CVE-2026-71571
iCagenda (com_icagenda) 4.0.8 to 4.0.11 - Unauthenticated SQL Injection
iCagenda 4.0.8 through 4.0.11 (the Joomla 4/5/6 branch) contain an unauthenticated SQL injection in mod_icagenda_calendar, reachable through com_ajax with no session, token or account (CVE-2026-67365, CVSS 4.0 9.2 Critical). An anonymous visitor can read arbitrary database contents including Joomla user password hashes. This is a separate flaw from the earlier CVE-2026-48939 file upload RCE and was reported by Joep van Antwerpen of Onvio. Fixed in 4.0.12; update to 4.0.13 or later, which also fixes a stored XSS regression introduced in 4.0.8. The legacy Joomla 3 branch (3.9.x) is not affected by this SQL injection.
