How to Fix CVE-2026-28425

To remediate this vulnerability, upgrade all affected Statamic/cms dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

statamic/cms fixed: 5.73.16
Upgrade statamic/cms to 5.73.16
statamic/cms fixed: 6.7.2
Upgrade statamic/cms to 6.7.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for statamic/cms

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-28425, inspect your project dependencies for Statamic/cms:

inspect dependencies for statamic/cms

Analyze the terminal output to locate any version of Statamic/cms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.73.16), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Statamic/cms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact An authenticated control panel user with access to Antlers-enabled inputs may be able to achieve remote code execution in the application context. That can lead to full compromise of the application, including access to sensitive configuration, modification or exfiltration of data, and potential impact on availability. Exploitation is only possible where Antlers runs on user-controlled content—for example, content fields with Antlers explicitly enabled (requiring permission to configure fields and to edit entries), built-in config that supports Antlers such as Forms email notification settings (requiring configuration permission), or third-party addons that add Antlers-enabled fields to entries (for example, the SEO Pro addon). In each case the attacker must have the relevant control panel permissions. ### Patches This has been fixed in 5.73.16 and 6.7.2. Note that a follow-up report showed that the original 5.73.11 & 6.4.0 fixes were insufficient. If you use addons that depend on Statamic, ensure that after updating you are running a patched Statamic version.
