PYSEC-2026-3532 PraisonAI: IMAP Command Injection via Unsanitized Email Search Parameters

Summary The email search tool in src/praisonai-agents/praisonaiagents/tools/emailtools.py constructs IMAP SEARCH commands by interpolating LLM-controlled parameters fromaddr, subject, query directly into IMAP protocol strings using f-string formatting with double-quote delimiters. An attacker who...

PraisonAI: Webhook signature verification skipped (fail-open) when secret unset, allowing forged inbound webhooks (WhatsApp & Linear bots)

The WhatsApp and Linear bot adapters verify the inbound webhook HMAC signature onlywhen a secret is configured. When the secret environment variable is unset — thedefault on a fresh install and common in development — verification is skipped entirelyand the webhook body is parsed and dispatched a...
