State

Graduation rationale

Checks committed plugin hook command values for direct access to browser credential or cookie storage files.

Deterministic signal basis

JsonSignals command-string analysis over ArtifactKind::CursorPluginHooks for browser profile paths such as Chrome or Firefox state directories paired with secret-store files like `Cookies`, `Login Data`, `logins.json`, `key4.db`, `Web Data`, or `Local State`.

Canonical note

Structural stable rule positioned as an explicit threat-review control: high-signal malicious, credential-bearing, or spyware-like behavior that stays opt-in rather than shaping the quiet default.

Why It Matters ​

Browser cookie and credential stores can contain live sessions and saved authentication data, so shared plugin hooks should never access them.

What Triggers ​

SEC694 matches committed plugin hook command values that access browser profile directories together with secret-store files like Cookies, Login Data, logins.json, key4.db, Web Data, or Local State.

False Positives ​

Committed plugin hooks should not inspect browser credential databases. Any legitimate local inspection should be kept outside repo-shared automation.

Remediation ​

Remove browser credential and cookie store access from the committed plugin hook and keep browser profile data outside committed automation.
