CVE-2026-109405 conductor-oss CVE debrief

Who should care

Defenders responsible for systems using conductor-oss conductor versions up to 3.33.0-rc10 should assess exposure and verify the impact of server-side request forgery on their systems.

Why it matters

Defenders should prioritize verifying exposure of conductor-oss conductor versions up to 3.33.0-rc10 and assess the impact of server-side request forgery on their systems.

• Verify exposure of conductor-oss conductor versions up to 3.33.0-rc10
• Assess the impact of server-side request forgery on systems using conductor-oss conductor
• Remediate by updating conductor-oss conductor to a version beyond 3.33.0-rc10 if available
• Monitor systems for signs of server-side request forgery attacks

Technical summary

The vulnerability affects the function KafkaPublishTask.start of the file kafka/src/main/java/com/netflix/conductor/contribs/tasks/kafka/KafkaPublishTask.java in conductor-oss conductor up to 3.33.0-rc10. The manipulation of the argument kafka_request.bootStrapServers results in server-side request forgery. Defenders should prioritize verifying exposure of conductor-oss conductor versions up to 3.33.0-rc10 and assess the impact of server-side request forgery on their systems. This involves reviewing the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance, and planning vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Defensive priority

Defenders should prioritize verifying exposure of conductor-oss conductor versions up to 3.33.0-rc10 and assess the impact of server-side request forgery on their systems.

Recommended defensive actions

• Verify exposure of conductor-oss conductor versions up to 3.33.0-rc10
• Assess the impact of server-side request forgery on systems using conductor-oss conductor
