Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XXE: Insecure default configuration of XML reading APIs allows attackers to submit maliciously crafted XML payloads containing external DTD entities, risking local file disclosure or SSRF. This was mitigated by explicitly configuring XmlReader.Create to disable DTD processing and external entity resolution.
Auth Bypass: The authorizeUser function was susceptible to bypasses or null-reference exceptions when handling HTTP requests with a null ClaimsPrincipal identity. Safeguarding this entry point requires explicit validation of the user's identity object before evaluating authorization policies.
Cross-Site Scripting (XSS): Using unencoded rendering helper functions such as 'rawText' inside dynamic HTML views can let attackers inject executable scripts if untrusted user input is rendered directly. Safe alternatives like 'encodedText' must be used systematically.
