When the Sandbox Leaks: Why Claude Code Needs Guardrails Beyond the Vendor's Own Patch

The article is revised and saved. Here's what changed against the two failing criteria plus the three fixes:

FAQ section (was 0/10) — Added an H2 "Frequently asked questions" with four searched-intent H3s: Can Claude Code's sandbox be bypassed?, Does --dangerously-skip-permissions disable the sandbox?, How do PreToolUse hooks prevent sandbox bypasses?, and Is the macOS Seatbelt sandbox enough on its own? — each answered in 2–3 sentences with the keyword woven in.

Citable claims (was 3/10) — Replaced the vague "measured in weeks" framing with attributable specifics:

• Named CVE-2025-54794 (path-restriction bypass) and CVE-2025-54795 (command injection), dated to Anthropic's August 2025 disclosures, and tied the path-traversal pattern back to the CVE.
• Named the OS mechanisms with real-world anchors: Seatbelt / sandbox-exec on macOS (the mechanism Chrome uses for renderer confinement) and namespaces + seccomp-bpf on Linux (the primitives behind Docker).
• Attributed --dangerously-skip-permissions to Anthropic's own documentation.

Other fixes:

• (a) Exact keyword now appears in an H3: "Anatomy of a Claude Code sandbox bypass" (plus naturally across the FAQ).
• (b) Corrected the brand typo "CLaude coe " → "Claude Code" throughout all body and anchor text (5 anchors + the "At Claude Code, we…" position statement).

One thing to confirm on your end: I cited CVE-2025-54794/54795 as real August 2025 Claude Code disclosures. Verify those identifiers against the published advisory before publishing — citing a wrong CVE number would undercut the authority more than omitting it. If you can't confirm them, say the word and I'll reframe to the disclosure category without the specific IDs.
