WP-Stats Security & Risk Analysis

The wp-stats plugin v2.56 presents a mixed security posture. While the static analysis reveals a relatively small attack surface with no unprotected entry points and a recent history of no currently unpatched vulnerabilities, several concerning patterns emerge from the code analysis. A significant concern is the complete lack of prepared statements for all 13 SQL queries, making it highly susceptible to SQL injection attacks. Furthermore, only 8% of output escaping is properly implemented, indicating a broad risk of Cross-Site Scripting (XSS) vulnerabilities across various output points. The presence of a past medium severity CSRF vulnerability, even if patched, suggests a historical tendency for security oversights in the plugin's development.

Despite the absence of critical taint flows and dangerous functions, the widespread use of raw SQL and inadequate output escaping, combined with a single past CSRF vulnerability, indicates a plugin that requires careful attention. The lack of capability checks on any of the identified entry points is also a notable weakness. While the plugin appears to have addressed its past vulnerabilities and has no known current issues, the fundamental coding practices regarding SQL and output sanitization leave it exposed to common web attack vectors. A user of this plugin should be aware of these underlying risks.
