Affected packages
• npm next: >= 0.9.9, < 14.2.31 → fixed in 14.2.31
• npm next: >= 15.0.0, < 15.4.5 → fixed in 15.4.5
Description
A vulnerability in Next.js Image Optimization has been fixed in v15.4.5 and v14.2.31. When images returned from API routes vary based on request headers (such as `Cookie` or `Authorization`), these responses could be incorrectly cached and served to unauthorized users due to a cache key confusion bug.
All users are encouraged to upgrade if they use API routes to serve images that depend on request headers and have image optimization enabled.
