Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-126562 in the wild and no public exploit code.\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-2026-126562/ (Markdown: https://insights.sbomify.com/CVE-2026-126562/index.md)","id":"CVE-2026-126562","markdown":"https://insights.sbomify.com/CVE-2026-126562/index.md","name":"CVE-2026-126562","record":{"aliases":["GHSA-cm2r-7rp4-3767","GHSA-jwx8-mm92-gv95"],"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":"Users with page-edit rights can create mutually referencing concept pages that exhaust memory or stack in Semantic MediaWiki.","user_interaction":"not_required","vuln_class":"denial_of_service","vulnerable_functions":["ConceptDescriptionInterpreter"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"Semantic MediaWiki 3.0.0 before 7.4.1 contains an uncontrolled recursion vulnerability in the ElasticStore ConceptDescriptionInterpreter that only detects directly self-referencing concepts.
