Questions about CVE-2026-104989
Is CVE-2026-104989 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The flaw allows code to run on the host before any login is required. The injected code runs with the highest available privileges (SYSTEM), which can fully compromise the affected machine.Source: github.com
Which versions are affected by CVE-2026-104989?
V-Ray Swarm: through 2.0.19.Source: cve.now feed data
Am I affected, and how do I check?
Chaos V-Ray Swarm versions up to and including 2.0.19 are in the affected range. Compare the installed V-Ray Swarm version against 2.0.19 to see whether it falls in that range.Source: github.com
How do I fix CVE-2026-104989?
The checked facts name no fixed version, so no upgrade target can be given. Check the vendor's advisory for a fix before deciding on an update.Source: github.com
What if there's no patch?
The checked facts name no workaround. Until a fix is available, the vendor's advisory is the place to look for any mitigation.Source: github.com
