What an attacker can do

An attacker can bypass justification verification by submitting a valid message with a correct justification and then reusing the same cached justification in contexts where it would normally be invalid. Vendor/CNA’s CVSS 3.1 assessment (base score 5.9/10) rates confidentiality impact as none; integrity impact as high; availability impact as low. NVD’s CVSS 3.1 assessment (base score 6.5/10) rates confidentiality impact as none; integrity impact as high; availability impact as low.
