Description

Important

This vulnerability only affects sites which are in the "dev" environment mode. If your production website is in "dev" mode, it has been misconfigured, and you should immediately swap it to "live" mode.
See https://docs.silverstripe.org/en/developer_guides/debugging/environment_types/ for more information.

If a website has been set to the "dev" environment mode, a URL can be provided which includes an XSS payload which will be executed in the resulting error message.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
