GHSA-q6g2-g7f3-rr83 is a high-severity (CVSS 7.5) CWE-674 vulnerability in org.codehaus.jettison:jettison. 1 public exploit reference exists, so weaponization risk is real. A fix is available for org.codehaus.jettison:jettison — see the affected versions and patch details below.
Jettison vulnerable to infinite recursion
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

Description
An infinite recursion is triggered in Jettison when constructing a JSONArray from a Collection that contains a self-reference in one of its elements. This leads to a StackOverflowError exception being thrown.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.codehaus.jettison:jettison, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.codehaus.jettison:jettison to 1.5.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q6g2-g7f3-rr83 is resolved across your whole dependency graph.
Workarounds
Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.
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.
