Lifecycle Timeline
3DescriptionCVE.org
PraisonAI before 1.5.115 contains a path traversal vulnerability in MultiAgentMonitor that fails to sanitize agent IDs when building file paths. Attackers can include traversal sequences like ../ in agent IDs to read, write, or overwrite arbitrary files, enabling sensitive disclosure, denial of service, or code execution.
AnalysisAI
Path traversal in PraisonAI's MultiAgentMonitor component (versions <= 1.5.114) lets remote attackers who can supply agent identifiers read, write, or overwrite arbitrary files on the host by embedding '../' sequences in agent IDs. The flaw, disclosed by VulnCheck and tracked as GHSA-766v-q9x3-g744, enables information disclosure, denial of service, and potential code execution in multi-agent AI deployments; no public exploit identified at time of analysis but a detailed PoC is included in the advisory.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to control or influence the agent ID string passed to MultiAgentMonitor (and/or MultiAgentLedger) - for example a web frontend, API, or chat interface that accepts user-chosen agent identifiers and forwards them to PraisonAI without filtering. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H) scores 8.7 and reflects a network-reachable, low-complexity, low-privilege flaw with high impact on confidentiality, integrity, and availability - consistent with arbitrary file read/write leading to possible code execution. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker interacting with a PraisonAI-backed application supplies an agent ID such as '../../../../etc/cron.d/pwn' (or a Windows equivalent), causing MultiAgentMonitor to write attacker-controlled monitor content outside base_path; on a host where that path is executed by a privileged process, this escalates to code execution, while pointing the ID at sensitive files like SSH keys or application configs yields information disclosure. The advisory publishes a working PoC, so weaponization effort is low for any deployment exposing agent ID creation to untrusted callers. |
| Remediation | Vendor-released patch: upgrade praisonaiagents to 1.5.115 or later (pip install --upgrade praisonaiagents), per GHSA-766v-q9x3-g744. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all systems running PraisonAI ≤1.5.114 and determine if MultiAgentMonitor is exposed to untrusted networks; document current file system permissions and access controls. …
