CVE-2026-39889

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the A2U Agent-to-User event stream server in PraisonAI exposes all agent activity without authentication. The createa2uroutes function registers the following endpoints with NO authentication checks: /a2u/info, /a2u/subscribe,...

CVE-2026-39890

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed,...

CVE-2026-39891

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the createagentcentrictools function returns tools like acpcreatefile that process file content using template rendering. When user input from agent.start is passed directly into these tools without escaping, template expressions in the...

CVE-2026-39888

PraisonAI is a multi-agent teams system. Prior to 1.5.115, executecode in praisonaiagents.tools.pythontools defaults to sandboxmode="sandbox", which runs user code in a subprocess wrapped with a restricted builtins dict and an AST-based blocklist. The AST blocklist embedded inside the subprocess...

CVE-2026-39891 PraisonAI has a Template Injection in Agent Tool Definitions

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the createagentcentrictools function returns tools like acpcreatefile that process file content using template rendering. When user input from agent.start is passed directly into these tools without escaping, template expressions in the...

CVE-2026-39891

PraisonAI’s multi-agent system contains a template injection in the create_agent_centric_tools() function prior to version 4.5.115. Tools such as acp_create_file process file content via template rendering, and user input from agent.start() could be rendered as template expressions instead of bei...

CVE-2026-39890 PraisonAI Affected by Remote Code Execution via YAML Deserialization in Agent Definition Loading

PraisonAI is a multi-agent teams system. Prior to 4.5.115, the AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed,...

CVE-2026-39890

Prais onAI’s AgentService.loadAgentFromFile parses YAML with js-yaml without disabling dangerous tags (e.g., !!js/function, !!js/undefined), enabling attacker to upload a malicious agent definition and achieve remote code execution on the server. Affected software: PraisonAI (before 4.5.115). Roo...
