CVE-2025-12182: Qi Blocks <= 1.4.3 - Missing Authorization to Arbitrary Attachment Resize

• Severity: medium (CVSS 4.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-11-15 · updated 2026-10-07
• Weakness: CWE-284

Description

The Qi Blocks plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the `resize_image_callback()` function in all versions up to, and including, 1.4.3. This is due to the plugin not properly verifying that a user has permission to resize a specific attachment. This makes it possible for authenticated attackers, with Contributor-level access and above, to resize arbitrary media library images belonging to other users, which can result in unintended file writes, disk consumption, and server resource abuse through processing of large images.
