hugo: Hugo is a static site generator
CVE-2026-58403 is fixed in hugo on 1 platform by DEBIAN-CVE-2026-58403 (version 0.165.0-1), released July 6, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile "somefile" where somefile was a symlink pointing outside the mount would return the target's contents. This effectively let a symlink planted inside a theme or local mount read arbitrary files reachable to the user running hugo. This issue is fixed in v0.163.1.
