Greek Multi Tool – Greeklish Slugs, Permalinks & Transliteration Security & Risk Analysis

The "greek-multi-tool" plugin version 3.3.1 exhibits a mixed security posture. The static analysis reveals a positive adherence to several security best practices, including a substantial percentage of properly escaped outputs (86%) and a reasonable usage of prepared statements for SQL queries (60%). Furthermore, the plugin demonstrates a strong commitment to securing its entry points, with all 7 AJAX handlers protected by authorization checks and no unprotected REST API routes, shortcodes, or cron events. The absence of dangerous functions, file operations, and external HTTP requests is also a notable strength.

However, the plugin's vulnerability history presents a significant concern. With two known CVEs, including one high and one medium severity vulnerability, and a recent vulnerability reported in March 2025, it indicates a pattern of past security weaknesses. The common types of vulnerabilities, "Missing Authorization" and "Cross-site Scripting," suggest potential issues with how user input is handled and access controls are implemented. While there are currently no unpatched vulnerabilities, this history necessitates caution and suggests that while the developers are addressing issues, they have a propensity to introduce them. The static analysis itself found no critical or high severity taint flows, which is reassuring, but the historical data should not be overlooked.
