What is CVE-2026-56077?

The MultiAgentLedger component of PraisonAI versions before 1.5.115 is susceptible to an information disclosure flaw. This vulnerability allows attackers to exploit the system by registering agents with duplicate IDs, which undermines the enforcement of unique agent identifiers. As a result, these malicious actors can share ledger instances between agents, potentially exposing sensitive system data such as prompts and conversation histories. This exposure could lead to unauthorized access to critical information, emphasizing the need for immediate attention and remediation.
