How to Fix GHSA-32gq-x56h-299c

To remediate this vulnerability, upgrade all affected Filippo.io/age dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

filippo.io/age fixed: 1.2.1 
Upgrade filippo.io/age to 1.2.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for filippo.io/age

How to Check if You Are Affected

To determine whether your application is affected by GHSA-32gq-x56h-299c, inspect your project dependencies for Filippo.io/age:

inspect dependencies for filippo.io/age

Analyze the terminal output to locate any version of Filippo.io/age in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-25: Path Traversal: '/../filedir', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "/../" sequences that can resolve to a location that is outside of that directory. In Filippo.io/age, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A plugin name containing a path separator may allow an attacker to execute an arbitrary binary. Such a plugin name can be provided to the age CLI through an attacker-controlled recipient or identity string, or to the [`plugin.NewIdentity`](https://pkg.go.dev/filippo.io/age/plugin#NewIdentity), [`plugin.NewIdentityWithoutData`](https://pkg.go.dev/filippo.io/age/plugin#NewIdentityWithoutData), or [`plugin.NewRecipient`](https://pkg.go.dev/filippo.io/age/plugin#NewRecipient) APIs. On UNIX systems, a directory matching `${TMPDIR:-/tmp}/age-plugin-*` needs to exist for the attack to succeed. The binary is executed with a single flag, either `--age-plugin=recipient-v1` or `--age-plugin=identity-v1`. The standard input includes the recipient or identity string, and the random file key (if encrypting) or the header of the file (if decrypting). The format is constrained by the [age-plugin](https://c2sp.org/age-plugin) protocol. An equivalent issue was fixed by the [rage](https://github.com/str4d/rage) project, see advisory [GHSA-4fg7-vxc8-qx5w](https://github.com/str4d/rage/security/advisories/GHSA-4fg7-vxc8-qx5w). Thanks to ⬡-49016 for reporting this.
