CVE-2019-19915 — Webfactoryltd 301 Redirects security vulnerability

Critical CVSS 9

The "301 Redirects - Easy Redirect Manager" plugin before 2.45 for WordPress allows users (with subscriber or greater access) to modify, delete, or inject redirect rules, and exploit XSS, with the /admin-ajax.php?action=eps_redirect_save and /admin-ajax.php?action=eps_redirect_delete actions. This could result in a loss of site availability, malicious redirects, and user infections. This could also be exploited via CSRF.

Privilege escalation and unsafe privilege management

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

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
