Tickera – Sell Tickets & Manage Events Security & Risk Analysis

The Tickera Event Ticketing System plugin, version 3.5.6.8, exhibits a mixed security posture. On the positive side, it demonstrates strong practices in SQL query handling and output escaping, with 100% of SQL queries using prepared statements and all output being properly escaped. The plugin also incorporates a significant number of capability checks (81) and nonce checks (35), which are vital for secure WordPress development.

However, several areas raise concerns. The plugin has a substantial attack surface with 53 total entry points, and critically, 6 of these are unprotected AJAX handlers, presenting a significant risk of unauthorized actions. The taint analysis reveals 15 flows with unsanitized paths, 6 of which are flagged as high severity, indicating potential vulnerabilities that could be exploited if not properly handled. Furthermore, the plugin's vulnerability history is extensive, with 13 known CVEs, including 2 high severity and 11 medium severity vulnerabilities. While there are currently no unpatched CVEs, this history suggests a recurring pattern of security weaknesses.

In conclusion, while Tickera has implemented good practices in areas like SQL and output handling, the high number of unprotected AJAX handlers and the significant number of high-severity taint flows are serious concerns that require immediate attention. The plugin's past vulnerability record also warrants careful consideration, suggesting that ongoing vigilance and a commitment to addressing security flaws are essential.
