Description
CVE-2026-32685 is a path traversal vulnerability in Gleam versions from 1.16.0 up to but not including 1.17.0. It allows arbitrary file read and write outside the intended documentation output directory via insufficient validation of paths in the documentation.pages entries in gleam.toml. An attacker who can trick a user into building documentation on a malicious project or with malicious gleam.toml content can cause local files to be read and included in generated documentation or cause files to be written outside the expected output directory.
