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

Impact

The cloudstore.file.upload action in server/actions/action_cloudstore_file_upload.go writes user-supplied filenames directly to disk without proper validation.

This allows unauthenticated attackers to perform path traversal and zip slip attacks, leading to arbitrary file write and potential remote code execution.

CVSS Score: 10.0 Critical CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H CWE: CWE-22 (Path Traversal)

Patches

Upgrade to a patched version once released. The vulnerability affects all versions <= v0.11.3 (latest).

Workarounds

Restrict access to the cloudstore.file.upload action through authentication and authorization controls until a patch is available.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/daptin/daptin. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/daptin/daptin to 0.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9cp7-j3f8-p5jx 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 pinpoints whether GHSA-9cp7-j3f8-p5jx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-9cp7-j3f8-p5jx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
