CVE-2026-56077 PraisonAI CVE debrief

Who should care

Security teams and administrators responsible for PraisonAI installations, particularly those using versions before 1.5.115, should be aware of this vulnerability. Given the high severity and potential for sensitive data exposure, prompt action is recommended to secure affected systems.

Technical summary

The MultiAgentLedger component in PraisonAI before version 1.5.115 does not enforce unique agent IDs. This oversight allows attackers to register agents with duplicate IDs, which can be exploited to share ledger instances. By doing so, attackers can gain access to system prompts and conversation history between agents, leading to information disclosure. The vulnerability is characterized by a CVSS:4.0 vector of AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X, with a CVSS score of 7.1, indicating high severity.

Defensive priority

High

Recommended defensive actions

• Update PraisonAI to version 1.5.115 or later to enforce unique agent IDs.
• Implement additional monitoring to detect suspicious agent registration activities.
• Restrict access to the MultiAgentLedger component to trusted users only.
• Regularly review and update access controls for PraisonAI components.
• Consider implementing a Web Application Firewall (WAF) to detect and prevent exploitation attempts.
• Conduct regular security audits and vulnerability assessments for PraisonAI and related components.
