Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

XML External Entity (XXE): User-supplied or configured XSLT stylesheets were processed without disabling external entities, exposing the server to XXE injections through the TransformerFactory.

Auth Bypass: Lack of null validation when authenticating unknown users triggers NullPointerExceptions inside compareCredentials, facilitating authentication bypass or service disruption.

Information Disclosure: NullPointerExceptions during credential comparison for non-existent users allowed attackers to enumerate valid usernames based on different response behaviors.
