Vulnerability Title
Joomla Extension - getk2.org - Exposure of sensitive files via attachment copy in K2 extension for Joomla < 2.26
Source: NVD (National Vulnerability Database)
Vulnerability Description
The K2 frontend article-save handler accepts an `attachment[N][existing]` POST field that is concatenated with `JPATH_SITE/` and passed to `JFile::copy()`. `JPath::clean` does NOT strip `..`, and there is no allow-list of source paths. An Author can therefore copy `configuration.php` (or any other file readable by the web user — including `../../../etc/passwd`) into `/media/k2/attachments/`, then retrieve the contents via the K2 attachment-download endpoint.
