Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Ataur R GutenKit gutenkit-blocks-addon allows Stored XSS.This issue affects GutenKit: from n/a through <= 2.2.2.
Security readout for executives and security teams
Plain-English summary
CVE-2025-46253 is a stored cross-site scripting issue in the WordPress GutenKit plugin, affecting versions up to 2.2.2. An authenticated user could save malicious content that later runs in another user’s browser when viewed. This is most concerning for sites allowing contributor-style access or multi-user editing.
Executive priority
Treat as a timely WordPress plugin hygiene issue, not an emergency unless the site allows untrusted content authors. Prioritize public-facing, multi-user, and business-critical WordPress sites using GutenKit.
Technical view
The CVE describes CWE-79 improper input neutralization during web page generation in Ataur R GutenKit gutenkit-blocks-addon. CVSS 3.1 is 6.5 with network attack vector, low complexity, low privileges required, user interaction required, and changed scope. The record identifies stored XSS affecting GutenKit through version 2.2.2.
Likely exposure
Exposure is limited to WordPress sites with the GutenKit plugin installed at version 2.2.2 or earlier. Risk increases where untrusted or lower-privileged users can create or edit content using the plugin.
Exploitation context
The source data does not report active exploitation, and CISA KEV status is false. Successful exploitation requires low privileges and user interaction, meaning an attacker likely needs an account or content-editing path and a victim to view affected content.
Researcher notes
Evidence is limited to the CVE record and Patchstack database entry. The provided sources do not include payload details, a confirmed fixed version, or exploitation in the wild. Validate against live vendor guidance before concluding remediation status.
Mitigation direction
Inventory WordPress sites for the GutenKit gutenkit-blocks-addon plugin.
Identify installations running GutenKit version 2.2.2 or earlier.
Check vendor and Patchstack guidance for fixed versions or official remediation.
Restrict content creation to trusted users until remediation is confirmed.
Review plugin usage where contributors, authors, or customers can submit content.
Validation and detection
Confirm the installed GutenKit plugin version from WordPress administration or asset inventory.
Verify whether the site allows low-privileged users to edit GutenKit content.
Check Patchstack and CVE records for updated affected-version or fix information.
Review security logs for unusual content edits by low-privileged accounts.
Confirm remediation by documenting upgrade, removal, or vendor-approved mitigation.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
