HIGHFix: FasterXML/jackson-databind@0a8157cGHSA-57j2-w4cx-62h2 is a high-severity (CVSS 7.5) Out-of-bounds Write vulnerability in com.fasterxml.jackson.core:jackson-databind. 1 public exploit reference exists, so weaponization risk is real. A fix is available for com.fasterxml.jackson.core:jackson-databind — see the affected versions and patch details below.
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
jackson-databind is a data-binding package for the Jackson Data Processor. jackson-databind allows a Java stack overflow exception and denial of service via a large depth of nested objects.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update com.fasterxml.jackson.core:jackson-databind to 2.13.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-57j2-w4cx-62h2 is resolved across your whole dependency graph.
Workarounds
Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
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.
CodeReady Studio is no longer supported and therefore this flaw will not be addressed in CodeReady Studio.
