AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N
Network-accessible server with no authentication on any route; high integrity from unrestricted agent pipeline injection, low confidentiality from /info metadata leakage only.

Lifecycle Timeline

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, AgentServer exposes ServerConfig.auth_token but AgentServer._create_app does not check it on any route. A remote caller can subscribe, publish, and perform other actions without a valid bearer token or X-Auth-Token even when authentication is configured. This issue is fixed in version 1.6.58.
AnalysisAI
Authentication bypass in PraisonAI's AgentServer component exposes all routes - /publish, /events, /info, /health - to unauthenticated remote callers, even when operators have explicitly configured an auth_token in ServerConfig. The AgentServer._create_app factory never reads or enforces the configured token, rendering it dead code while /info actively misleads operators by displaying it as masked ('*'), creating a false sense of security. …

Vulnerability AssessmentAI
| Exploitation | No special conditions are required beyond network reachability of the AgentServer instance - the bypass applies unconditionally to all routes (/info, /publish, /events, /health) regardless of whether auth_token is set in ServerConfig. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N) accurately reflects the severity: network-reachable, zero authentication required, no user interaction, and high integrity impact from unrestricted agent pipeline injection. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade praisonaiagents to version 1.6.58 or later via pip install --upgrade praisonaiagents. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all internet-exposed PraisonAI deployments and assess whether they handle sensitive agent operations; consider immediate network isolation or firewall restrictions for critical systems. …
