This memory exhaustion condition bypasses maximum message size limits.\n\n## TL;DR\nUnauthenticated remote attackers can exhaust system memory and crash Mailpit by streaming long commands without a newline character to the SMTP or POP3 ports.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-400\n- **Attack Vector**: Network\n- **CVSS**: 5.3\n- **EPSS**: 0.00371 (30.14th percentile)\n- **Impact**: Denial of Service (DoS)\n- **Exploit Status**: Proof of Concept (PoC) available\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- Mailpit SMTP Server\n- Mailpit POP3 Server\n- **mailpit**: < 1.30.4 (Fixed in: `1.30.4`)\n\n## Mitigation\n\n- Upgrade the Mailpit package to version 1.30.4 or higher.\n- Restrict SMTP (port 1025) and POP3 (port 1110) traffic to local development networks or loopback interfaces.\n- Configure container memory limits to prevent host system crashes during memory exhaustion events.\n- Implement automatic process restart policies via systemd or Kubernetes to recover from crashes.\n\n**Remediation Steps:**\n1. Pull the latest Mailpit docker image: docker pull axllent/mailpit:latest\n2. If running local binaries, download v1.30.4 or rebuild using: go install github.com/axllent/mailpit@v1.30.4\n3. Apply firewall configurations restricting access to port 1025 and 1110.\n4. Verify the patch by running the memory consumption proof-of-concept against the updated service.\n\n## References\n\n- [GitHub Security Advisory GHSA-w878-pj84-3j5v](https://github.com/axllent/mailpit/security/advisories/GHSA-w878-pj84-3j5v)\n- [Mailpit Release Tag v1.30.4](https://github.com/axllent/mailpit/releases/tag/v1.30.4)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-67445) -
