DescriptionGitHub Advisory

Craft is a platform for creating digital experiences. In Craft versions from 4.0.0-RC1 to before 4.17.0-beta.1 and 5.9.0-beta.1, there is a Privilege Escalation vulnerability in Craft CMS’s GraphQL API that allows an authenticated user with write access to one asset volume to escalate their privileges and modify/transfer assets belonging to any other volume, including restricted or private volumes to which they should not have access. The saveAsset GraphQL mutation validates authorization against the schema-resolved volume but fetches the target asset by ID without verifying that the asset belongs to the authorized volume. This allows unauthorized cross-volume asset modification and transfer. This vulnerability is fixed in 4.17.0-beta.1 and 5.9.0-beta.1.

AnalysisAI

Craft CMS versions 4.0.0-RC1 to 4.17.0 and 5.0 to 5.9.0 contain a privilege escalation vulnerability in the GraphQL API that allows authenticated users with write access to one asset volume to modify or transfer assets across any other volume, including restricted ones they should not access. The vulnerability stems from insufficient authorization validation in the saveAsset mutation, which verifies permissions against the intended volume but fails to confirm the target asset actually belongs to that volume. An attacker with limited asset write permissions can exploit this to gain unauthorized access to and manipulate sensitive assets in protected volumes.
