CVE-2026-55882 tilt-dev CVE debrief

Who should care

Users of Tilt dev environments as code for microservice apps on Kubernetes, especially those with network-exposed HUD or apiserver listeners, should be aware of this vulnerability and take necessary precautions to mitigate it. This includes immediately upgrading to Tilt version 0.37.4 or later, limiting network exposure of HUD and apiserver listeners, implementing access controls for /debug handlers, monitoring for suspicious activity, and inventorying Tilt installations for vulnerability.

Technical summary

The Tilt HUD server mounts Go net/http/pprof handlers under /debug with no access control from version 0.19.5 through 0.37.3. This allows unauthenticated callers to read process memory through /debug/pprof/heap and /debug/pprof/goroutine, including session and apiserver tokens, and degrade performance through /debug/pprof/profile or /debug/pprof/trace when the HUD or apiserver listener is network-exposed. Users should be aware of the potential risks and take necessary precautions to mitigate the vulnerability.

Defensive priority

High

Recommended defensive actions

• Immediately upgrade to Tilt version 0.37.4 or later
• Limit network exposure of HUD and apiserver listeners
• Implement access controls for /debug handlers
• Monitor for suspicious activity
• Inventory Tilt installations for vulnerability
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
