Security Risks of Known Vulnerabilities
CVE-2026-42304
CWE-400
Threat level: HIGH | CVSS score: 8

The twisted.names module is vulnerable to a Denial of Service (DoS) attack via resource exhaustion during DNS name decompression. A remote, unauthenticated attacker can exploit this by sending a crafted TCP DNS packet containing deeply chained compression pointers. This flaw bypasses previous loop-prevention logic, causing the single-threaded Twisted reactor to hang while processing millions of recursive lookups, effectively freezing the server.


Threat level: MEDIUM | CVSS score: 5
