SCA: security update for openc3 (GHSA-wgx6-g857-jjf7)

high Tenable Self-Hosted Container Security Plugin ID 440749

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more
embedded systems. Prior to versions 6.10.5 and 7.0.0-rc3, the OpenC3 password change functionality allows
a user to change their password without providing the old password, by accepting a valid session token
instead. In assumed breach scenarios, this behaviour can be exploited by an attacker who has already
obtained a valid session token, to gain persistence in hijacked account (including admin) and prevent
legitimate users from accessing the account. This issue has been patched in versions 6.10.5 and 7.0.0-rc3.
(CVE-2026-42084)

Solution

Update the openc3 library and its related packages to version 6.10.5 or later.
