Short explanation
CVE-2026-119762 is an unauthenticated denial of service vulnerability in Axigen Mail Server caused by unbounded nesting depth when parsing SOAP/XML and JSON request bodies. This flaw allows unauthenticated attackers to send a single deeply nested request, exhausting the stack and repeatedly crashing SMTP, IMAP, POP3, and web services.
This vulnerability threatens system availability by allowing remote attackers to repeatedly crash critical mail and web services without requiring authentication.
What should be done?
- Follow vendor advisories to review updates
- Consult guidance provided by official sources
- Apply available updates for affected versions
