1) Information disclosure (CVE-ID: CVE-2018-1340)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to use of a cookie for client-side storage of the user's session token that can leak the "secure" flag. A remote attacker can eavesdrop on the network to intercept the user's session token if unencrypted HTTP requests are made to the same domain.
