CVE-2025-8482 — The Simple Local Avatars plugin for WordPress is vulnerable to unauthorized modification of data in version 2.8.4

Medium CVSS 4.3

The Simple Local Avatars plugin for WordPress is vulnerable to unauthorized modification of data in version 2.8.4. This is due to a missing capability check on the migrate_from_wp_user_avatar() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to migrate avatar metadata for all users.

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.
