Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WPMU DEV - Your All-in-One WordPress Platform Forminator forminator.This issue affects Forminator: from n/a through <= 1.29.0.
Security readout for executives and security teams
Plain-English summary
CVE-2024-29777 is a reflected cross-site scripting issue in the WordPress Forminator plugin through version 1.29.0. A successful attack requires user interaction, but could let an attacker run script in a victim's browser, affecting confidentiality, integrity, and availability at limited levels.
Executive priority
Treat this as a high-severity WordPress plugin exposure. Prioritize public sites and any site where administrators or customers interact with Forminator-generated pages, but do not claim emergency exploitation without new evidence.
Technical view
The CVE describes CWE-79 improper input neutralization during web page generation in Forminator. CVSS 3.1 is 7.1: network exploitable, low complexity, no privileges required, user interaction required, and changed scope. The source bundle does not provide payload details or a fixed version.
Likely exposure
Internet-facing WordPress sites using the Forminator plugin package `forminator` at version 1.29.0 or earlier are the relevant exposure. Sites without the plugin, or on unaffected versions, are not indicated as affected by the provided sources.
Exploitation context
The provided data does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability is reflected XSS, so practical abuse normally depends on convincing a victim to interact with attacker-controlled content or a crafted link.
Researcher notes
Evidence is limited to CVE and Patchstack metadata. The affected range, CWE, and CVSS vector are clear, but the bundle does not include technical root cause, vulnerable parameter, exploit status, or fixed release details.
Mitigation direction
Inventory WordPress sites for the Forminator plugin and record installed versions.
Prioritize sites running Forminator 1.29.0 or earlier for remediation.
Check WPMU DEV or Patchstack guidance for the fixed version before updating.
Disable or remove the plugin where business use is not required.
Apply compensating controls for high-risk sites until vendor remediation is confirmed.
Validation and detection
Confirm whether `forminator` is installed on each WordPress site.
Compare installed plugin versions against the affected range: through 1.29.0.
Verify remediation using vendor or Patchstack release guidance.
Review web and security logs for suspicious XSS-related requests.
Confirm no vulnerable Forminator version remains on internet-facing assets.

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.
