Openc3

Openc3's vulnerability footprint centers on its Cosmos command-and-control and telemetry platform, a modestly represented but strategically important component in satellite operations and mission-critical command infrastructure. Vulnerabilities affecting the vendor skew strongly toward critical-severity outcomes and recur through weakness classes including path traversal, cross-site scripting, and cleartext storage of sensitive data—flaws characteristic of web-facing mission systems where authentication bypass and credential exposure carry outsized operational risk. Defenders managing Cosmos deployments should treat this vendor's advisories as high-priority and ensure restricted network access to exposed interfaces; live severity and exploitation counts are shown alongside this summary.
