An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-63301 in the wild and no public exploit code.\n\nAffected product: OpenSolution Quick.CMS. 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-2026-63301/ (Markdown: https://insights.sbomify.com/CVE-2026-63301/index.md)","id":"CVE-2026-63301","markdown":"https://insights.sbomify.com/CVE-2026-63301/index.md","name":"CVE-2026-63301","record":{"aliases":["GHSA-4pmv-mf66-4v3h"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Quick.CMS","requires_auth":"high_privilege","summary":"An attacker can cause a Denial of Service in Quick.CMS by deleting the primary language via an unprotected API endpoint, potentially exploiting a CSRF flaw.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-602","name":"Client-Side Enforcement of Server-Side Security"}],"description":"In Quick.CMS, the administrative user interface restricts deletion of the primary language by omitting the corresponding option from the interface; however, the underlying language-deletion API endpoint does not enforce an equivalent server-side authorization check.
