Authenticated context disclosure via duplicate agent IDs
Published Jun 18, 2026 · Updated Jun 18, 2026
Information disclosure in PraisonAI before 1.5.115 allows remote authenticated users to read agent prompts and history through duplicate IDs. MultiAgentLedger keys a shared dictionary by agent ID without enforcing uniqueness, so a duplicate registration returns the victim's existing ledger. Low-privilege agent registration is required, and exposure is limited to context stored under the collided identifier.
