A vulnerability was found in java-json-tools jackson-coreutils 2.0. Affected by this issue is the function JsonLoader.fromURL of the file src/main/java/com/github/fge/jackson/JsonLoader.java of the component URL Validation. The manipulation results in server-side request forgery. It is possible to launch the attack remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Server-side request forgery in jackson-coreutils 2.0 allows remote unauthenticated attackers to manipulate the server into issuing arbitrary outbound HTTP requests by supplying a crafted URL to the JsonLoader.fromURL function. The vulnerability originates from insufficient URL validation in the library's JSON loading component, enabling internal network probing, access to cloud metadata endpoints, or interaction with internal services not otherwise reachable. …

Vulnerability AssessmentAI
| Exploitation | The application using jackson-coreutils must pass user-controlled or externally-sourced input directly (or with insufficient sanitization) into the JsonLoader.fromURL function. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) correctly reflects that no authentication or special conditions are required to attempt exploitation, but rates impact at VA:L with all confidentiality and integrity metrics at N - a conservative assessment that likely models a worst-case DoS of the loader function rather than the more typical SSRF impact of internal network traversal and data exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the project maintainer has not responded to the disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
