An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53952 in the wild and no public exploit code.\n\nAffected product: GetSimpleCMS. 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-2026-53952/ (Markdown: https://insights.sbomify.com/CVE-2026-53952/index.md)","id":"CVE-2026-53952","markdown":"https://insights.sbomify.com/CVE-2026-53952/index.md","name":"CVE-2026-53952","record":{"aliases":["GHSA-rw2c-w4mg-46g4"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"GetSimple CMS","requires_auth":"none","summary":"Unauthenticated attackers can create admin accounts due to a logic flaw preventing the deletion of the setup script after installation.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-489","name":"Active Debug Code"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS.
