TelSender – Сontact form 7, Events, Wpforms, ninja forms and woocommerce to telegram bot Security & Risk Analysis

The 'telsender' plugin, version 1.14.15, exhibits a mixed security posture. On the positive side, it demonstrates good practices by utilizing prepared statements for all SQL queries and a high percentage of properly escaped output. The limited attack surface with only two entry points, both appearing to be protected by authorization checks, is also a strength. However, the presence of the `unserialize` function is a significant concern, as it can lead to remote code execution if used with untrusted input. Although the taint analysis did not reveal critical or high severity flows in this specific scan, the potential for exploiting `unserialize` remains high, especially if inputs are not strictly validated before being passed to it. The vulnerability history shows a concerning pattern of past issues, including a high-severity vulnerability related to missing authorization and cross-site scripting. The presence of a "high" severity vulnerability in the past, coupled with the potential risk of `unserialize`, suggests a history of security oversights that could resurface if not meticulously addressed. While the plugin currently has no unpatched CVEs, its past record warrants vigilance.
