CVE-2026-121448 Details
Description
Dockhand before 1.0.54 contains a path traversal vulnerability that allows authenticated users to read, overwrite, and delete .env files outside the stacks root by double-encoding the stack name. Attackers can send %252e%252e sequences to /api/stacks/[name]/env/raw to disclose cross-environment secrets, write into protected directories, or poison deployment variables.
A path traversal vulnerability has been identified in Dockhand versions prior to 1.0.54. This vulnerability allows authenticated users to read, overwrite, and delete .env files located outside the designated stack root. The issue arises from a double-encoding of the stack name, which can be exploited by sending specific encoded sequences to the environment API endpoints. As a result, attackers can access cross-environment secrets, manipulate protected directories, or disrupt deployment variables.
Users are advised to update Dockhand to version 1.0.54 or later, where this vulnerability has been patched.
