CVE-2024-47529: OPENC3 Cosmos

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. OpenC3 COSMOS stores the password of a user unencrypted in the LocalStorage of a web browser. This makes the user password susceptible to exfiltration via Cross-site scripting (see GHSL-2024-128). This vulnerability is fixed in 5.19.0. This only affects Open Source edition, and not OpenC3 COSMOS Enterprise Edition.

Affected products

• OPENC3 Cosmos: before 5.19.0 (fixed in 5.19.0)
