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

Description

includes/core/is_user.php in NukeViet before 4.3.04 deserializes the untrusted nvloginhash cookie (i.e., the code relies on PHP's serialization format when JSON can be used to eliminate the risk).

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update nukeviet/nukeviet to 4.3.04 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-32wr-8wxm-852c is resolved across your whole dependency graph.

  3. Workarounds

    Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
