CVE-2026-5957
CVSS v3.1
6.5
Medium
| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
EmailKit versions prior to 1.6.6
Description
The EmailKit plugin for WordPress contains a flaw in the
create template() function of the CheckForm class. The issue arises from improper path traversal validation when realpath() is called on a base directory that may not exist, returning false. In PHP 8.x, this leads to a type conversion where strpos() treats the false value as an empty string, allowing the validation check to be bypassed. Authenticated attackers with Author-level access or higher can exploit this to read arbitrary files from the server, such as wp-config.php, by providing an absolute path to the 'emailkit-editor-template' REST API parameter.Recommendations
Update the plugin to a version later than 1.6.5.
As a temporary workaround, restrict access to the 'emailkit-editor-template' REST API parameter for users with Author-level permissions.
Fix
Path traversal
