Vulnerability from github – Published: 2026-10-19 18:32 – Updated: 2026-10-19 18:32

Details

GDevelop desktop app through 5.6.284 contains a credential leak vulnerability that allows attackers to steal the gd_resource cookie by supplying attacker-controlled resource URLs in project files. Attackers can get victims to open a crafted project, causing downloadLocalFile() to send the cookie to their server and expose private cloud project resources.

Severity

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.
