From 7.2.0 until 9.0.0, ZipArchive::extract and ZipArchive::extract_unwrapped_root_dir use safe_prepare_path in src/read/zipfile.rs and simplified_components in src/path.rs to validate symbolic link targets with a lexical prefix comparison rather than resolving each intermediate link. An attacker who knows or can guess the absolute extraction destination can create a chain whose apparent target remains under the destination while an intermediate symlink resolves outside it, allowing attacker-controlled files to be created or overwritten with the extracting process's privileges. On Windows, discarded drive and UNC prefixes can permit a single-link escape when the process has SeCreateSymbolicLinkPrivilege, such as through administrator rights or Developer Mode. This regression is distinct from CVE-2025-29787. This issue is fixed in version 9.0.0.\n\n## Affected\n\n- `zip2 >= 7.2.0, < 9.0.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":40.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
