An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-0670 in the wild and no public exploit code.\n\nAffected product: Wikimedia Foundation MediaWiki - ProofreadPage 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-2026-0670/ (Markdown: https://insights.sbomify.com/CVE-2026-0670/index.md)","id":"CVE-2026-0670","markdown":"https://insights.sbomify.com/CVE-2026-0670/index.md","name":"CVE-2026-0670","record":{"aliases":["GHSA-m5v6-566h-wgcg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki ProofreadPage extension","requires_auth":"none","summary":"Stored XSS in MediaWiki ProofreadPage allows attackers to inject scripts via system messages, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"proofread_page","vendor":"wikisource"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","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 Wikimedia Foundation MediaWiki - ProofreadPage Extension allows Cross-Site Scripting (XSS).This issue affects MediaWiki - ProofreadPage Extension: 1.45, 1.44, 1.43, 1.39.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Stored XSS through a system message and a user-provided parameter in ProofreadPage","id":"CVE-2026-0670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Multiple stored i18n/message-key XSSes in UploadWizard","id":"CVE-2026-0671"},"packages":[],"prev":{"headline":"Path Traversal vulnerability in CSS extension on certain web servers","id":"CVE-2026-0669"},"products":["MediaWiki - ProofreadPage Extension"],"published":"2026-01-07","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-07","vendors":["Wikimedia Foundation"]},"summary":"Stored XSS in MediaWiki ProofreadPage allows attackers to inject scripts via system messages, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2026-0670/"}
