GHSA-86G4-8JPX-6PGQ

Vulnerability from github – Published: 2026-08-04 06:31 – Updated: 2026-08-04 06:31

Details

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.

Severity

8.7 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
