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-2026-22711 exists.\n\nAffected product: The Wikimedia Foundation Mediawiki - Wikilove 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-2026-22711/ (Markdown: https://insights.sbomify.com/CVE-2026-22711/index.md)","id":"CVE-2026-22711","markdown":"https://insights.sbomify.com/CVE-2026-22711/index.md","name":"CVE-2026-22711","record":{"aliases":["GHSA-cp48-9xx4-pmj6"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki WikiLove extension","requires_auth":"none","summary":"Stored XSS in MediaWiki WikiLove extension allows attackers to inject scripts via system messages, potentially compromising user sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"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:L/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-87","name":"Improper Neutralization of Alternate XSS Syntax"}],"description":"Improper neutralization of alternate XSS syntax vulnerability in The Wikimedia Foundation Mediawiki - Wikilove Extension allows Cross-Site Scripting (XSS).The issue has been remediated on the `master` branch, and in the release branches for MediaWiki versions 1.43, 1.44, and 1.45.","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 system messages in WikiLove","id":"CVE-2026-22711","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"ApprovedRevs allows bypassing the inline CSS sanitizer","id":"CVE-2026-22712"},"packages":[],"prev":{"headline":"Stored XSS through autocomment system messages in Wikibase","id":"CVE-2026-22710"},"products":["Mediawiki - Wikilove Extension"],"published":"2026-04-07","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)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["The Wikimedia Foundation"]},"summary":"Stored XSS in MediaWiki WikiLove extension allows attackers to inject scripts via system messages, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2026-22711/"}
