vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Lifecycle Timeline
4DescriptionCVE.org
Starting from Rust 1.87.0 and before Rust 1.89.0, the tier 3 Cygwin target (x86_64-pc-cygwin) didn't correctly handle path separators, causing the standard library's Path API to ignore path components separated by backslashes. Due to this, programs compiled for Cygwin that validate paths could misbehave, potentially allowing path traversal attacks or malicious filesystem operations.
Rust 1.89.0 fixes the issue by handling both Win32 and Unix style paths in the standard library for the Cygwin target.
While we assess the severity of this vulnerability as "medium", please note that the tier 3 Cygwin compilation target is only available when building it from source: no pre-built binaries are distributed by the Rust project, and it cannot be installed through Rustup. Unless you manually compiled the x86_64-pc-cygwin target you are not affected by this vulnerability. Users of the tier 1 MinGW target (x86_64-pc-windows-gnu) are also explicitly not affected.

Technical ContextAI
Path traversal allows an attacker to access files outside the intended directory by manipulating file paths with sequences like '../'.
RemediationAI
Validate and sanitize file path inputs. Use a whitelist of allowed files or directories. Implement chroot jails or containerization.
