Vulnerability Title
PocketFlow - Path Traversal in pocketflow-coding-agent Cookbook Example File Tools
Source: CVE Program / CVE List V5
Vulnerability Description
The pocketflow-coding-agent cookbook example in The-Pocket/PocketFlow implements a helper as a thin os.path.join(workdir, p) wrapper with no canonicalization or containment check, used unguarded by the ReadFile, ListFiles, PatchRead, and PatchApply file-access tools. Severity reflects that this affects an illustrative cookbook example rather than a core library API; applications that copy this pattern into production are affected.
