New CVE Detected

CVE-2026-41871 – Unauthenticated Reflection-Based Job Execution – Apache Nutch 1.10 through 1.22

Be the first to know when new zero-days emerge:

Summary

CVE-2026-41871 is a missing-authorization and unsafe-reflection vulnerability in Apache Nutch Server’s REST API that allows unauthenticated attackers to trigger reflection-based job execution using externally-controlled input. The flaw affects Apache Nutch versions 1.10 through 1.22 and carries a Critical CVSS v3.1 score of 9.8, reflecting its network-exploitable, no-authentication-required nature and potential for full compromise of confidentiality, integrity, and availability.

Technical details

  • Root cause: The Nutch Server REST API fails to enforce proper authorization on job-execution endpoints, and combines this with unsafe use of externally-controlled input to select classes/code (CWE-470, "Unsafe Reflection"), allowing arbitrary job classes to be instantiated and executed via reflection.
  • Trigger conditions: An exposed Nutch Server instance with the REST API reachable over the network, with no authentication layer in front of it.
  • Attack vector: Network-based (AV:N); no privileges (PR:N) and no user interaction (UI:N) are required to exploit the flaw.
  • Impact: Successful exploitation allows an unauthenticated attacker to invoke jobs on the server through reflection, which can lead to arbitrary code/job execution and full compromise of confidentiality, integrity, and availability of the affected host.

Affected software

  • Apache Nutch versions 1.10 through 1.22 (inclusive) — specifically the Nutch Server / REST API component.

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade to Apache Nutch 1.23, which removes the Nutch Server component entirely, eliminating the vulnerable REST API attack surface.
  • If patching is not immediately possible: Restrict network access to any instance running the Nutch Server/REST API to trusted users and internal networks only (e.g., via firewall rules, VPN, or network segmentation) to prevent unauthenticated remote access until the upgrade can be completed.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
