Undertow
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
A side-by-side editorial comparison of Libreswan and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
IPsec daemon shipping back-to-back CVE releases, one of them found by an AI audit.
Libreswan is an IKE/IPsec implementation, and its recent visible releases are entirely security-driven: 5.3.1 addressed three CVEs, and 5.3.2 followed a month later with a single one. The 5.3.2 note discloses that the project ran an AI-assisted audit of its own codebase, which surfaced an assertion failure reachable through a malformed X.509 certificate in FIPS mode. The older entries in this feed are raw commit-log dumps from the 4.x and 5.0rc era rather than curated notes.
Sanity is paying down its runtime weight while wiring agents into the content layer.
Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.

The project is auditing itself more aggressively than its release cadence suggests, and the parsing paths — certificate handling, IKEv1 proposal defaults — are where the findings keep landing. The 5.0 work visible here was a deliberate tightening of IKEv1 cryptosuite defaults, and the current CVE stream is the same instinct applied to inputs an attacker controls.
Further findings from the same audit path would surface as additional point releases against certificate and packet parsing; the entries do not indicate whether the audit is complete.

The MCP server is being hardened into a supervised write path rather than a read-only convenience: patches roll back as a unit, malformed IDs are rejected up front, and schema deploys now refuse to touch a Studio-managed workspace even when stale state says otherwise. That last rule is the direction in miniature — agents are being given real write access, fenced off by workspace ownership. Meanwhile the frontend packages are absorbing a breaking release to make bundle size a property of what you import rather than what ships.
The v4.0.0 notes state that more components move off runtime CSS-in-JS across the 4.x minors, so the bundle work continues incrementally rather than in another breaking jump. On the SDK side the presence release explicitly defers rendered remote selections to a forthcoming Portable Text plugin — the most concretely signposted next item in the feed.
