SCA: security update for craftcms/cms (GHSA-6fx5-5cw5-4897)

medium Tenable Self-Hosted Container Security Plugin ID 437932

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through
 5.8.22, a Time-of-Check-Time-of-Use (TOCTOU) race condition exists in Craft CMS’s token validation service
 for tokens that explicitly set a limited usage. The `getTokenRoute()` method reads a token’s usage count,
 checks if it’s within limits, then updates the database in separate non-atomic operations. By sending
 concurrent requests, an attacker can use a single-use impersonation token multiple times before the
 database update completes. To make this work, an attacker needs to obtain a valid user account
 impersonation URL with a non-expired token via some other means and exploit a race condition while
 bypassing any rate-limiting rules in place. For this to be a privilege escalation, the impersonation URL
 must include a token for a user account with more permissions than the current user. Versions 4.16.19 and
 5.8.23 patch the issue. (CVE-2026-27128)
