Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

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

Reaching this weakness in LightStart < 2.0.7 takes any authenticated account. 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 LightStart the fix is 2.0.7: builds < 2.0.7 are affected, anything from 2.0.7 onward is not.

Remediation

Update to version 2.0.7, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: LightStart 2.0.7 closes this, and updating the plugin is the step that ends it.
