A vulnerability was found in java-json-tools jackson-coreutils 2.0. Affected by this vulnerability is the function BigDecimal.toPlainString of the file src/main/java/com/github/fge/jackson/JacksonUtils.java. Performing a manipulation results in resource consumption. The attack may be initiated 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
Uncontrolled resource consumption in java-json-tools jackson-coreutils 2.0 allows remote unauthenticated attackers to trigger a denial-of-service condition by submitting crafted input that causes BigDecimal.toPlainString() in JacksonUtils.java to exhaust CPU or memory resources. The root cause is CWE-400 (Uncontrolled Resource Consumption), a well-understood class of vulnerability in Java BigDecimal handling where specially constructed numeric values - such as those with extremely large scale or unscaled value - produce pathologically long string representations. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target application accepts externally-supplied JSON input containing numeric values and passes those values through jackson-coreutils (specifically JacksonUtils.java). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L) rates this 6.9, reflecting a remotely unauthenticated, low-complexity DoS with limited availability impact on the vulnerable system only. … 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 report. … Detailed patch versions, workarounds, and compensating controls in full report. |
