Security readout for executives and security teams
Plain-English summary
CVE-2025-22815 is a stored cross-site scripting issue in the WordPress Button Block plugin. A logged-in user with some level of access may be able to save unsafe content that later runs in another user’s browser. This can affect confidentiality, integrity, and availability at a limited level.
Executive priority
Treat as a moderate web application risk. Prioritize affected public WordPress sites, especially those with multiple content editors or contributor workflows. Remediation should be scheduled promptly, but the bundle does not support emergency response for active exploitation.
Technical view
The issue is CWE-79 in bPlugins Button Block through version 1.1.9. CVSS 3.1 is 6.5: network attack vector, low complexity, low privileges required, user interaction required, and changed scope with low C/I/A impact. Sources do not provide exploit details or a confirmed fixed version.
Likely exposure
Exposure is limited to WordPress sites using the Button Block plugin at version 1.1.9 or earlier. Risk is higher where untrusted or less-trusted users can create or edit content that uses plugin blocks.
Exploitation context
The source bundle does not claim active exploitation, and KEV status is false. The CVSS vector indicates exploitation requires low privileges and user interaction, consistent with stored XSS in content viewed by another user.
Researcher notes
There is an evidence inconsistency: the title references plugin <=1.1.9, while the Patchstack URL text references 1.1.6. Use <=1.1.9 from the CVE description unless vendor guidance clarifies otherwise. No exploit code, fixed version, or mitigation detail is included in the supplied bundle.
Mitigation direction
- Inventory WordPress sites for the button-block plugin and installed versions.
- Check vendor, WordPress, CVE, or Patchstack guidance for a fixed safe version.
- Disable or remove the plugin where business impact is acceptable.
- Restrict content-editing privileges to trusted users until remediated.
- Review recent content changes involving Button Block blocks.
Validation and detection
- Confirm whether Button Block is installed on each WordPress instance.
- Flag any installed version at or below 1.1.9 as potentially affected.
- Review WordPress roles allowed to create or edit affected block content.
- Check recent posts and pages for unexpected script-like content or unauthorized changes.
- Monitor CVE and Patchstack records for corrected version information.

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.
