A code injection vulnerability exists in the LINE Android app prior to version 26.7.2.

The profile rendering component does not adequately validate or sandbox externally supplied script content embedded in profile templates.

As a result, an attacker who is able to place crafted content in a profile could cause unintended code to execute with the application's privileges when a victim views that profile.

A server-side mitigation has been deployed that also protects existing Android clients that have not been updated to version 26.7.2.
