CVE-2026-57120 Details
Description
PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.59, execute_code sandbox mode permits runtime assembly of blocklisted dunder names and allows str.format or str.format_map to resolve dotted fields through C-level attribute access that bypasses _safe_getattr. This exposes class, qualified-name, base-class, globals, and object-dictionary attributes to prompt-influenced code when approval is automatically granted, producing a high-impact read primitive without establishing a complete in-process execution chain. This issue is fixed in praisonaiagents 1.6.59.
A vulnerability exists in the PraisonAI multi-agent system, specifically in the execute_code tool's sandbox mode, prior to version 1.6.59. This vulnerability allows the runtime assembly of blocklisted dunder names and enables access to certain class attributes through C-level attribute resolution, bypassing the intended safety measures. As a result, sensitive attributes can be exposed to code influenced by user prompts, creating a significant security risk.
Users can update to PraisonAI version 1.6.59 or later, where this vulnerability has been fixed.
