Security readout for executives and security teams
Plain-English summary
This is an authenticated stored cross-site scripting flaw in the Form Maker by 10Web WordPress plugin. A form title was not safely escaped before display in the admin editor, so malicious content saved there could run in an administrator’s browser. The sources do not provide CVSS scoring or evidence of active exploitation.
Executive priority
Treat as a timely WordPress plugin hygiene item, not an emergency based on current evidence. Prioritize sites with delegated form editing or many WordPress users, because successful abuse could affect administrator browsers and sessions.
Technical view
CVE-2021-24526 is CWE-79 in Form Maker by 10Web before 1.13.60. The vulnerable path involves Form Title output in an HTML attribute while editing a form in the WordPress admin dashboard. The issue requires authenticated access capable of modifying forms and results in stored XSS within the admin context.
Likely exposure
Exposure is likely limited to WordPress sites running Form Maker by 10Web versions before 1.13.60, especially where non-admin users can create or edit forms. Public internet exposure alone is not enough; authenticated plugin access matters.
Exploitation context
The supplied sources describe authenticated stored XSS but do not cite public exploitation, weaponization, or CISA KEV listing. Risk increases if lower-privileged users can edit forms or if administrator sessions process untrusted form titles.
Researcher notes
The source bundle gives the core bug class and affected version boundary but lacks CVSS metrics, detailed privilege requirements, and exploit-status detail. Validation should focus on plugin version, role permissions, and whether form titles are treated as trusted administrative content.
Mitigation direction
- Upgrade Form Maker by 10Web to version 1.13.60 or later.
- Check vendor and WPScan guidance for any newer fixed version.
- Restrict form creation and editing to trusted administrators.
- Review existing form titles for unexpected active content.
- Remove stale plugin copies from unused WordPress instances.
Validation and detection
- Inventory WordPress sites using Form Maker by 10Web.
- Confirm installed plugin versions are 1.13.60 or later.
- Identify accounts and roles allowed to edit forms.
- Review recent form-title changes in administrative logs, if available.
- Verify administrators are not using shared or unnecessary privileged accounts.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
