Security readout for executives and security teams
Plain-English summary
CVE-2026-25465 is a stored cross-site scripting issue in the WordPress CP Multi View Event Calendar plugin. An authenticated attacker may be able to save malicious input that later executes in another user’s browser. This can affect confidentiality, integrity, and availability at a limited level.
Executive priority
Treat this as a moderate-priority WordPress plugin risk. It is not reported as actively exploited, but stored XSS can support account abuse, content tampering, or session-impacting attacks if exposed to untrusted contributors.
Technical view
The issue is CWE-79 improper neutralization during web page generation in codepeople CP Multi View Event Calendar, package cp-multi-view-calendar. The CVSS 3.1 score is 6.5 with AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. Sources list versions through <= 1.4.36 as affected.
Likely exposure
Exposure is likely limited to WordPress sites with CP Multi View Event Calendar installed at an affected version. The CVSS vector indicates the attacker needs low privileges and a user must interact with or view affected content.
Exploitation context
No source in the bundle reports active exploitation, and CISA KEV status is false. The vulnerability is stored XSS, so risk increases where untrusted authenticated users can create or edit calendar-related content that others later view.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The CVE title references <= 1.4.36, while the Patchstack URL slug mentions 1.4.34; use the CVE affected range unless vendor guidance clarifies otherwise.
Mitigation direction
- Inventory WordPress sites for the cp-multi-view-calendar plugin and installed version.
- Check vendor, WordPress plugin, or Patchstack guidance for a fixed release or mitigation.
- Update the plugin if a vendor-supported fixed version is available.
- Restrict plugin content-editing permissions to trusted users until remediated.
- Monitor for unexpected script content in calendar entries or plugin-managed fields.
Validation and detection
- Confirm whether CP Multi View Event Calendar is installed on each WordPress site.
- Record the installed plugin version and compare it with <= 1.4.36.
- Review plugin changelogs or vendor advisories for a fixed version.
- Inspect calendar content for suspicious embedded script-like input.
- Verify remediation by confirming the site no longer runs an affected version.
