CVE-2026-55747 Details
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.
A vulnerability exists in the PocketFlow coding agent cookbook example, specifically within the file-access tools ReadFile, ListFiles, PatchRead, and PatchApply. The issue arises from a helper function that wraps os.path.join without proper canonicalization or containment checks. This oversight allows the function to return absolute paths unchanged, disregarding the intended working directory. As a result, an agent can read or write files outside the designated directory by including absolute paths or traversal sequences in the file-tool arguments.
