CVE-2018-5131
This vulnerability affects Firefox ESR < 52.7 and Firefox < 59.
MEDIUM 5.9EPSS 2.29%
Does this matter?
Lower severity and a low EPSS score (2.29%). Track it; it rarely justifies an emergency change on its own.
Description
Under certain circumstances the "fetch()" API can return transient local copies of resources that were sent with a "no-store" or "no-cache" cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing. This vulnerability affects Firefox ESR < 52.7 and Firefox < 59.
