Every connected Joomla site is checked against them on each audit. ## Is my site affected? Your site is affected if it runs DPCalendar in any of these ranges: - from 9.0.0 up to but not including 10.12.1 - from 9.0.0 up to but not including 10.11.2 - from 9.0.0 up to and including 10.11.2 - from 7.0.0 up to but not including 8.19.6 - from 5.5.0 up to but not including 8.19.5 - from 8.18.0 up to but not including 8.19.4 - from 8.0.0 up to and including 8.14.0 - **Latest safe version** - 10.12.1 or later. No rule we check matches that release or any newer one. - **What to do** - Update DPCalendar to 10.12.1 or later from the vendor, then confirm the installed version on the Joomla administrator's Extensions: Manage screen.

CVE Affected versions Fixed in Severity Added [CVE-2026-78071](https://mysites.guru/vulnerabilities/CVE-2026-78071/)CVSS 7.5 from 7.0.0 up to but not including 8.19.6 8.19.6 High 2026-08-28 [CVE-2026-78071](https://mysites.guru/vulnerabilities/CVE-2026-78071/)CVSS 7.5 from 9.0.0 up to but not including 10.12.1 10.12.1 High 2026-08-28 [CVE-2026-78070](https://mysites.guru/vulnerabilities/CVE-2026-78070/)CVSS 6.9 from 5.5.0 up to but not including 8.19.5 8.19.5 Medium 2026-08-28 [CVE-2026-78070](https://mysites.guru/vulnerabilities/CVE-2026-78070/)CVSS 6.9 from 9.0.0 up to and including 10.11.2 after 10.11.2 Medium 2026-08-28 [CVE-2026-57831](https://mysites.guru/vulnerabilities/CVE-2026-57831/)CVSS 8.7 from 9.0.0 up to but not including 10.11.2 10.11.2 High 2026-07-13 [CVE-2026-57831](https://mysites.guru/vulnerabilities/CVE-2026-57831/)CVSS 8.7 from 8.18.0 up to but not including 8.19.4 8.19.4 High 2026-07-13 [CVE-2024-21727](https://mysites.guru/vulnerabilities/CVE-2024-21727/)CVSS 6.1 from 8.0.0 up to and including 8.14.0 update to 8.14.1 Medium 2024-02-15 ## What we check for High[CVE-2026-78071](https://mysites.guru/vulnerabilities/CVE-2026-78071/)2026-08-28 ### DPCalendar (com\_dpcalendar) 7.0.0 to 8.19.5 (Joomla 3) - Authenticated Stored Cross-Site Scripting DPCalendar renders a calendar location title into a data-title HTML attribute without escaping it, giving a stored cross-site scripting flaw. A payload such as x" onmouseover="alert(1) has no HTML tags, so it passes through the filterText input filter unchanged and breaks out of the attribute on output, where it becomes a live event handler. Storing the payload requires an account with DPCalendar location create permission (CVSS 4.0 vector PR:H), but the script then runs in the browser of every visitor who views that location page, so the permission bounds who can plant it and not who it hits. This was reported in two stages. Toan Le found the original as vendor issue 12203, fixed on 2026-08-27 in 8.19.5 and 10.12.0, which escaped nine of the ten data-title sinks in the component. mySites.guru proved the same day that the tenth was still open, at components/com\_dpcalendar/site/tmpl/location/default\_map.php line 23, reported it to Digital Peak and the Joomla Security Strike Team, and Digital Peak confirmed it on 2026-08-28. That last sink was closed on 2026-09-10 in 8.19.6 and 10.12.1, along with seven identical sinks in the free mod\_dpcalendar\_upcoming module templates (blog, default, horizontal, icon, panel, simple and timeline). CVE-2026-78071 was updated on 2026-09-10 to widen its affected range to 7.0.0-8.19.5 and 9.0.0-10.12.0 and to credit both finders. On Joomla 3 the fixed version is 8.19.6, which is a security-only release containing this one change. If you have overridden the DPCalendar location templates, the unescaped output is still in your override and updating the extension will not reach it. Affected versions: ≥ 7.0.0 and < 8.19.6 Full advisory: [our disclosure post](https://mysites.guru/blog/digital-peak-claude-security-audit-release/) High[CVE-2026-78071](https://mysites.guru/vulnerabilities/CVE-2026-78071/)2026-08-28 ### DPCalendar (com\_dpcalendar) 9.0.0 to 10.12.0 (Joomla 4 to 6) - Authenticated Stored Cross-Site Scripting DPCalendar renders a calendar location title into a data-title HTML attribute without escaping it, giving a stored cross-site scripting flaw.

The 9.x line has no patch of its own, so sites there need the staged upgrade across to 10.12.1 rather than a point update. If you have overridden the DPCalendar location templates, the unescaped output is still in your override and updating the extension will not reach it.

The filter\_created\_by request parameter is placed into the events query without an integer cast (site EventsModel::getListQuery), so an anonymous visitor can inject boolean conditions and read arbitrary database contents including user password hashes and the Joomla secret through the public events feed at index.php?option=com\_dpcalendar&view=events&format=raw. No login, token or CSRF is required. It is a read-only injection (no write or RCE). All editions (Free, Pro, Business) share the vulnerable site model. The flaw dates to 8.18.0 and affects every current-line release up to and including 10.11.0. Fixed in 10.11.2, which integer-casts the author filter. Update to 10.11.2 or later; on the 9.x line the upgrade path is 9.x to 10.0.0, then 10.6.0, then 10.11.2. Joomla 3 (8.x) sites are handled by a separate rule (fixed in 8.19.4). Temporary mitigation: block non-numeric filter\_created\_by at the WAF, or unpublish DPCalendar front-end menu items. Discovered and reported by mySites.guru.

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.

A site is affected if its installed version is in any of these ranges: from 9.0.0 up to but not including 10.12.1; from 9.0.0 up to but not including 10.11.2; from 9.0.0 up to and including 10.11.2; from 7.0.0 up to but not including 8.19.6; from 5.5.0 up to but not including 8.19.5; from 8.18.0 up to but not including 8.19.4; from 8.0.0 up to and including 8.14.0. What is the latest safe version of DPCalendar? 10.12.1. Every vulnerability tracked here is fixed by 10.12.1, and no rule we check matches that release or any later one. How do I check which version of DPCalendar my Joomla site runs? The installed version is listed on the Joomla administrator's Extensions: Manage screen; search it for com\_dpcalendar. mySites.guru reads the installed version on every audit of a connected site and checks it against these rules. ## Running DPCalendar on a site you manage? A free audit tells you which of your Joomla and WordPress sites run an affected version, which are out of date, and which have not been backed up. No card required. If a site is already compromised, [fix.mysites.guru](https://fix.mysites.guru/) is a single fixed fee per incident, usually resolved the same day. This check is part of the [mySites.guru Joomla vulnerability scanner](https://mysites.guru/joomla-vulnerability-scanner/), which reads every installed extension's version on each audit.
