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.","published":"2026-10-13T14:17:36.060","modified":"2026-10-13T14:17:36.060","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/oraios/serena/commit/6f20f9b822d85bb063008e786f808d04619dd54e","label":"oraios/serena@6f20f9b"},"references":[{"type":"WEB","url":"https://github.com/oraios/serena"},{"type":"WEB","url":"https://github.com/oraios/serena/blob/v1.7.0/src/serena/project.py"},{"type":"WEB","url":"https://github.com/oraios/serena/commit/6f20f9b822d85bb063008e786f808d04619dd54e"},{"type":"WEB","url":"https://github.com/oraios/serena/issues/2144"},{"type":"WEB","url":"https://github.com/oraios/serena/releases/tag/v2.0.0"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/serena-before-2.0.0-symlink-following-in-file-tools-allows-access-outside-project-root"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-13T14:17:36.060"}}
