GHSA-HXP9-W8X3-P566 Autobahn Python permessage-deflate bypasses maxMessagePayloadSize after inflation

Summary 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...

GHSA-6VMQ-24H2-PJ7J MCP Atlassian: Incomplete path traversal fix allows intra-CWD module overwrite and RCE (bypass of GHSA-xjgw-4wvw-rgm4)

Summary The path traversal fix introduced in v0.17.0 GHSA-xjgw-4wvw-rgm4 is incomplete. validatesafepath is called without an explicit basedir, defaulting to os.getcwd. In standard container deployments the process CWD is the application directory e.g. /app, so paths within that directory,...
