Security readout for executives and security teams

Plain-English summary

A WordPress site using SKT Blocks version 2.0 or older may allow stored cross-site scripting. An attacker with some authenticated access could place hostile content that runs when another user views affected pages or editor content. Business impact is usually moderate, but it matters on public sites and admin-heavy workflows.

Executive priority

Treat this as a routine but time-sensitive WordPress plugin issue. Prioritize public websites, sites with multiple content contributors, and sites where WordPress administrators commonly view user-created content.

Technical view

CVE-2025-46235 is a CWE-79 stored XSS issue in sonalsinha21 SKT Blocks, package skt-blocks, through version 2.0. CVSS 3.1 is 6.5: network reachable, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to WordPress installations with the SKT Blocks Gutenberg page builder plugin installed at version 2.0 or older. The bundle does not identify affected themes, other SKT products, or non-WordPress software.

Exploitation context

The CVE is not listed as KEV in the provided bundle, and no cited source confirms active exploitation. The vulnerability requires a low-privileged actor and a victim interaction path, consistent with stored XSS in editable WordPress content.

Researcher notes

The source bundle does not name the vulnerable block, parameter, sanitization failure, fixed version, or exploit availability. Do not extrapolate to other SKT plugins. Validation should focus on installed plugin version, contributor access paths, and whether vendor guidance now names a patched release.

Mitigation direction

  • Inventory WordPress sites for the skt-blocks plugin.
  • Check vendor and Patchstack guidance for an official fixed version.
  • Update the plugin if a fixed release is available.
  • Disable or remove the plugin where no supported fix is available.
  • Limit content-editing privileges to trusted users only.

Validation and detection

  • Confirm whether skt-blocks is installed and version is 2.0 or older.
  • Review who can create or edit SKT Blocks content.
  • Check site content and revisions for unexpected script-like markup.
  • Verify remediation by confirming the plugin is updated, disabled, or removed.
  • Monitor vendor, CVE, and Patchstack records for fix status changes.
