Database disclosure and service interruption via HQL injection

Published Jan 10, 2026 · Updated Jan 10, 2026

SQL injection in XWiki Full Calendar Macro before 2.4.5 allows remote attackers with page-view rights to read database data or interrupt service. Calendar.JSONService accepted a request-supplied HQL statement or interpolated request parameters into an HQL query, then executed it with programming rights. Guest access is sufficient when the page is viewable; the vendor does not specify how the denial of service interrupts XWiki.
