CVE intelligence and bounded remediation

CVE-2020-36699 — Quick Page/Post Redirect Project Quick Page/Post Redirect security vulnerability

Medium CVSS 4.3

The Quick Page/Post Redirect Plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on the qppr_save_quick_redirect_ajax and qppr_delete_quick_redirect functions in versions up to, and including, 5.1.9. This makes it possible for low-privileged attackers to interact with the plugin settings and to create a redirect link that would forward all traffic to an external malicious website.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
