Database disclosure via category identifier SQL injection
Published Jun 19, 2026 · Updated Jun 19, 2026
SQL injection in JoomlaThat Calendar Planner 1.0.1 allows remote attackers to read database data through the events view category_id parameter. The events view incorporates the GET-supplied category_id value into a database query without neutralizing SQL syntax, so injected clauses execute as query directives. No account or user interaction is required; a reachable Joomla site with the affected extension can disclose sensitive records from its backing database.
