CVE-2026-77814

ispathtrusted in scripts/iib/api.py compares the requested path against each allowed parent directory with path.startswithparentpath, without appending a path separator. A directory whose name merely begins with an allowed path therefore satisfies the comparison, so where /data/images is allowed ...

CVE-2026-77814

Infinite Image Browsing , a Stable Diffusion WebUI extension, contains a path traversal flaw in is_path_trusted (scripts/iib/api.py). The function uses path.startswith(parent_path) without appending a path separator, so a directory whose name merely begins with an allowed path (e.g., /data/images...
