CRITICAL 9.3

DescriptionNVD

Promptcraft Forge Studio is a toolkit for evaluating, optimizing, and maintaining LLM-powered applications. All versions contain an non-exhaustive URL scheme check that does not protect against XSS. User-controlled URLs pass through src/utils/validation.ts, but the check only strips javascript: and a few patterns. data: URLs (for example data:image/svg+xml,…) still pass. If a sanitized value is used in href/src, an attacker can execute a script. There is currently no fix for this issue.
