The value was stored exactly as submitted instead of being taken from the connection by the server. It was then printed without output escaping in the administrator backend’s “Helpful articles” overview (views/items/tmpl/default.php). $db->quote() was applied on insert, which protects the SQL statement but does nothing for HTML output. There was no CSRF token, no rate limit, and the vote de-duplication keyed on the same attacker-controlled field.","state":0,"publishedAt":"2026-10-27T11:06:50.198+00:00","modifiedAt":"2026-10-27T11:06:50.198+00:00","affected":[{"ecosystem":"Vendor product","name":"com_djhelpfularticles","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageName\": \"com_djhelpfularticles\",\n                    \"product\": \"DJ-HelpfulArticles extension for Joomla\",\n                    \"vendor\": \"dj-extensions.com\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0.0-1.2.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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","score":8.7,"severity":"HIGH"}],"references":["https://www.dj-extensions.com/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102800","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102800","identifiers":["CVE-2026-102800"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
