SiYuan Affected by Stored XSS via Attribute View Name to Electron Renderer RCE

Summary The kernel stores Attribute View AV / database names without any HTML escape, then a render template uses raw strings.ReplaceAlltpl, "$avName", nodeAvName to embed the name in HTML before pushing to all clients via WebSocket. Three independent client paths render.ts:120 → outerHTML,...

Improper Authentication

github.com/mattermost/mattermost-server is vulnerable to improper authentication. The vulnerability is due to the failure to enforce multi-factor authentication on WebSocket connections, which allows an unauthenticated attacker to access sensitive information through WebSocket events...

GHSA-PF94-94M9-536P Bandit Buffers Unbounded WebSocket Continuation Frames, Allowing Unauthenticated Memory Exhaustion

Summary A single unauthenticated WebSocket client can exhaust server memory in any Bandit-fronted application that accepts WebSocket connections. The fragmented-message reassembly path appends every Continuationfin: false frame's payload to a per-connection iolist with no cumulative size cap, so ...

GHSA-FRH3-6PV6-RC8J Bandit's unbounded WebSocket inflate causes BEAM OOM with a single frame

Summary When a Bandit-fronted server has explicitly enabled WebSocket permessage-deflate compress: true, an unauthenticated client can OOM the BEAM with a single 6 MiB WebSocket frame. Bandit's inflate step has no output-size cap, so a small high-ratio compressed frame e.g. zeros, 1024:1 ratio...
