CVE-2024-45489

CVSS Score

9.8 / 10

Product(s) Impacted

Arc

  • before 2024-08-26

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's ID. This installs the boost in the victim'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.

Weaknesses

CWE-284
Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
