Solutions

1. Stop calling the removed utility; load image data yourself from a trusted, validated path and pass the bytes or data URI directly.
2. Never resolve user-supplied filesystem paths for image loading; accept URLs or in-memory data instead.

When it happens

Trigger: Raised unconditionally when a removed image utility (previously usable with user-controlled paths) is called; the utility was removed for security reasons.

Common situations: See trigger scenarios.
