CVE-2026-11426: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in WebFactory Under Construction Page (Pro)
The UnderConstructionPage PRO plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 5.76. This is due to the plugin accepting arbitrary local file paths in the template_thumbnail parameter and copying their contents into a publicly accessible uploads file. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary files on the server, which can contain sensitive information.
AI Analysis
Technical Summary
CVE-2026-11426 is a path traversal vulnerability (CWE-22) in the UnderConstructionPage PRO plugin for WordPress, affecting all versions up to and including 5.76. The plugin accepts arbitrary local file paths via the template_thumbnail parameter and copies their contents into a publicly accessible uploads directory. Authenticated attackers with Subscriber-level privileges or higher can exploit this to read arbitrary files on the server, potentially exposing sensitive data. The vulnerability has a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), indicating network attack vector, low attack complexity, and high confidentiality impact without integrity or availability impact. No official patch or remediation level is currently documented, and no known exploits are reported in the wild.
Potential Impact
An attacker with at least Subscriber-level access can read arbitrary files on the affected server by exploiting the path traversal flaw in the template_thumbnail parameter. This can lead to unauthorized disclosure of sensitive information stored on the server. The vulnerability does not impact integrity or availability but has a high confidentiality impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict user privileges to prevent untrusted users from having Subscriber-level or higher access. Monitor official WebFactory communications for updates and apply patches promptly once released.
