About the Security Update
On 12 September 2026, Yugorin of the Samar Group (https://retroportal.org) responsibly disclosed a serious security vulnerability in JoomGallery. The vulnerability is tracked as CVE-2026-84048.
This vulnerability has been fixed in JoomGallery version 4.4.2. We recommend that all administrators running an affected installation update to version 4.4.2 or later as soon as possible.

We consider this vulnerability to pose a high risk. It can be exploited on any JoomGallery installation, regardless of how the gallery has been set up or configured.
CVE-2026-84048 – Unauthenticated Upload of Arbitrary Files
The vulnerability allows arbitrary files to be uploaded to the server without authentication via an internal endpoint, by accessing a specific URL. These files are stored on the server as unspecified data together with a .info file. On inadequately secured or configured servers, these files may also be executable, which in the worst case could result in the server being compromised.
Uploaded files are stored in the configured Joomla! temp directory and may look like this:
- aabbccddeeff00112233445566778899
- aabbccddeeff00112233445566778899.info
