Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XML External Entity (XXE): Insecure parsing of untrusted XML via DOMDocument can lead to local file disclosure or server-side request forgery (SSRF) if external entity resolution is not explicitly deactivated.
XML External Entity (XXE): Similar to its namespaced counterpart, legacy DOM query components are susceptible to XXE when invoking XML loading routines without disabling the libxml entity loader.
Auth Bypass: Lazy or delayed population of validated input data allows raw, unvalidated values to be fetched, bypassing intended validation schemas during data-binding operations.
