CVE-2026-2718: Dealia <= 1.0.8 - Authenticated (Contributor+) Stored Cross-Site Scripting via Gutenberg Block Attributes

The Dealia – Request a Quote plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Gutenberg block attributes in all versions up to, and including, 1.0.8. This is due to the use of `wp_kses()` for output escaping within HTML attribute contexts where `esc_attr()` is required. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

CVE-2026-2718 affects the Dealia – Request a Quote WordPress plugin. Authenticated users with Contributor-level access or higher may store malicious scripts inside Gutenberg block attributes. Those scripts can run when someone views the affected page. This is mainly a website integrity and user-trust risk, not a server takeover issue based on current sources.

Executive priority

Address during the next normal WordPress security maintenance cycle, sooner for sites with many content contributors or weak account controls. This is not currently supported as actively exploited, but stored XSS can damage customer trust, affect administrators, and support account abuse if triggered in privileged sessions.

Technical view

The issue is stored cross-site scripting caused by using wp_kses() for output escaping in an HTML attribute context where esc_attr() is required. Sources state versions up to and including 1.0.8 are affected. The CVSS 3.1 score is 6.4, with low privileges required, network attack vector, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites running Dealia – Request a Quote, especially where Contributor or higher accounts are untrusted, shared, or compromised. Public visitors or administrators viewing injected pages may trigger the script. The provided affected metadata is inconsistent, so version validation should rely on vendor and Wordfence details.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires an authenticated WordPress account with Contributor-level privileges or higher. The business risk increases on sites with open registration, many content authors, weak account security, or externally managed content workflows.

Researcher notes

Public details point to improper escaping in Gutenberg block attribute output, specifically wp_kses() used where esc_attr() is needed. References include Wordfence and WordPress plugin Trac paths. No exploit code, proof of active exploitation, or definitive patch version is included in the provided sources. Affected-version metadata should be treated carefully due inconsistency.

Mitigation direction

  • Inventory WordPress sites for the Dealia – Request a Quote plugin.
  • Check vendor, WordPress plugin, and Wordfence guidance for a fixed version.
  • Update the plugin if a trusted fixed release is available.
  • Disable or remove the plugin if no safe version can be confirmed.
  • Restrict Contributor-level access to trusted users only.
  • Review recent content changes by Contributor-level users or higher.

Validation and detection

  • Confirm whether Dealia – Request a Quote is installed.
  • Record the installed plugin version on each WordPress site.
  • Treat versions up to and including 1.0.8 as potentially affected.
  • Review pages using Dealia Gutenberg blocks for suspicious attributes.
  • Check whether untrusted users have Contributor or higher roles.
  • Verify output escaping changes against vendor-published fixes when available.
