CVE-2023-25304

Arbitrary code execution via unchecked pack paths

Published Mar 6, 2023 · Updated Nov 27, 2024

Path traversal in Prism Launcher before 6.2 allows attackers to write files outside an instance through import of a crafted .mrpack. The manual Modrinth-pack importer trusted each manifest path when constructing download targets instead of verifying that the resolved path stayed under the root .minecraft directory. A user must import the malicious local pack; successful exploitation can silently replace scripts or configuration files at arbitrary locations and lead to code execution.
