- Impact Highlight may record passwords on customer deployments when a password html input is switched to type="text" via a javascript "Show Password" button. This differs from the expected behavior which always obfuscates type="password" inputs. A customer may assume that switching to type="text" would also not record this input; hence, they would not add additional highlight-mask css-class obfuscation to this part of the DOM, resulting in unintentional recording of a password value when a Show Password button is used.

Recommended action: Upgrade to 6.0.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
