Security readout for executives and security teams
Plain-English summary
CVE-2026-27052 affects the WordPress Sales Countdown Timer for WooCommerce and WordPress plugin before version 1.1.9. A flaw in how PHP files are included can allow local file inclusion. For affected WordPress commerce sites, this could expose sensitive files or disrupt site integrity if an attacker has low-level access.
Executive priority
Treat as a high-priority WordPress plugin update for ecommerce sites. Prioritize internet-facing stores and sites with customer or subscriber accounts. There is no sourced evidence of active exploitation, but the potential business impact includes sensitive data exposure and site compromise.
Technical view
The issue is CWE-98: improper control of filenames used in PHP include/require statements. CVSS 3.1 is 7.5 high: network reachable, high complexity, low privileges required, no user interaction, and high confidentiality, integrity, and availability impact. Public sources identify affected versions as below 1.1.9.
Likely exposure
Exposure is likely limited to WordPress sites running the villatheme Sales Countdown Timer for WooCommerce and WordPress plugin below 1.1.9. The CVSS vector indicates an attacker needs low privileges, so sites allowing customer, subscriber, or other low-privilege accounts deserve priority review.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. Public details do not provide exploit mechanics. The risk is still meaningful because WordPress plugins are commonly internet-facing and the potential impact is high.
Researcher notes
Available public sources identify the vulnerable product, version range, CWE, and CVSS vector, but not vulnerable parameters, endpoints, or exploit details. Do not assume unauthenticated exploitation; CVSS indicates low privileges required. KEV is false in the provided data.
Mitigation direction
- Identify all WordPress sites using the affected plugin.
- Upgrade the plugin to version 1.1.9 or later if available.
- If upgrade is not possible, disable the plugin pending vendor guidance.
- Limit unnecessary low-privilege WordPress account creation.
- Monitor Patchstack, CVE, and vendor channels for updated guidance.
Validation and detection
- Check each site’s installed plugin version.
- Confirm no instance is running below 1.1.9.
- Review WordPress roles with access to plugin functionality.
- Check logs for unusual authenticated requests around plugin features.
- Document compensating controls where immediate update is delayed.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
