Simple Image Sizes Security & Risk Analysis

The 'simple-image-sizes' plugin version 3.2.4 exhibits a generally good security posture, with strong adherence to best practices in several key areas. The plugin demonstrates excellent output escaping, with 91% of outputs properly sanitized, and a low proportion of SQL queries using prepared statements (67%). Furthermore, the absence of file operations, external HTTP requests, and dangerous functions is a positive indicator. Taint analysis shows no critical or high severity flows with unsanitized paths, suggesting a low risk of immediate code execution vulnerabilities.

However, a significant concern arises from the presence of one unprotected AJAX handler. This creates a direct entry point for unauthenticated attackers, potentially leading to the exploitation of any vulnerabilities within that specific handler. While the plugin has a history of one medium severity CVE related to Cross-site Scripting, which was last seen in 2025, the fact that it's not marked as unpatched is reassuring. The history indicates that vulnerabilities of this type have been addressed in the past. The strengths lie in code sanitization and the absence of common web application attack vectors, but the unprotected AJAX handler represents a critical weakness that requires immediate attention.
