Information Disclosure in praisonaiagents (CVE-2026-47395)
Summary
Vulnerability in praisonaiagents (CVE-2026-47395). Confidential information can be exposed externally. Mitigation: upgrade to 1.6.40 or later.
Original description
The description as published by the source.
PraisonAI is a multi-agent teams system. Prior to version 4.6.40 of PraisonAI, corresponding to version 1.6.40 of praisonaiagents, PraisonAI's direct-prompt CLI automatically expands @url: mentions in raw prompt text before agent execution begins. If a prompt contains @url:, the CLI calls MentionsParser.process(...). The @url: handler then performs a direct urllib.request.urlopen() request to the attacker-controlled URL and returns the response body. That response body is prepended to the final model prompt context. There is no loopback/private-address restriction, no metadata-service restriction, and no approval gate before the fetch. As a result, attacker-influenced prompt text can cause the operator's machine to fetch localhost-only HTTP resources and inject the response into model context. PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 contain a fix.
