An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-65885 in the wild and no public exploit code.\n\nAffected product: balbooa.com Gridbox extension for Joomla. 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-2026-65885/ (Markdown: https://insights.sbomify.com/CVE-2026-65885/index.md)","id":"CVE-2026-65885","markdown":"https://insights.sbomify.com/CVE-2026-65885/index.md","name":"CVE-2026-65885","record":{"aliases":["GHSA-ch97-6m5m-2jh8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Gridbox extension","requires_auth":"high_privilege","summary":"Authenticated attackers can upload arbitrary files in the Gridbox Joomla extension, potentially leading to remote code execution when combined with another vulnerability.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"gridbox","vendor":"balbooa"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:A/AU:Y/U:Red","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Joomla Extension - balbooa.com - Authenticated arbitrary file upload in Gridbox \u003c 2.20.2 - File upload methods allows authenticated attackers to upload arbitrary files.
