Security readout for executives and security teams
Plain-English summary
CVE-2026-1164 is a stored cross-site scripting issue in the Easy Voice Mail WordPress plugin through version 1.2.5. Malicious script could be saved through the voicemail message field and run when someone views the affected page. Public sources conflict on whether exploitation requires no login or Administrator access, so treat exposure carefully until vendor guidance is confirmed.
Executive priority
Address during the next WordPress maintenance window, sooner for internet-facing sites using this plugin. The risk is moderate because exploitation impact is browser-based, but source inconsistency around authentication means teams should not dismiss it without validation.
Technical view
The issue is CWE-79 caused by insufficient sanitization of the ‘message’ parameter and insufficient output escaping. CVSS 3.1 is 6.1 with PR:N and UI:R, but the description also says Administrator-level access is required. WordPress Trac references show vulnerable code locations and a later changeset, but the provided data does not clearly name a fixed release.
Likely exposure
WordPress sites using Easy Voice Mail version 1.2.5 or earlier may be exposed. Exposure is higher where the plugin is enabled on public-facing sites. The privilege requirement is unclear in the sources, with conflicting unauthenticated and Administrator-level claims.
Exploitation context
No CISA KEV listing is provided, and the source bundle does not cite active exploitation. Successful impact requires a user to view a page containing the stored script. Potential outcomes include limited data exposure or unauthorized actions in the victim’s browser context.
Researcher notes
Key uncertainty: the title and CVSS indicate unauthenticated exploitation, while the description states Administrator-level access. Do not assume either model without confirming upstream advisory details. The referenced Trac changeset may indicate remediation, but the provided data does not clearly identify the patched version.
Mitigation direction
- Inventory WordPress sites for the Easy Voice Mail plugin and version.
- Prioritize sites running Easy Voice Mail 1.2.5 or earlier.
- Review the WordPress plugin repository and vendor guidance for a fixed version.
- Update the plugin if a patched release is available.
- Disable the plugin if it is unnecessary or no safe version is available.
- Restrict administrative access and review who can submit voicemail messages.
Validation and detection
- Confirm whether Easy Voice Mail is installed and active.
- Record the installed plugin version from WordPress administration or asset inventory.
- Review plugin pages handling voicemail messages for unexpected stored content.
- Check WordPress logs for suspicious voicemail message submissions.
- Verify whether changes from WordPress Trac changeset 3467995 are present.
- Monitor vendor and Wordfence advisories for clarification on privilege requirements.

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.
