Imap

A Denial of Service vulnerability, identified as CVE-2026-47241, exists in the Net::IMAP library due to incomplete raw argument validation, potentially allowing an attacker to cause an application crash or unresponsiveness.

A command injection vulnerability (CVE-NONE) exists in PraisonAI's `praisonaiagents` package (versions <= 1.6.48) where unsanitized LLM-controlled parameters are directly interpolated into IMAP SEARCH commands, allowing attackers to craft malicious prompts to inject arbitrary IMAP commands, leading to unauthorized email exfiltration, deletion, or denial-of-service when email tools are configured.

CVE-2026-42257 is a command injection vulnerability in net-imap that could allow an attacker to execute arbitrary commands on a vulnerable system.

A user created a self-hosted email threat detection tool, named VerdictMail, employing IMAP IDLE for real-time monitoring and multi-stage enrichment via SPF, DKIM, DMARC, DNSBL, WHOIS, URLhaus, and VirusTotal, coupled with an LLM for threat assessment.

Maddy Mail Server is vulnerable to LDAP injection via unsanitized username in the `auth.ldap` module, enabling identity spoofing, LDAP directory enumeration, and attribute value extraction by injecting arbitrary LDAP filter expressions through the username field in SMTP submission or IMAP LOGIN interfaces.
