Security Risks of Known Vulnerabilities
CVE-2026-77528
CWE-409
Threat level: MEDIUM | CVSS score: 5

Autobahn Python enforces maxMessagePayloadSize against the compressed WebSocket frame length before permessage-deflate inflation, then delivers the inflated message to application callbacks without a second size check. A client frame that is only 22 compressed bytes can inflate to 4096 bytes and reach onMessage even when the application configured a 128-byte message limit, defeating the resource boundary the option is meant to provide.



CVE-2020-35678
