SlimStat Analytics Security & Risk Analysis
wordpress.org/plugins/wp-slimstatThe leading web analytics plugin for WordPress
Is SlimStat Analytics Safe to Use in 2026?
Generally Safe
Score 88/100SlimStat Analytics has a strong security track record. Known vulnerabilities have been patched promptly. It's a solid choice for most WordPress installations.
WP-Slimstat v5.4.3 presents a mixed security posture. On the positive side, the plugin demonstrates good practices in its handling of SQL queries, with 97% utilizing prepared statements, and a strong emphasis on output escaping, with 83% of outputs properly escaped. The presence of 25 nonce checks and 28 capability checks also indicates an awareness of common security controls.
However, significant concerns arise from the static analysis. A substantial attack surface is exposed, with 7 out of 19 entry points lacking authentication checks, including AJAX handlers and REST API routes. The taint analysis reveals 14 flows with unsanitized paths, with 7 flagged as high severity, indicating potential for malicious input to be processed without adequate validation. The use of dangerous functions like `assert`, `unserialize`, `shell_exec`, and `proc_open` further amplifies the risk, especially when combined with unsanitized input.
The plugin's vulnerability history is also a major red flag, with 23 known CVEs, all of which are surprisingly marked as patched, though the recency of the last vulnerability in 2026 (likely a typo, but noted) doesn't provide current reassurance. The historical focus on SQL Injection, Missing Authorization, CSRF, and XSS, coupled with the current taint analysis findings, suggests recurring weaknesses in input validation and authorization mechanisms. While the current version may not have unpatched CVEs, the underlying patterns of vulnerabilities and the identified static analysis issues paint a picture of a plugin that requires vigilant monitoring and potential code review to ensure long-term security.
