All in One Time Clock Lite – Tracking Employee Time Has Never Been Easier Security & Risk Analysis

The "aio-time-clock-lite" v2.0.4 plugin presents a mixed security posture. While it demonstrates good practices by exclusively using prepared statements for SQL queries and performing a reasonable number of capability checks, significant concerns remain regarding its attack surface and vulnerability history. The presence of two AJAX handlers without authentication checks is a primary weakness, creating potential entry points for unauthorized actions. Taint analysis indicates unsanitized paths, which, although not flagged as critical or high severity in this scan, could potentially lead to vulnerabilities if exploited in conjunction with other weaknesses.

The plugin's vulnerability history, with 5 known medium-severity CVEs, including common types like Missing Authorization, Authorization Bypass, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF), is a significant red flag. The fact that all previously disclosed vulnerabilities are patched suggests a commitment to addressing security issues. However, the sheer number and variety of past vulnerabilities indicate a pattern of insecure coding practices that require ongoing vigilance. The most recent vulnerability was disclosed in late 2025, which is a concern for a plugin version that may be older.

In conclusion, the plugin has strengths in its SQL handling and some security checks. However, the unprotected AJAX endpoints, potential taint flow issues, and a history of multiple medium-severity vulnerabilities across various types necessitate careful consideration. Users should prioritize ensuring the plugin is up-to-date and be aware of the potential risks associated with the exposed AJAX endpoints, even if no critical issues were found in the current static analysis.
