Symlink following vulnerability in Gleam’s Hex package export allows files outside the project root to be embedded in the generated package tarball.<\/p>\n
The file collection helpers (gleam_files, native_files, private_files) in compiler-cli\/src\/fs.rs use follow_links(true) when walking publishable directories such as src\/ and priv\/. The collected paths are added to the package archive via add_path_to_tar in compiler-cli\/src\/publish.rs without verifying that the resolved target remains within the project root. A symlink placed under a publishable directory will cause gleam export hex-tarball or gleam publish to embed the contents of the symlink target into the generated Hex package.<\/p>\n
An attacker with write access to the project repository can place a symlink in src\/ or priv\/ pointing to an arbitrary file. When a maintainer or CI pipeline runs gleam publish or gleam export hex-tarball, local files readable by the publisher (such as secrets, tokens, or SSH keys) are silently embedded into the published package artifact.<\/p>\n
