A vulnerability was determined in NASA Trick 19.6.0. This issue affects the function JSONVariableServerThread::parse_request of the file trick_source/sim_services/JSONVariableServer/JSONVariableServerThread.cpp of the component TCP Socket Handler. This manipulation causes stack-based buffer overflow. The attack is possible to be carried out remotely. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-82478
This high-severity CVE scores 7.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
