Real-World Exposure

1 pkg affected
☕org.nutz:nutzboot-parent

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

Description

A weakness has been identified in nutzam NutzBoot up to 2.6.0-SNAPSHOT. This affects the function getInputStream of the file nutzcloud/nutzcloud-literpc/src/main/java/org/nutz/boot/starter/literpc/impl/endpoint/http/HttpServletRpcEndpoint.java of the component LiteRpc-Serializer. Executing a manipulation can lead to deserialization. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is reported as difficult. The exploit has been made available to the public and could be used for attacks.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Remediation status

    The records we use list no patched version of org.nutz:nutzboot-parent for CVE-2025-13805. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    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.
