Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-15 Information Output Filtering good match

prevent

Directly mitigates reflected XSS by filtering information outputs to neutralize malicious scripts before web page generation.

SI-10 Information Input Validation good match

prevent

Prevents exploitation by validating and sanitizing untrusted inputs to block injection of malicious scripts into the WordPress plugin.

SI-2 Flaw Remediation good match

prevent

Addresses the specific flaw in Edwiser Bridge versions through <=3.0.8 by identifying, reporting, and applying timely remediation such as patching.
