Description
Description
envd provides reproducible development environments for humans and agents. In versions starting with 0.3.38 and before 1.3.6, insufficient containment of host-side requirements-file reads in install.python_packages(requirements=...) could allow access to files outside the build context. An attacker able to influence build input could cause file contents interpreted as dependency entries to appear in debug logs or build-step metadata, subject to the envd process’s permissions. Exploitation in version 1.3.5 additionally requires concurrent modification of relevant filesystem paths. This issue is fixed in version 1.3.6.

| CWE ID | Description |
|---|---|
| CWE-22 | The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |
| CWE-367 | The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. |
