Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-26477 exists.\n\nAffected product: DokuWiki. 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-2026-26477/ (Markdown: https://insights.sbomify.com/CVE-2026-26477/index.md)","id":"CVE-2026-26477","markdown":"https://insights.sbomify.com/CVE-2026-26477/index.md","name":"CVE-2026-26477","record":{"aliases":["DEBIAN-CVE-2026-26477","GHSA-gwpq-c4hc-7qhj","UBUNTU-CVE-2026-26477"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DokuWiki","requires_auth":"low_privilege","summary":"A remote attacker can cause a denial of service in DokuWiki via the media upload function, requiring administrators to upgrade the software.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dokuwiki","vendor":"dokuwiki"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"An issue in Dokuwiki v.2025-05-14b \"Librarian\" [56.2] allows a remote attacker to cause a denial of service via the media_upload_xhr() function in the media.php file","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in DokuWiki","id":"CVE-2026-26477","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in n/a","id":"CVE-2026-26478"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2026-26464"},"products":["DokuWiki"],"published":"2026-04-03","related":[{"cvss_score":9.6,"headline":"Code injection in n/a","id":"CVE-2018-15474","kev_date_added":null,"published":"2018-09-07"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2009-1960","kev_date_added":null,"published":"2009-06-06"},{"cvss_score":8.6,"headline":"Server-side request forgery in n/a","id":"CVE-2016-7964","kev_date_added":null,"published":"2016-10-31"},{"cvss_score":7.5,"headline":"Missing authorization in n/a","id":"CVE-2010-0288","kev_date_added":null,"published":"2010-02-15"},{"cvss_score":6.9,"headline":"Dokuwiki 2018-04-22b - Username Enumeration","id":"CVE-2019-25338","kev_date_added":null,"published":"2026-02-12"},{"cvss_score":6.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2010-0289","kev_date_added":null,"published":"2010-02-15"},{"cvss_score":6.5,"headline":"Open redirect in n/a","id":"CVE-2016-7965","kev_date_added":null,"published":"2016-10-31"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["DokuWiki"]},"summary":"A remote attacker can cause a denial of service in DokuWiki via the media upload function, requiring administrators to upgrade the software.","url":"https://insights.sbomify.com/CVE-2026-26477/"}
