An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-78078 in the wild and no public exploit code.\n\nAffected product: joomshaper.com Helix Ultimate 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-2026-78078/ (Markdown: https://insights.sbomify.com/CVE-2026-78078/index.md)","id":"CVE-2026-78078","markdown":"https://insights.sbomify.com/CVE-2026-78078/index.md","name":"CVE-2026-78078","record":{"aliases":["GHSA-wmp3-68pg-cwp7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Helix Ultimate","requires_auth":"high_privilege","summary":"Attackers can upload malicious files disguised as images in Helix Ultimate, potentially leading to code execution on Joomla sites.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Joomla Extension - joomshaper.com - Privileged File Upload Bypass via Content Spoofing in Helix Ultimate \u003c 2.2.10 - Image uploads previously validated only file extension and basic size parameters.
