Lifecycle Timeline
5DescriptionGitHub Advisory
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.
AnalysisAI
Server-side request forgery in PraisonAIAgents multi-agent system allows authenticated attackers to force internal network reconnaissance and data exfiltration through unvalidated URL crawling. The web_crawl() function in versions prior to 1.5.128 accepts arbitrary URLs from AI agents without scheme allowlisting, hostname blocking, or private network checks, enabling access to cloud metadata endpoints (AWS/Azure/GCP), internal services, and local filesystems via file:// URIs. …

Vulnerability AssessmentAI
| Exploitation | Requires authenticated access to PraisonAIAgents versions prior to 1.5.128 with ability to control AI agent prompts or inject URLs into crawled content. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.7 reflects high confidentiality impact via SSRF; authenticated agents bypass URL validation to access metadata endpoints and internal services. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Attacker injects prompt directing AI agent to crawl http://169.254.169.254/latest/meta-data (AWS) or internal service URL. Agent's web_crawl() function lacks hostname validation, fetches request unauthenticated to internal network, exfiltrates credentials or service config. … |
| Remediation | Vendor-released patch: version 1.5.128 implements URL validation controls including scheme allowlisting and private network filtering. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all deployments of PraisonAIAgents and identify current versions; audit access logs for suspicious web_crawl() activity targeting 127.0.0.1, 169.254.169.254 (AWS metadata), or internal hostnames. …
