PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.59, src/praisonai-agents/praisonaiagents/tools/email_tools.py interpolates LLM-controlled from_addr, subject, and query values directly into quoted IMAP SEARCH criteria. Embedded quote, backslash, newline, or null characters can escape the intended criterion and alter IMAP operations when search_emails, reply_email, or archive_email is exposed to an agent with configured email credentials, allowing mailbox data access, modification, deletion, or connection disruption. This issue is fixed in praisonaiagents 1.6.59.

Affected: PyPI: praisonaiagents

## Summary

The email search tool in `src/praisonai-agents/praisonaiagents/tools/email_tools.py` constructs IMAP SEARCH commands by interpolating LLM-controlled parameters (from_addr, subject, query) directly into IMAP protocol strings using f-string formatting with double-quote delimiters. An attacker who can influence the arguments to the `search_emails` or `reply_email` tool (via crafted agent prompts) can inject arbitrary IMAP commands, potentially exfiltrating email data from other folders, deleting emails, or performing other unauthorized IMAP operations. ## Details

**Vulnerable code (lines 493–502):** ```python criteria = [] if from_addr: criteria.append(f'FROM "{from_addr}"') if subject: criteria.append(f'SUBJECT "{subject}"') if query: criteria.append(f'TEXT "{query}"') if not criteria: criteria.append("ALL") search_str = " ".join(criteria) status, data = mail.search(None, search_str) ```

The `from_addr`, `subject`, and `query` parameters originate from LLM tool call arguments (the `search_emails` public function at line 665). These values flow through without any sanitization or escaping. The double-quote (`"`) characters in these parameters allow breaking out of the IMAP SEARCH quoted string context.

**Additional injection points:** - Line 416: `mail.search(None, f'HEADER Message-ID "{search_id}"')` - Line 447: Same pattern in `_smtp_reply_email` - Line 542: Same pattern in `_smtp_archive_email`

The `search_id` / `message_id` parameter in these…
