Security readout for executives and security teams
Plain-English summary
CVE-2025-23836 is a reflected cross-site scripting issue in the WordPress Custom Coming Soon plugin. A vulnerable site could cause a visitor or administrator to run attacker-controlled script after interacting with a crafted link. The sources do not show confirmed active exploitation.
Executive priority
Treat this as a high-priority web exposure issue for any WordPress site using the plugin. Urgency is highest where administrators or customers may follow external links to the site, but current evidence does not support claiming known active exploitation.
Technical view
The issue is CWE-79 improper neutralization during web page generation in SuryaBhan Custom Coming Soon, package custom-coming-soon, affecting versions through 2.2. CVSS 3.1 is 7.1, with network attack vector, low complexity, no privileges required, and required user interaction.
Likely exposure
Exposure is likely limited to WordPress sites that have the Custom Coming Soon plugin installed at version 2.2 or earlier. The CVE data does not provide CPEs and does not name other affected products.
Exploitation context
The CVSS vector indicates exploitation is remote and low complexity, but requires user interaction. The CVE is not listed as KEV in the provided bundle, and no cited source confirms active exploitation.
Researcher notes
Available evidence identifies reflected XSS and CVSS impact, but does not include a proof of concept, vulnerable parameter details, exploit telemetry, or a named fixed version in the supplied bundle. Avoid assuming exploitability beyond the CVSS and Patchstack/CVE descriptions.
Mitigation direction
- Inventory WordPress sites for the Custom Coming Soon plugin and version.
- Check Patchstack and vendor guidance for a fixed version or official mitigation.
- Update if a fixed release is available from trusted plugin sources.
- Disable or remove the plugin where no fixed guidance is available.
Validation and detection
- Confirm whether Custom Coming Soon is installed on each WordPress site.
- Verify installed versions and flag 2.2 or earlier as affected.
- Review Patchstack and CVE records for updated remediation details.
- After remediation, confirm the plugin is updated, disabled, or removed.

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.
