CVE-2026-77757Network attack vector

Authenticated file exposure and deletion via image path

Published Aug 26, 2026 · Updated Aug 26, 2026

Path traversal in Directorist 8.5 through 8.9.2 allows remote authenticated users to move server-readable image files via REST listing submission. The REST v2 listing-submission handler accepts a caller-supplied image reference as the source path for a file move without constraining it to the intended upload directory. Subscriber-level access is sufficient; successful use exposes the relocated image in a public directory and deletes the original file.
