fix(docker): bump Bun to 1.4.4 for Node2Shell (CVE-2026-111497) - #27

Conversation
Bun 1.4.4 updates its bundled brotli from v1.2.0 to v1.2.1, which fixes the Node2Shell decoder RCE (CVE-2026-111497) reachable through node:zlib, DecompressionStream and compressed fetch responses (oven-sh/bun#46392). Bun 1.4.3 and earlier remain affected. squawk polls third-party status pages over fetch, so a malicious or compromised status page could serve a crafted Brotli response.

Why
squawk runs on
oven/bun:1.4.0-alpine. Bun versions before 1.4.4 bundle brotli v1.2.0, whose decoder has Node2Shell (CVE-2026-111497), a memory-safety bug that can lead to remote code execution when attacker-controlled Brotli data is decompressed.squawk polls third-party status pages (Statuspage.io and incident.io) over
fetch, which decompressesContent-Encoding: brresponses automatically. A malicious or compromised status page could therefore reach the vulnerable decoder.Change
Dockerfile:oven/bun:1.4.0-alpine→oven/bun:1.4.4-alpine(the tag publishes both amd64 and arm64).Bun 1.4.4 updates brotli to v1.2.1, which includes the decoder fix (oven-sh/bun#46392).
This supersedes Dependabot's #26, which only goes to 1.4.3, a version that is still vulnerable.
