How severe is GHSA-rgv9-q543-rqg4?

GHSA-rgv9-q543-rqg4 has a CVSS score of 7.5/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-rgv9-q543-rqg4?

GHSA-rgv9-q543-rqg4 affects the following packages: com.fasterxml.jackson.core:jackson-databind (Maven), com.fasterxml.jackson.core:jackson-databind (Maven). Ecosystems affected: Maven.

How do I fix GHSA-rgv9-q543-rqg4?

Update com.fasterxml.jackson.core:jackson-databind to 2.12.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rgv9-q543-rqg4 is resolved across your whole dependency graph.

How do I detect GHSA-rgv9-q543-rqg4 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.fasterxml.jackson.core:jackson-databind, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-rgv9-q543-rqg4 if there is no patch (or I can't update yet)?

Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.

Is GHSA-rgv9-q543-rqg4 actively exploited in the wild?

Yes. There are 2 known exploit references for GHSA-rgv9-q543-rqg4, including 2 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. 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 GHSA-rgv9-q543-rqg4?

GHSA-rgv9-q543-rqg4 has an EPSS (Exploit Prediction Scoring System) score of 3.4%, placing it in the 89th 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 GHSA-rgv9-q543-rqg4?

GHSA-rgv9-q543-rqg4 is classified as Deserialization of Untrusted Data (CWE-502). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-rgv9-q543-rqg4 published, and has it been updated?

GHSA-rgv9-q543-rqg4 was published on October 3, 2022 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

In FasterXML jackson-databind before 2.12.7.1 and in 2.13.x before 2.13.4, resource exhaustion can occur because of a lack of a check in BeanDeserializer._deserializeFromArray to prevent use of deeply nested arrays. This issue can only happen when the UNWRAP_SINGLE_VALUE_ARRAYS feature is explicitly enabled.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
