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-2026-66494 in the wild and no public exploit code.\n\nAffected product: joomshaper.com SP Page Builder 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-2026-66494/ (Markdown: https://insights.sbomify.com/CVE-2026-66494/index.md)","id":"CVE-2026-66494","markdown":"https://insights.sbomify.com/CVE-2026-66494/index.md","name":"CVE-2026-66494","record":{"aliases":["GHSA-vcvg-2gmm-mmpg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla SP Page Builder","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious JavaScript into the SP Page Builder editor, which executes when an administrator views the page.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Joomla Extension - joomshaper.com - Unauthenticated stored XSS in Shapes API endpoint SP Page Builder \u003c 6.7.0 - An unauthenticated attacker can store malicious JavaScript in a Joomla site's database via a single HTTP request.
