Security readout for executives and security teams
Plain-English summary
A WordPress newsletter plugin from Europe Ecologie Les Verts has a reflected XSS issue through version 4.8.2. An attacker would need a user to follow a crafted request, but successful abuse could run script in the victim’s browser and affect session data or page integrity.
Executive priority
Treat this as a high-priority WordPress plugin exposure where the plugin is installed. Prioritize public-facing sites, sites with authenticated user sessions, and sites handling sensitive visitor or campaign data.
Technical view
CVE-2025-23602 is CWE-79 improper input neutralization during web page generation in the WordPress EELV Newsletter plugin. The CVSS 3.1 score is 7.1 with network attack vector, low complexity, no privileges required, user interaction required, and changed scope.
Likely exposure
Exposure is limited to WordPress sites running the EELV Newsletter plugin at version 4.8.2 or earlier. The provided source metadata does not identify affected endpoints, exploit prerequisites beyond user interaction, or a fixed version.
Exploitation context
The source bundle does not show CISA KEV listing or other evidence of active exploitation. Risk remains meaningful because reflected XSS can be triggered remotely and requires no attacker authentication, but it depends on victim interaction.
Researcher notes
The provided data identifies reflected XSS and CVSS details but does not include vulnerable parameter names, proof-of-concept material, or a named patched version. The affected metadata is sparse, so rely on the description’s through-4.8.2 scope unless vendor guidance says otherwise.
Mitigation direction
- Inventory WordPress sites for the EELV Newsletter plugin.
- Remove or disable the plugin if it is unnecessary.
- If installed at version 4.8.2 or earlier, check vendor or Patchstack guidance.
- Apply any vendor-provided fixed release when confirmed.
- Use compensating controls to reduce untrusted reflected input exposure.
Validation and detection
- Confirm whether the eelv-newsletter plugin is installed on each WordPress site.
- Record installed plugin versions and flag version 4.8.2 or earlier.
- Review vendor, CVE, and Patchstack records for fixed-version guidance.
- Check access logs for unusual requests targeting plugin-controlled pages or parameters.
- Validate that removal, disablement, or update does not break newsletter workflows.

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.
