All in One Invite Codes Security & Risk Analysis

The 'all-in-one-invite-codes' v1.2.0 plugin presents a mixed security posture. While it demonstrates good practices in several areas, such as a high percentage of properly escaped output and no identified file operations or external HTTP requests, significant concerns remain. The presence of an unprotected AJAX handler is a critical finding, creating an accessible entry point that could be exploited without proper authentication. Although taint analysis found no unsanitized paths, the existence of an unprotected endpoint bypasses this protection. The plugin has a history of two medium severity vulnerabilities, both related to Cross-Site Scripting, with the last one occurring in July 2022. While these are currently patched, the recurring nature of XSS issues suggests a potential weakness in input sanitization in certain contexts. The plugin also uses bundled libraries, DataTables and Freemius v1.0, which if outdated, could introduce further risks, although their current version status is not detailed here. In conclusion, the plugin has strengths in output escaping and avoiding dangerous functions, but the unprotected AJAX handler and historical XSS vulnerabilities are serious points of concern that elevate the overall risk.
