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-2026-77993 in the wild and no public exploit code.\n\nAffected product: joomlack.fr Page Builder CK 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-2026-77993/ (Markdown: https://insights.sbomify.com/CVE-2026-77993/index.md)","id":"CVE-2026-77993","markdown":"https://insights.sbomify.com/CVE-2026-77993/index.md","name":"CVE-2026-77993","record":{"aliases":["GHSA-vrrp-8526-8v58"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla Page Builder CK","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in victim browsers via the iscontenttype parameter in the Page Builder CK 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"}],"description":"Joomla Extension - joomlack.fr - Reflected XSS in Page Builder CK \u003c 3.6.5 - The Joomla extension Page Builder CK is vulnerable to a reflected XSS via the iscontenttype parameter.","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 - joomlack.fr - Reflected XSS in Page Builder CK \u003c 3.6.5","id":"CVE-2026-77993","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 - joomlack.fr - Second order SQL injection in Page Builder CK \u003c 3.6.5","id":"CVE-2026-77994"},"packages":[],"prev":{"headline":"Joomla Extension - fabrikar.com - heredoc terminator breakout in the calc element in Fabrik \u003c 4.7.2","id":"CVE-2026-77992"},"products":["Page Builder CK extension for Joomla"],"published":"2026-08-24","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":"partial"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["joomlack.fr"]},"summary":"Attackers can execute arbitrary scripts in victim browsers via the iscontenttype parameter in the Page Builder CK extension for Joomla.","url":"https://insights.sbomify.com/CVE-2026-77993/"}
