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-2026-84048 in the wild and no public exploit code.\n\nAffected product: joomgalleryfriends.net JoomGallery 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-2026-84048/ (Markdown: https://insights.sbomify.com/CVE-2026-84048/index.md)","id":"CVE-2026-84048","markdown":"https://insights.sbomify.com/CVE-2026-84048/index.md","name":"CVE-2026-84048","record":{"aliases":["GHSA-x2gj-69fv-g59f"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Joomla JoomGallery extension","requires_auth":"none","summary":"Unauthenticated attackers can upload arbitrary files via the TUS endpoint, potentially leading to code execution on non-standard server configurations.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:A","version":"4.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Joomla Extension - joomgalleryfriends.net - Unauthenticated arbitrary file upload via the TUS endpoint in JoomGallery \u003c 4.4.2 - The TUS endpoint allows arbitrary file uploads, however neither file name nor file extension are under attacker control.
