PraisonAIAgents — Prompt Injection (CVE-2026-40150)
Date: 2026-04
Affected: praison/praisonaiagents
Attack vector: prompt-injection
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2026-40150
CWE: CWE-918
CVSS: 7.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N)

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the web_crawl() function in praisonaiagents/tools/web_crawl_tools.py accepts arbitrary URLs from AI agents with zero validation. No scheme allowlisting, hostname/IP blocklisting, or private network checks are applied before fetching. This allows an attacker (or prompt injection in crawled content) to force the agent to fetch cloud metadata endpoints, internal services, or local files via file:// URLs. This vulnerability is fixed in 1.5.128.
