Description

The Photo Reviews for WooCommerce plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'wcpr_image_upload_id' parameter in all versions up to, and including, 1.2.30 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The publicly-emitted wcpr_image_upload nonce printed on every product review form is the only gate, and no capability, authentication, or attachment ownership check is performed, allowing the payload to be stored in comment meta — which is not subject to wp_kses — by any unauthenticated visitor; the XSS fires once the review is visible on the frontend.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-100161 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
