Merge Risk: 🔵 Low · up to e69d4

The manual release workflow may publish before the release PR is reviewed and merged. The workflow is manual-only and gated on secrets, so the risk is bounded, but the ordering should be confirmed before relying on it.

Remove or relocate the public "Security considerations" field.

This field sits in a public issue form. Reporters can enter vulnerability details in it. SECURITY.md says to not report security defects through public issues. The field also has no validations, so it is optional and invites free-text disclosure. Replace it with a markdown element that points to Private Vulnerability Reporting.

Point the security contact link to the repository's advisory page.

The URL https://github.com/LATTIX-IO is the organization page. It does not lead to Private Vulnerability Reporting. The about text tells users to find the Security tab themselves. Use the repository-specific URL https://github.com/LATTIX-IO/<repo>/security/advisories/new. Replace <repo> with the repository name.

Set persist-credentials: false on checkout.

This job runs Cargo build, test, and cargo install steps. These steps can execute third-party build scripts. The default checkout leaves the git token in .git/config, where such code can read it. This job does not push, so it does not need the token. The permissions: contents: read block limits the damage but does not remove the exposure.

🔒 Proposed fix
         with:
           fetch-depth: 0
+          persist-credentials: false

As per coding guidelines, jobs that run dependency-executing build tooling should call actions/checkout with persist-credentials: false. Based on learnings, this matches the zizmor artipacked finding.

Remove the write permissions from the workflow level.

The top-level block grants contents: write and pull-requests: write to every job. This is broader than needed. The release-plz-release job already overrides its own permissions. Set the top-level block to contents: read. Then grant write scopes only in the job that needs them. This matches the zizmor excessive-permissions findings.

Confirm that publishing waits for the release PR merge.

release-plz-release runs immediately after release-plz-pr succeeds. The dependency does not wait for the release PR to merge. If the release job must publish only the merged release PR, use separate triggers or add an explicit merged-PR condition.

Add a conduct reporting contact.

Line 21 sends conduct reports to the private mechanisms in SECURITY.md. That file covers security defects only. It lists no contact for conduct reports. Reporters of harassment have no stated route. Add a conduct contact, such as an email address, to this file or to SECURITY.md.

Deny unknown registries.

unknown-registry = "warn" lets a dependency from an unlisted registry pass the supply-chain gate. The gate is meant to block this case. The unknown-git = "deny" setting on the next line is stricter. Set both to deny.
