CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Smart Popup by Supsystic < 1.10.9 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Smart Popup by Supsystic the fix is 1.10.9: builds < 1.10.9 are affected, anything from 1.10.9 onward is not.

Remediation

Update to version 1.10.9, or a newer patched version
