CVE-2018-5131 Information

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.
