Severity CVSS v4.0:

Pending analysis

Type:

CWE-284 Improper Access Control

Publication date:

Last modified:

Description

Arc before 2024-08-26 allows remote code execution in JavaScript boosts. Boosts that run JavaScript cannot be shared by default; however (because of misconfigured Firebase ACLs), it is possible to create or update a boost using another user&#39;s ID. This installs the boost in the victim&#39;s browser and runs arbitrary Javascript on that browser in a privileged context. NOTE: this is a no-action cloud vulnerability with zero affected users.
