CVE-2026-71204 (GCVE-0-2026-71204)

Vulnerability from cvelistv5 – Published: 2026-08-05 06:59 – Updated: 2026-08-05 13:16

Title

changedetection.io: Omitted Checkbox in /settings Save Silently Disables API Key Enforcement

Summary

changedetection.io's /settings save handler builds an update dict from form.data['application'] and blind-merges it into the stored application settings via .update(). Because WTForms represents an unchecked checkbox as False rather than 'unchanged', and only the 'password' field is special-cased against this problem, a POST to /settings that omits the api_access_token_enabled field (e.g. a minimal scripted request) silently disables API key enforcement for the entire REST API, exposing the full watch list, history, and configuration to unauthenticated requests.

Severity

6.3 (Medium)
