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.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","cwes":["CWE-59"],"vendors":[],"products":[],"references":[{"url":"https://github.com/oraios/serena","tags":[]},{"url":"https://github.com/oraios/serena/blob/v1.7.0/src/serena/project.py","tags":[]},{"url":"https://github.com/oraios/serena/commit/6f20f9b822d85bb063008e786f808d04619dd54e","tags":[]},{"url":"https://github.com/oraios/serena/issues/2144","tags":[]},{"url":"https://github.com/oraios/serena/releases/tag/v2.0.0","tags":[]},{"url":"https://www.vulncheck.com/advisories/serena-before-2.0.0-symlink-following-in-file-tools-allows-access-outside-project-root","tags":[]},{"url":"https://github.com/oraios/serena/issues/2144","tags":[]}],"exploitRefs":[{"url":"https://github.com/oraios/serena","tags":[]},{"url":"https://github.com/oraios/serena/blob/v1.7.0/src/serena/project.py","tags":[]},{"url":"https://github.com/oraios/serena/commit/6f20f9b822d85bb063008e786f808d04619dd54e","tags":[]},{"url":"https://github.com/oraios/serena/issues/2144","tags":[]},{"url":"https://github.com/oraios/serena/releases/tag/v2.0.0","tags":[]},{"url":"https://github.com/oraios/serena/issues/2144","tags":[]}],"hasPoc":true,"ai":null}
