44Z","kind":"github_poc","ref":"https://github.com/nth347/mediawiki-CVE-2026-100382","stars":3,"title":null}],"tier":"poc_unverified"},"has_fix":null,"headline":"Unauthenticated remote code execution through wikitext in ExternalData","id":"CVE-2026-100382","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Stored i18n XSS in WikiLambda's VisualEditor integration","id":"CVE-2026-100383"},"packages":[],"prev":{"headline":"UploadWizard Flickr collection and set titles allow DOM XSS","id":"CVE-2026-100381"},"products":["Mediawiki - ExternalData Extension"],"published":"2026-09-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-26","vendors":["Wikimedia Foundation"]},"summary":"Unauthenticated attackers can execute arbitrary OS commands via wikitext in the MediaWiki ExternalData extension.","url":"https://insights.sbomify.com/CVE-2026-100382/"}
