CVE-2026-48997
CWE-78Published: June 17, 2026· Updated: Jun 23, 2026
Official Description
e107 is a content management system (CMS). Versions 2.3.5 and earlier contain a command injection vulnerability in the ImageMagick resize destination path. In resize_image(), the source path is escaped with escapeshellarg(), but the destination path is inserted inside raw double quotes in the convert command; in the submit-news upload flow, that destination filename includes the first six characters of user-controlled news title input. Because the title filter removes literal spaces but not tab characters, and shell expansions such as $(...) and backticks can survive into the quoted destination argument, /bin/sh -c may evaluate attacker-controlled input. Exploitation is possible only when all of the following non-default settings are enabled: resize_method=ImageMagick, subnews_attach=1, upload_enabled=1, subnews_resize is numeric between 30 and 5000, and the attacker is a non-admin in classes permitted by both subnews_class and upload_class. This issue has been fixed in version 2.3.6.
Technical Analysis
CVE-2026-48997 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.1.
