Serena before 2.0.0 Symlink Following in File Tools Allows Access Outside Project Root
CVSS Score
7.1
EPSS Score
0.0%
EPSS Percentile
0th
Serena before 2.0.0 contains an improper link resolution vulnerability that allows attackers to access files outside the project root by committing symlinks inside a repository. Project.is_path_in_project() normalizes paths lexically without resolving symlinks, so file tools like read_file and create_text_file can read or overwrite files such as SSH keys or cloud credentials.
