{"id":"CVE-2020-26284","aliases":["GHSA-8j34-9876-pvfq"],"url":"https://o3.security/vulnerability/CVE-2020-26284","summary":"Hugo can execute a binary from the current directory on Windows","details":"Hugo is a fast and Flexible Static Site Generator built in Go. Hugo depends on Go's `os/exec` for certain features, e.g. for rendering of Pandoc documents if these binaries are found in the system `%PATH%` on Windows. In Hugo before version 0.79.1, if a malicious file with the same name (`exe` or `bat`) is found in the current working directory at the time of running `hugo`, the malicious command will be invoked instead of the system one. Windows users who run `hugo` inside untrusted Hugo sites are affected. Users should upgrade to Hugo v0.79.1. Other than avoiding untrusted Hugo sites, there is no workaround.","published":"2020-12-21T23:15:12.157Z","modified":"2026-07-09T01:30:03.268106Z","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/gohugoio/hugo","fixedVersion":"0.79.1"}],"fix":null,"references":[{"type":"FIX","url":"https://github.com/gohugoio/hugo/security/advisories/GHSA-8j34-9876-pvfq"},{"type":"FIX","url":"https://github.com/golang/go/issues/38736"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T01:30:03.268106Z"}}
