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-2026-126561 exists.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: SemanticMediaWiki. 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-2026-126561/ (Markdown: https://insights.sbomify.com/CVE-2026-126561/index.md)","id":"CVE-2026-126561","markdown":"https://insights.sbomify.com/CVE-2026-126561/index.md","name":"CVE-2026-126561","record":{"aliases":["GHSA-9w3p-9m8x-j2mw","GHSA-vw39-q2rg-9qg8"],"analysis":{"component_type":"cms_plugin","exploitable_when_present":false,"fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki extension","requires_auth":"low_privilege","requires_specific_call":false,"summary":"Editors lacking edit rights can lock pages with an annotation, blocking other editors and admins indefinitely; Semantic MediaWiki operators should care.","user_interaction":"not_required","vuln_class":"missing_authorization","vulnerable_functions":["TitleQuickPermissions"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Semantic MediaWiki 2.5.0 before 7.4.1 contains a missing authorization vulnerability that allows editors without the edit-protection right to lock pages by adding an Is edit protected annotation.
