Security readout for executives and security teams
Plain-English summary
CVE-2023-46197 affects the WordPress Popup by Supsystic plugin through version 1.10.19. An unauthenticated visitor may be able to access subscriber email addresses because of a path traversal weakness. The main business risk is privacy exposure of marketing or subscriber contact data, not site takeover.
Executive priority
Prioritize remediation for public WordPress sites that collect subscriber emails. This is not a critical infrastructure compromise signal, but it can create reportable privacy and trust impact if contact lists were exposed.
Technical view
The issue is classified as CWE-22 relative path traversal in Popup by Supsystic. CVSS 3.1 is 5.3: network exploitable, low complexity, no privileges, no user interaction, unchanged scope, low confidentiality impact, and no integrity or availability impact documented.
Likely exposure
Exposure is limited to WordPress sites running Popup by Supsystic version 1.10.19 or earlier, especially sites using the plugin to collect or store subscriber email addresses.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation evidence. The vulnerability is unauthenticated and low complexity, so internet-facing WordPress sites should still treat it as actionable.
Researcher notes
Do not assume broader WordPress compromise from the cited record. The documented impact is subscriber email address disclosure through relative path traversal. The source bundle does not provide endpoint details, proof-of-concept status, or a specific fixed version.
Mitigation direction
- Inventory WordPress sites for Popup by Supsystic installations.
- Disable or remove the plugin if version 1.10.19 or earlier is present.
- Check vendor, WordPress, or Patchstack guidance for a fixed version before re-enabling.
- Review subscriber data exposure handling requirements with privacy stakeholders.
Validation and detection
- Confirm the installed Popup by Supsystic version on each WordPress site.
- Verify whether the site stored subscriber email addresses during the exposure window.
- Review web logs for suspicious traversal-style requests targeting the plugin.
- Document whether the plugin was removed, disabled, or updated.
