CyberRota Analysis
AI-GeneratedVersions of Hugo from v0.123.0 to v0.165.0 are vulnerable to a path traversal issue that allows attackers to exploit symlinks in parent directories during direct resource lookups, potentially disclosing sensitive files outside the intended project boundaries. This vulnerability primarily impacts developers using Hugo for static site generation who may inadvertently include malicious symlinks in their themes. Users of affected versions should prioritize upgrading to v0.165.0 or later to mitigate the risk.

Original NVD Description
Hugo is a static site generator. In versions after v0.123.0 and before v0.165.0, symlinks in parent directories were not dropped during direct resource lookups, allowing path confinement to be bypassed. An attacker who can place — or who convinces a site author to place — a symlink inside a mounted directory (for example, in a locally vendored theme under themes/) can cause functions that perform direct lookups, such as resources.Get and os.ReadFile, to follow that symlink and read files outside the intended project boundaries, disclosing their contents in the built site. Themes mounted as Go modules fetched from GitHub have symlinks stripped on download and are not affected, and multi-directory walks (e.g. content/asset walking) are not affected. This issue is an incomplete-fix follow-up to GHSA-c3wq-j5vh-68rc and GHSA-fw87-fv5r-9fpw; it is fixed in v0.165.0.
