CVE-2026-86787Network attack vector

Contributor-level code execution via unchecked template references

Published Oct 14, 2026 · Updated Oct 14, 2026

Code execution in affiliate-toolkit before 3.9.1 allows remote authenticated users to run arbitrary PHP through template rendering. The renderer accepts arbitrary post IDs and passes their atkp_template_body custom field to BladeOne for PHP compilation and execution without restricting references to administrator-controlled templates. Contributor-level access is sufficient; execution occurs on the WordPress server rather than in a browser.
