Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

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, plugin.NewIdentityWithoutData, or 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 protocol.

An equivalent issue was fixed by the rage project, see advisory GHSA-4fg7-vxc8-qx5w.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for filippo.io/age, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update filippo.io/age to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-32gq-x56h-299c is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-32gq-x56h-299c can be triaged on real exposure rather than presence alone.

Tailored to GHSA-32gq-x56h-299c. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
