CVE-2026-54816Network attack vector

Contributor-level code execution via shortcode ad_args

Published Jun 17, 2026 · Updated Jun 17, 2026

Code injection in Advanced Ads 2.0.21 and earlier allows remote authenticated users to execute server-side code through the ad_args shortcode parameter. The shortcode handler accepts attacker-controlled ad_args values and processes them as executable ad arguments without blocking code-bearing input. Contributor-level access is required, and successful exploitation executes code in the WordPress server context.
