CVE intelligence and bounded remediation
CVE-2026-47092 — Jarrodwatts Claude Hud security vulnerability
Claude HUD through 0.0.12, patched in commit 234d9aa, contains a command injection vulnerability that allows local attackers to execute arbitrary commands by manipulating the COMSPEC environment variable. Attackers can set COMSPEC to an arbitrary binary path before claude-hud performs its version check, causing execFile() to execute the attacker-supplied executable with cmd.exe arguments, resulting in arbitrary code execution on Windows systems.

Matched remediation archetype
Supply-chain, dependency, build, and update integrity
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace affected packages, source archives, build actions, plugins, installers, and updates from declared source to deployed artifact.
- Confirm provenance, signatures or digests, namespace ownership, lockfile resolution, registry configuration, and build-runner trust boundaries.
- Inventory direct, transitive, vendored, generated, and bundled copies across releases and distribution channels.
Remediate safely
- Move to a maintained trusted artifact or remove the dependency; pin immutable identities and verify provenance and integrity before use.
- Regenerate lockfiles and artifacts in a clean isolated build, minimize build credentials and network access, and produce an updated software bill of materials.
- Require reviewed update policy, protected publishing, and reproducible or independently attestable builds where supported.
