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-2026-74803 in the wild and no public exploit code.\n\nAffected product: yootheme.com Zoo 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-2026-74803/ (Markdown: https://insights.sbomify.com/CVE-2026-74803/index.md)","id":"CVE-2026-74803","markdown":"https://insights.sbomify.com/CVE-2026-74803/index.md","name":"CVE-2026-74803","record":{"aliases":["GHSA-c2jh-c375-pjcv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Zoo extension","requires_auth":"none","summary":"Unauthenticated attackers can upload arbitrary files via the image element, potentially leading to remote code execution on Joomla sites using the Zoo extension.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/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 - yootheme.com - Unauthenticated arbitrary file upload in Zoo \u003c 4.1.64 - The image element accepts arbitrary files when the client-supplied Content-Type falls within the image MIME group.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Joomla Extension - yootheme.com - Unauthenticated arbitrary file upload in Zoo \u003c 4.1.64","id":"CVE-2026-74803","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Joomla Extension - yootheme.com - Unauthenticated SQL injection in Zoo \u003c 4.1.64","id":"CVE-2026-74804"},"packages":[],"prev":{"headline":"SiYuan 3.7.3 Cross-Site WebSocket Hijacking via network proxy","id":"CVE-2026-74802"},"products":["Zoo extension for Joomla"],"published":"2026-08-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-21","vendors":["yootheme.com"]},"summary":"Unauthenticated attackers can upload arbitrary files via the image element, potentially leading to remote code execution on Joomla sites using the Zoo extension.","url":"https://insights.sbomify.com/CVE-2026-74803/"}
