CVE-2020-4640
An attacker can make use of this information to perform attacks by impersonating a user.
Does this matter?
Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.
Description
Certain IBM API Connect 10.0.0.0 through 10.0.1.0 and 2018.4.1.0 through 2018.4.1.13 configurations can result in sensitive information in the URL fragment identifiers. This information can be cached in the intermediate nodes like proxy servers, cdn, logging platforms, etc. An attacker can make use of this information to perform attacks by impersonating a user. IBM X-Force ID: 185510.
