Last modified
CVE-2026-45225 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. Heym before 0.0.21 contains a path traversal vulnerability in the file upload endpoint that allows authenticated users to write attacker-controlled files to arbitrary locations by supplying a crafted filename with traversal sequences. Attackers can exploit the unvalidated filename parameter in the upload_file() handler to bypass path restrictions and write, read, or delete files outside the intended storage directory.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
