An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-77028 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-2026-77028/ (Markdown: https://insights.sbomify.com/CVE-2026-77028/index.md)","id":"CVE-2026-77028","markdown":"https://insights.sbomify.com/CVE-2026-77028/index.md","name":"CVE-2026-77028","record":{"aliases":["GHSA-84gv-j7pq-p96w"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Zoo extension","requires_auth":"none","summary":"Attackers can execute arbitrary scripts or redirect users via the submission redirect parameter in the Zoo extension for Joomla.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Joomla Extension - yootheme.com - Reflected XSS and open redirect via the submission redirect parameter in Zoo \u003c 4.1.66","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 - Reflected XSS and open redirect via the submission redirect parameter in Zoo \u003c 4.1.66","id":"CVE-2026-77028","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Joomla Extension - yootheme.com - Missing CSRF tokens on front-end state changes in Zoo \u003c 4.1.66","id":"CVE-2026-77029"},"packages":[],"prev":{"headline":"Joomla Extension - fabrikar.com - Unauthenticated stored XSS in Fabrik \u003c 4.7.2","id":"CVE-2026-77027"},"products":["Zoo extension for Joomla"],"published":"2026-08-21","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-21","vendors":["yootheme.com"]},"summary":"Attackers can execute arbitrary scripts or redirect users via the submission redirect parameter in the Zoo extension for Joomla.","url":"https://insights.sbomify.com/CVE-2026-77028/"}
