An HTML injection vulnerability exists in the Google Chat webhook notification  sent by Thinkst Applied Research Canarytokens, enabling Interface Manipulation in Google Chat. An attacker can insert limited HTML content including links.

This issue affects Canarytokens: from Docker tag sha-4aef1db90 before sha-8ab4dccd, from Git commit 4aef1db90 before 8ab4dccd.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
