Security readout for executives and security teams
Plain-English summary
CVE-2026-27045 is a high-severity vulnerability in the WordPress WooCommerce Infinite Scroll plugin by sbthemes, affecting versions through 1.6.2. It involves unsafe handling of serialized data, which can let an authenticated attacker manipulate server-side objects. The listed impact is high for confidentiality, integrity, and availability.
Executive priority
Prioritize assessment for ecommerce WordPress sites because the stated impact includes full confidentiality, integrity, and availability compromise. Treat as high urgency where the plugin is present and user accounts are broadly available, but note that public sources do not confirm active exploitation.
Technical view
The issue is CWE-502: deserialization of untrusted data leading to PHP object injection in package sb-woocommerce-infinite-scroll. CVSS 3.1 is 8.8 with network access, low attack complexity, low privileges required, and no user interaction. Public sources do not provide exploit details, affected code paths, or a named fixed version.
Likely exposure
Exposure is likely limited to WordPress sites running WooCommerce Infinite Scroll through version 1.6.2. The CVSS vector indicates exploitation requires a low-privileged account, so public registration, customer accounts, or compromised WordPress users may increase risk.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability class can be serious in WordPress/PHP environments, but available sources do not document exploitation in the wild or provide proof-of-concept status.
Researcher notes
Evidence is limited to the CVE record and Patchstack database entry. The affected range is described as through 1.6.2, but the provided structured affected version data is sparse. No patch version, exploit chain, gadget requirement, or endpoint details are available in the provided sources.
Mitigation direction
- Inventory WordPress sites for the WooCommerce Infinite Scroll plugin.
- Identify plugin versions and flag installations at or below 1.6.2.
- Check vendor, WordPress plugin, or Patchstack guidance for an update or mitigation.
- If not business-critical, disable or remove the plugin pending vendor guidance.
- Restrict unnecessary low-privileged WordPress account creation where feasible.
Validation and detection
- Confirm whether sb-woocommerce-infinite-scroll is installed on each WordPress site.
- Record installed version and compare against affected versions through 1.6.2.
- Review WordPress account registration and low-privilege user exposure.
- Monitor vendor and Patchstack pages for fixed-version information.
- Check security logs for suspicious authenticated activity against affected sites.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
