Jackson Coreutils
Monthly
Unbounded resource allocation in jackson-coreutils 2.0 exposes any Java application using the library's JSON Pointer parser to remote denial of service. The `TreePointer.tokensFromInput` method in the JSON Pointer parsing component fails to enforce limits on resource allocation when processing attacker-controlled input, allowing a remote unauthenticated attacker to trigger excessive memory or CPU consumption. A public proof-of-concept exists via a GitHub issue report; the project maintainer has not responded to the disclosure, and no patch is available at time of analysis.
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. No public exploit has been incorporated into the CISA KEV catalog, though exploit code was publicly disclosed via a GitHub issue report. The maintainer has not responded to responsible disclosure.
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. A public proof-of-concept exists via the project's GitHub issue tracker, and the maintainer has not responded to the disclosure; no patch is available at time of analysis.
