Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-103437 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation MediaWiki ReadingLists 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-2026-103437/ (Markdown: https://insights.sbomify.com/CVE-2026-103437/index.md)","id":"CVE-2026-103437","markdown":"https://insights.sbomify.com/CVE-2026-103437/index.md","name":"CVE-2026-103437","record":{"aliases":["GHSA-c4w7-7m72-q5m9"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki ReadingLists extension","requires_auth":"low_privilege","summary":"Reflected XSS in MediaWiki ReadingLists extension allows attackers to execute arbitrary JavaScript via imported metadata.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":1.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/E:P/S:N/AU:Y/R:U/V:D/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"Improper neutralization of Script-Related HTML tags in a web page (basic XSS) vulnerability in The Wikimedia Foundation MediaWiki ReadingLists extension allows Reflected XSS.\n\nThis issue affects MediaWiki ReadingLists extension: 1.46 and 1.45.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-30","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-30T18:33:57Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-103437","stars":0,"title":"Sanitized report summary and local PoC for CVE-2026-103437"}],"tier":"poc_unverified"},"has_fix":null,"headline":"ReadingLists imported metadata permits JavaScript URL XSS","id":"CVE-2026-103437","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Various rawParams() and escaped() updates to prevent XSS in Wikistories extension","id":"CVE-2026-103438"},"packages":[],"prev":{"headline":"Information disclosure in apcupsd","id":"CVE-2026-103436"},"products":["MediaWiki ReadingLists extension"],"published":"2026-09-30","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["The Wikimedia Foundation"]},"summary":"Reflected XSS in MediaWiki ReadingLists extension allows attackers to execute arbitrary JavaScript via imported metadata.","url":"https://insights.sbomify.com/CVE-2026-103437/"}
