CVE-2026-30345Public exploitNetwork attack vector

Arbitrary file write via unchecked archive paths

Published Mar 18, 2026 · Updated Mar 18, 2026

Relative path traversal in CTFd before 3.8.2 allows remote authenticated users to write arbitrary files through a crafted admin import. The import_ctf routine processes archive member paths without constraining their resolved destinations to the extraction directory. Administrative access and the filesystem uploader are required; the provided Docker Compose deployment can run CTFd as root, making code execution possible.
