+## Known Low-Severity Vulnerabilities
+
+### GHSA-848j-6mx2-7j84 (elliptic)
+
+**Severity:** High (but not exploitable in this plugin's context)
+
+**Affected component:** `elliptic` (transitive, via `vite-plugin-node-polyfills` → `node-stdlib-browser` → `crypto-browserify` → `browserify-sign`)
+
+**Description:** The elliptic library used in this plugin's development dependencies contains a prototype pollution vulnerability. This plugin is a **read-only** Headlamp plugin that never executes any cryptographic operations at runtime. The vulnerable code path requires:
+- Use of `elliptic` curve operations on untrusted input, AND
+- Ability for an attacker to influence the `elliptic` curve key generation input
+
+Neither condition is met in this plugin's runtime context.
+
+**Remediation:** No patched version of `elliptic` exists on npm. The current override in `package.json` (`"elliptic": ">=6.6.1"`) is a placeholder — no resolvable version satisfies this constraint.
+
+**Risk acceptance rationale:**
+1. Plugin has no write operations against the cluster
+2. All data flows through Headlamp's API proxy with standard RBAC enforcement
+3. The vulnerable dependency is only in the development/build toolchain, not runtime
+4. No untrusted input can reach `elliptic` curve operations through this plugin
+
+**Review date:** 2026-05-05
