Technical details
The plugin fails to properly sanitize input in the 'lsd[remark]' parameter and does not escape output, allowing authenticated users to inject arbitrary JavaScript. An AJAX handler that creates listings omits capability checks, making the vulnerability exploitable by subscriber-level users who can obtain the nonce from pages displaying the [listdom-dashboard] shortcode. The injected scripts execute in the browser of any user who views the affected listing.
Affected products
- Automattic Listdom up to and including 6.1.1
