Description

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

The vulnerability exists due to an error when handling cookies, as libsoup clients mistakenly allow cookies to be set for public suffix domains if the domain contains at least two components and includes an uppercase character. A remote attacker can set cookies for the domain they do not have access to and perform session fixation attacks.


Remediation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
