CVE-2026-56839
Published:July 20, 2026
Updated:August 27, 2026
PraisonAI Code's agent-compatible "CODE_TOOLS" wrappers keep a global workspace root initialized to "None". If an application uses "CODE_TOOLS", "code_read_file", "code_search_replace", or "code_apply_diff" before calling "set_workspace()", the wrappers pass "workspace=None" into lower-level helpers that only enforce path containment when a workspace is truthy. Absolute paths outside the intended project workspace are then read and modified. The official examples correctly call "set_workspace()" before "CODE_TOOLS", and this report does not claim configured workspaces are ineffective. The issue is the fail-open default. PraisonAI's security documentation describes workspace boundaries as the path-traversal protection mechanism, and the already-published Python API arbitrary file write advisory ("GHSA-hvhp-v2gc-268q") was fixed by defaulting an unset workspace to "os.getcwd()". The adjacent read and edit paths reached through "CODE_TOOLS" still fail open.
