Threats affecting pkg:pypi/praisonai

PraisonAI versions 4.5.138 and earlier are vulnerable to arbitrary code execution due to automatic, unsanitized import of a local tools.py file at startup. This allows an attacker with write access to the working directory to execute arbitrary Python code within the PraisonAI process and potentially compromise the host system and connected data. The vulnerability is fixed in version 4.5.139.

PraisonAI is a multi-agent teams system. Prior to 4.5.128, the Flask API endpoint in src/praisonai/api.py renders agent output as HTML without effective sanitization. The _sanitize_html function relies on the nh3 library, which is not listed as a required or optional dependency in pyproject.toml. When nh3 is absent (the default installation), the sanitizer is a no-op that returns HTML unchanged. An attacker who can influence agent input (via RAG data poisoning, web scraping results, or prompt injection) can inject arbitrary JavaScript that executes in the browser of anyone viewing the API output. This vulnerability is fixed in 4.5.128.
