CVE-2024-12467: Pago por Redsys <= 1.0.12 - Reflected Cross-Site Scripting

The Pago por Redsys plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'Ds_MerchantParameters' parameter in all versions up to, and including, 1.0.12 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

A WordPress payment plugin, Pago por Redsys, can reflect attacker-supplied script back to a user through the Ds_MerchantParameters parameter. An attacker would need to trick someone into clicking a crafted link. Impact is usually session, account, or page-context theft or manipulation, not direct server takeover.

Executive priority

Schedule remediation promptly for affected WordPress commerce sites, especially customer-facing payment flows. This is not described as actively exploited, but reflected XSS can support credential theft, payment-flow abuse, and brand-impacting phishing.

Technical view

CVE-2024-12467 is a reflected XSS issue in Pago por Redsys versions up to and including 1.0.12. The source attributes it to insufficient sanitization and output escaping of Ds_MerchantParameters. CVSS 3.1 is 6.1, network exploitable, unauthenticated, low complexity, with required user interaction and changed scope.

Likely exposure

Exposure is limited to WordPress sites running the grafreak Pago por Redsys plugin at version 1.0.12 or earlier. Sites not using this plugin are not indicated as affected by the provided sources.

Exploitation context

The bundle says exploitation requires user interaction, such as clicking a link. KEV is false, and no provided source states active exploitation. Treat this as phishing-assisted web risk rather than confirmed in-the-wild compromise.

Researcher notes

Evidence points to reflected XSS tied to Ds_MerchantParameters and corrected code references in the 1.0.13 WordPress plugin tree. The provided bundle does not include exploit telemetry, a KEV listing, or broader product impact beyond this plugin.

Mitigation direction

  • Update Pago por Redsys beyond 1.0.12 after checking vendor or WordPress plugin guidance.
  • If immediate update is not possible, disable the plugin until remediated.
  • Prioritize sites where the plugin handles customer payment redirects or logged-in user flows.
  • Monitor vendor, Wordfence, and WordPress plugin sources for current fixed-version guidance.

Validation and detection

  • Inventory WordPress installations for the Pago por Redsys plugin and installed version.
  • Confirm whether any instance is running version 1.0.12 or earlier.
  • Review payment and callback pages for reflected Ds_MerchantParameters handling.
  • Check web logs for unusual requests containing Ds_MerchantParameters.
  • Verify remediation by confirming deployment of a non-affected plugin version.
