CVE-2026-40154 Details
Description
PraisonAI is a multi-agent teams system. Prior to 4.5.128, PraisonAI treats remotely fetched template files as trusted executable code without integrity verification, origin validation, or user confirmation, enabling supply chain attacks through malicious templates. This vulnerability is fixed in 4.5.128.
A vulnerability in PraisonAI prior to version 4.5.128 allows untrusted remote template files to be treated as executable code without proper integrity verification, origin validation, or user consent. This flaw enables supply chain attacks by executing malicious code from downloaded templates, with full access to the user's environment, filesystem, and network. The issue arises when templates are fetched from remote sources, such as GitHub, and automatically executed without any safety checks or user interaction.
Users are advised to verify the integrity of templates before use, require user confirmation for executing remote template code, and avoid automatic execution of 'tools.py' unless explicitly enabled by the user. In the short term, templates can be run in a sandboxed environment with restricted access and only from trusted sources.
