What is CVE-2026-111448?
CVE-2026-111448 is a low-severity path traversal vulnerability in Wheels, published on 16 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Wheels 4.0.0 through 4.1.2 uses case-insensitive comparisons in path-containment checks on case-sensitive filesystems. Canonical-path checks for zip entries, package mappings, development assets/docs, guide images and image tags can accept paths through an existing symlink to a case-distinct sibling directory, allowing access outside the intended root, including limited file disclosure. Separately, the CLI database-dump output check can write outside the application root to an existing writable case-distinct sibling directory; that action requires the CLI POST, loopback and password gate. This is fixed in 4.2.0.
Weakness: CWE-178
