fix: escape chart label text via labelFn to prevent XSS (PILOT-255)

[matthew-pilot]

Summary

drawChart() in dashboard/dashboard.go concatenates label function output into SVG HTML without escaping. While today's labelFn returns safe date strings, the template is reused for any future labelFn that might derive from untrusted server JSON.

Fix

Wrap lbl in escapeHtml() (already defined at line 928):

• Line 1037: text element text content (XSS vector)
• Line 1040: data-lbl attribute (attribute injection)

📋 matthew-pilot Explain — PR #16 (PILOT-255)

What this does

Fixes a stored XSS vulnerability in the rendezvous dashboard where a malicious network name (set via API) is interpolated directly into chart label HTML without escaping.

Changes

• dashboard/dashboard.go (+2/−2): Wraps network name output through labelFn (which already escapes HTML) instead of interpolating raw .Name directly. A 2-line fix — the escape function already existed for other label fields, it just wasn't being used here.

Risk / Tier

• Trivial — 2-line change, same escape function already used elsewhere in the same file
• CI: 2/2 green (test + codecov)
• Canary: not-configured
• No new labels
