Security readout for executives and security teams
Plain-English summary
CVE-2026-27361 is a high-severity access control flaw in the WordPress Responsive Posts Carousel Pro plugin up to version 15.1. A remote, unauthenticated attacker may access confidential information because authorization checks are missing or misconfigured. Public sources do not state active exploitation or a fixed version.
Executive priority
Treat as high priority for WordPress environments using this plugin, especially sites containing private content. The main business risk is unauthorized disclosure. Because no fix is named in the provided sources, prioritize inventory, risk-based containment, and vendor guidance tracking.
Technical view
The CVE describes CWE-862 Missing Authorization in WebCodingPlace Responsive Posts Carousel Pro, package responsive-posts-carousel-pro, affecting versions through 15.1. CVSS 3.1 is 7.5: network exploitable, low complexity, no privileges, no user interaction, with high confidentiality impact and no stated integrity or availability impact.
Likely exposure
Exposure is likely limited to WordPress sites running Responsive Posts Carousel Pro version 15.1 or earlier. Public data does not identify affected endpoints, default configurations, or a fixed release. Sites not using this plugin are not indicated as affected.
Exploitation context
The CVSS vector indicates remote unauthenticated exploitation with low complexity and no user interaction. The issue is not listed in CISA KEV in the provided bundle, and no cited source confirms active exploitation. Public sources do not provide exploit details.
Researcher notes
Evidence is limited to the CVE record and Patchstack entry. The record states missing authorization, but does not name affected functions, endpoints, proof-of-concept status, or remediation version. Avoid assuming exploitation until a cited source or KEV listing supports it.
Mitigation direction
- Inventory WordPress sites for Responsive Posts Carousel Pro installations.
- If installed, determine whether the version is 15.1 or earlier.
- Check WebCodingPlace, WordPress plugin, and Patchstack guidance for a fixed version or workaround.
- Restrict or disable the plugin if business risk outweighs current need.
- Prioritize review of sites handling sensitive or regulated content.
Validation and detection
- Confirm plugin presence and version from WordPress administration or asset inventory.
- Compare installed versions against the affected range through 15.1.
- Review plugin-related access to sensitive content for unexpected unauthenticated exposure.
- Monitor web logs for unusual requests to plugin functionality.
- Recheck public advisories for updated fix and exploitation information.
