fix-cve

fix-cve is a skill for Claude Code from openshift-eng/ai-helpers. It costs 100 tokens per session (2,267 once invoked), scanned A, original, Apache-2.0.

A guided way to patch a Go module that contains a known CVE, a publicly recorded security vulnerability. It chooses between upgrading the dependency, replacing it with a patched fork, or applying a patch based on Go-version compatibility.

In plain words
What is it for?
Use it to fix a named CVE in a Go project, update a module to a fixed version, switch to a patched fork, or apply a security patch across modules.
Why use it?
It removes the guesswork from fixing a vulnerable dependency while limiting changes to what the project needs. It also handles projects with multiple go.mod files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fix-cve scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

fix-cve

Patch a Go module dependency to fix a CVE. The skill determines the right strategy based on Go version compatibility between the project and the fix, then applies the minimum changes needed.

Parameters

  • module (required): The Go module to patch, e.g. google.golang.org/grpc
  • fix-version (required): The upstream version that contains the CVE fix, e.g. v1.75.1 — or a URL to the release/advisory with version info
  • cve (required): The CVE identifier, e.g. CVE-2026-33186
  • ticket (required): The Jira/bug ticket, e.g. OCPBUGS-83972

If any required parameter is missing, ask the user before proceeding.

Strategy selection

The fix follows one of three paths depending on Go version compatibility. Determine which path to take BEFORE making any changes.

Gather version info

  1. Read the project's Go version from the root go.mod (go directive), e.g. go 1.23.6
  2. Determine the Go version required by the CVE fix. Either:
    • Fetch the upstream fix version's go.mod to check its go directive
    • Parse it from the release page or advisory the user provided
  3. Extract the major.minor from both (e.g. 1.23 from go 1.23.6)

Path A: Direct upstream update (project Go >= fix Go)

Condition: The project's Go version is equal or higher than what the fix requires. The fix can be applied by simply updating the dependency to the upstream version that contains the patch.

Example: Project uses go 1.25.0, fix requires go 1.23.1 → direct update works.

Action: Update the module version in go.mod to the fix version (or latest patched version), then follow the standard update workflow (Step 3 onwards).

Path B: Bump Go patch version (same minor, lower patch)

Condition: The project's Go is on the same minor version as the fix but a lower patch. Bumping the patch version (Z in X.Y.Z) within go.mod is safe enough to unlock the fix.

Example: Project uses go 1.23.1, fix requires go 1.23.7 → bump to go 1.23.7 in go.mod and update the dependency.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
