CVE-2026-33160
Craft CMS may expose private assets through anonymous "generate transform" calls via transform URL
描述
### Summary An unauthenticated user can call `assets/generate-transform` with a private `assetId`, receive a valid transform URL, and fetch transformed image bytes. The endpoint is anonymous and does not enforce per-asset authorization before returning the transform URL. ### Details Root cause: - Anonymous endpoint accepts user-controlled asset reference. - It creates and returns a transform URL for that asset without checking access rights. - If the transform output is reachable, guest users can read content derived from private assets. Who is impacted: - Installations where private source assets can be transformed and transform URLs are reachable. Security consequence: - Anonymous users can obtain content derived from private assets without authentication. ### Resources https://github.com/craftcms/cms/commit/7290d91639e
