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-2026-100241 in the wild and no public exploit code.\n\nAffected product: Wikimedia Foundation Mediawiki - EventBus 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-2026-100241/ (Markdown: https://insights.sbomify.com/CVE-2026-100241/index.md)","id":"CVE-2026-100241","markdown":"https://insights.sbomify.com/CVE-2026-100241/index.md","name":"CVE-2026-100241","record":{"aliases":["GHSA-hm8p-x35f-6gwh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki EventBus Extension","requires_auth":"none","summary":"An attacker can view private change tags intended for authorized users only, exposing sensitive metadata to anonymous visitors.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Wikimedia Foundation Mediawiki - EventBus Extension allows Excavation.\n\nThis issue affects Mediawiki - EventBus Extension: 1.47.0-alpha.","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":"Private change tags exposed to anonymous users via revision-tags-change events","id":"CVE-2026-100241","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"DataTransfer depends on phpspreadsheet version vulnerable to CVE-2026-59933 (XLS/OLE memory exhaustion)","id":"CVE-2026-100242"},"packages":[],"prev":{"headline":"TemplateSandbox does not check read permissions for the page being previewed","id":"CVE-2026-100240"},"products":["Mediawiki - EventBus Extension"],"published":"2026-09-29","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["Wikimedia Foundation"]},"summary":"An attacker can view private change tags intended for authorized users only, exposing sensitive metadata to anonymous visitors.","url":"https://insights.sbomify.com/CVE-2026-100241/"}
