CVE-2025-58353

Promptcraft Forge Studio: Complete Sanitizer Bypass Enables XSS via Overlapping Patterns

Promptcraft Forge Studio is a toolkit for evaluating, optimizing, and maintaining LLM-powered applications. All versions of Promptcraft Forge Studio sanitize user input using regex blacklists such as r`eplace(/javascript:/gi, '')`. Because the package uses multi-character tokens and each replacement is applied only once, removing one occurrence can create a new dangerous token due to overlap. The “sanitized” value may still contain an executable payload when used in href/src (or injected into the DOM). There is currently no fix for this issue.

CVE-2025-58361

Promptcraft Forge Studio's incomplete URL check is vulnerable to XSS via SVG

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.
