CVE-2024-13556Network attack vector

Conditional code execution via unauthenticated export deserialization

Published Feb 18, 2025 · Updated Apr 8, 2026

PHP object injection in wecantrack Affiliate Links 3.0.1 and earlier allows remote attackers to inject objects through imported export data. The import path deserializes attacker-controlled file-export content without requiring authorization or restricting object creation. Impact requires a POP chain from another installed plugin or theme; the resulting gadget chain can read data, delete files, or execute code.
