CVE-2026-115938 · Severity: high · CVSS 8.8 · Published 2026-10-23

Craft CMS is a web-based content management system. An authenticated control panel user can exploit a template injection vulnerability to leak the application's security key, then forge signed requests to execute arbitrary PHP code. This allows account takeover, data theft, or full site compromise by a user with basic admin access.

## Technical details

A two-stage vulnerability: first, an authenticated user submits an element-search condition with a crafted element selector that bypasses Twig's SecurityPolicy sandbox by using Yii's ArrayHelper for property lookup, leaking the security key via a character-oracle side channel. Second, the attacker forges HMAC-signed parameters and passes them to View::renderObjectTemplate(), which evaluates untrusted Twig templates outside the sandbox, allowing PHP code execution through Twig's string-callable form.
