Which packages are affected by CVE-2024-56512?

CVE-2024-56512 affects the following packages: org.apache.nifi:nifi-web-api (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-56512?

Update org.apache.nifi:nifi-web-api to 2.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-56512 is resolved across your whole dependency graph.

How do I detect CVE-2024-56512 in my Maven dependencies?

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

How do I mitigate CVE-2024-56512 if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against CVE-2024-56512?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-56512 can be triaged on real exposure rather than presence alone.

Is CVE-2024-56512 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2024-56512, including . All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-56512?

CVE-2024-56512 has an EPSS (Exploit Prediction Scoring System) score of 3.1%, placing it in the 87th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-56512?

CVE-2024-56512 is classified as CWE-638 (CWE-638), CWE-862 (CWE-862). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Is there exploit tooling available for CVE-2024-56512?

A Nuclei detection template exists for CVE-2024-56512, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2024-56512 published, and has it been updated?

CVE-2024-56512 was published on December 28, 2024 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-World Exposure

1 pkg affected

☕org.apache.nifi:nifi-web-api

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

Creating a new Process Group can include binding to a Parameter Context, but in cases where the Process Group did not reference any Parameter values, the framework did not check user authorization for the bound Parameter Context. Missing authorization for a bound Parameter Context enabled clients to download non-sensitive Parameter values after creating the Process Group.

Creating a new Process Group can also include referencing existing Controller Services or Parameter Providers. The framework did not check user authorization for referenced Controller Services or Parameter Providers, enabling clients to create Process Groups and use these components that were otherwise unauthorized.

This vulnerability is limited in scope to authenticated users authorized to create Process Groups. The scope is further limited to deployments with component-based authorization policies. Upgrading to Apache NiFi 2.1.0 is the recommended mitigation, which includes authorization checking for Parameter and Controller Service references on Process Group creation.

How to detect CVE-2024-56512

A community-maintained Nuclei template exists for this CVE. You can scan for it directly:

nuclei -id cve-2024-56512 -u https://target

Template: Apache NiFi - Information Disclosure
Severity: medium
Impact: Attackers can create Process Groups bound to Parameter Contexts without proper authorization checks, enabling them to download non-sensitive parameter values and potentially access sensitive configuration data.
Remediation: Update Apache NiFi to version 2.1.0 or later to address the missing authorization checks for Parameter Contexts.
