CVE-2025-61728 is a denial-of-service vulnerability in the Go standard library's archive/zip package. The flaw is caused by a super-linear file name indexing algorithm that is triggered the first time a file within a ZIP archive is opened. A maliciously constructed ZIP archive with a specific arrangement of file names can force the package to perform excessive work while building the archive index, resulting in disproportionate CPU consumption and, in reported cases, elevated memory usage. Applications written in Go that process attacker-supplied ZIP archives through archive/zip may become unresponsive or crash during archive handling.
