Technical details
The plugin insufficiently sanitizes the `feedConfigCustom2` parameter, applying only `wp_unslash()` before storage, then passes template expressions containing `{(return ...)}` directly to PHP's `eval()` during feed generation without code-level sanitization. An authenticated attacker with Shop Manager-level or higher privileges can inject arbitrary PHP code through the Custom2 template feature, which is enabled by default via the `ctxfeed_custom2_eval_enabled` option.
Affected products
