Detailsinfo

A vulnerability was found in Statamic CMS up to 5.73.22/6.19.x. It has been classified as problematic. Affected is some unknown processing. The manipulation of the argument visitor-controlled with an unknown input leads to a use of externally-controlled input to select classes or code vulnerability. CWE is classifying the issue as CWE-470. The product uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code. This is going to have an impact on integrity, and availability. CVE summarizes:

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.73.23 and 6.20.0, the fix for CVE-2026-41175 was incomplete. It addressed the issue in the query builder, but the same protection was not applied to in-memory collection sorting. Manipulating sort parameters could result in the loss of content and assets. This requires a front-end template that passes request input into a tag's sort parameter. It is not exploitable by default — a template would need to be explicitly set up to sort by a visitor-controlled value. This has been fixed in 5.73.23 and 6.20.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-49287 since 05/28/2026. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.

Upgrading to version 5.73.23 or 6.20.0 eliminates this vulnerability.
