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-2026-34088 in the wild and no public exploit code.\n\nAffected product: Mediawiki Mediawiki. 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-2026-34088/ (Markdown: https://insights.sbomify.com/CVE-2026-34088/index.md)","id":"CVE-2026-34088","markdown":"https://insights.sbomify.com/CVE-2026-34088/index.md","name":"CVE-2026-34088","record":{"aliases":["DEBIAN-CVE-2026-34088","GHSA-wpmg-m9mx-w7pj","UBUNTU-CVE-2026-34088"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki","requires_auth":"none","summary":"Attackers can view suppressed content via RecentChanges log pages, exposing sensitive information to unauthorized users.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"mediawiki","vendor":"mediawiki"}],"cvss":{"score":1.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/R:U/RE:M","version":"4.0"},"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.\n\nThis issue affects MediaWiki: from * before 1.43.7, 1.44.4, 1.45.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"RecentChanges entries expose suppressed content via generated log page html","id":"CVE-2026-34088","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mediawiki:mediawiki","products":["mediawiki:mediawiki"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Memory leak in Scribunto causes runJobs.php to run out of memory","id":"CVE-2026-34089"},"packages":[],"prev":{"headline":"Users API leaks whether privileged users have their user groups disabled for lack of 2FA","id":"CVE-2026-34087"},"products":["MediaWiki"],"published":"2026-05-11","related":[{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2023-37303","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-29904","kev_date_added":null,"published":"2022-04-29"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-29906","kev_date_added":null,"published":"2022-04-29"},{"cvss_score":9.8,"headline":"Business logic in n/a","id":"CVE-2022-28205","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-28206","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-28209","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Business logic in n/a","id":"CVE-2021-36126","kev_date_added":null,"published":"2021-07-02"}],"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":"2026-05-11","vendors":["Wikimedia Foundation"]},"summary":"Attackers can view suppressed content via RecentChanges log pages, exposing sensitive information to unauthorized users.","url":"https://insights.sbomify.com/CVE-2026-34088/"}
