CVE-2026-57129 is an arbitrary file read vulnerability in the PraisonAI praisonaiagents package affecting MentionsParser handling of @file: mentions. The flaw allows path traversal and absolute-path access outside the intended workspace boundary. When attacker-controlled input is processed as a file mention, the parser can resolve paths that escape workspace_path and read files accessible to the service account. The issue stems from insufficient path validation and unsafe path resolution logic, including acceptance of absolute paths and traversal sequences without enforcing that the final resolved path remains confined to the workspace.
