Improper CSP in Image Optimization API for Next.js versions between 10.0.0 and 12.1.0
Next.js is a React framework. Starting with version 10.0.0 and prior to version 12.1.0, Next.js is vulnerable to User Interface (UI) Misrepresentation of Critical Information. In order to be affected, the next.config.js
file must have an images.domains
array assigned and the image host assigned in images.domains
must allow user-provided SVG. If the next.config.js
file has images.loader
assigned to something other than default, the instance is not affected. Version 12.1.0 contains a patch for this issue. As a workaround, change next.config.js
to use a different loader configuration
other than the default.
Impact
- Affected: All of the following must be true to be affected
- Next.js between version 10.0.0 and 12.0.10
- The
next.config.js
file has images.domains array assigned - The image host assigned in images.domains allows user-provided SVG
- Not affected: The

Patches

Or if you want to use the loader
prop on the component, you can use custom
