iPag Pagamentos Digitais Security & Risk Analysis

The ipag-woocommerce plugin v2.13.2 presents a significant security risk due to a large attack surface comprised entirely of unprotected AJAX handlers. With 3 AJAX entry points identified and none of them including authorization checks, any unauthenticated user could potentially trigger these actions, leading to a broad range of vulnerabilities. The taint analysis also revealed critical flows with unsanitized paths, which, despite not being classified as critical or high severity by the analysis, indicate a strong possibility of injection-type attacks if not properly handled. Furthermore, the plugin exhibits poor output escaping practices, with only 18% of outputs being properly escaped, increasing the risk of Cross-Site Scripting (XSS) vulnerabilities. The absence of known CVEs and a clean vulnerability history suggest that the plugin has not been publicly exploited or identified as vulnerable in the past, which is a positive sign. However, the current static analysis findings highlight fundamental security weaknesses that could be exploited even without prior known vulnerabilities.
