CVE-2026-78070MediumPublished 28 August 2026
DPCalendar (com_dpcalendar) 5.5.0 to 8.19.4 (Joomla 3) - Authenticated Blind SQL Injection
DPCalendar contains a blind SQL injection reachable by saving a Joomla article. The DPCalendar content plugin passes the order and orderdir parameters of a {dpcalendar} tag into the events query ORDER BY clause without validating them against the model filter_fields allow-list. The sink used the database escape() helper, which secures string literals but not SQL identifiers, so the sort column is injectable. Exploitation requires an account holding permission to create or update articles, so this is authenticated and privileged (CVSS 4.0 vector PR:H), not anonymous. Reported by Toan Le as vendor issue 12206. Fixed in 10.12.0 on the Joomla 4 to 6 branch and backported to 8.19.5 on the Joomla 3 branch. Temporary mitigation: disable the "Content - DPCalendar" plugin, which is the only route in.
