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-2026-100237 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation Mediawiki - Thanks 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-2026-100237/ (Markdown: https://insights.sbomify.com/CVE-2026-100237/index.md)","id":"CVE-2026-100237","markdown":"https://insights.sbomify.com/CVE-2026-100237/index.md","name":"CVE-2026-100237","record":{"aliases":["GHSA-vfcj-hxgx-8jpc"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki Thanks Extension","requires_auth":"none","summary":"Stored XSS in the MediaWiki Thanks Extension allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"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 ('cross-site scripting') vulnerability in The Wikimedia Foundation Mediawiki - Thanks Extension allows Stored XSS.\n\nThis issue affects Mediawiki - Thanks Extension: from * before 1.43.10/1.45.5/1.46.1.","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 i18n XSS in the Flow integration of Thanks","id":"CVE-2026-100237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Flow colon-separator and flow-guidedtour-optin-welcome-description messages allow stored XSS","id":"CVE-2026-100238"},"packages":[],"prev":{"headline":"Dpdk: dpdk: heap out-of-bounds read/write in gso header copy","id":"CVE-2026-100236"},"products":["Mediawiki - Thanks 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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-25","vendors":["The Wikimedia Foundation"]},"summary":"Stored XSS in the MediaWiki Thanks Extension allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2026-100237/"}
