CVE-2026-59092: Active Debug Code in juicedata juicefs
JuiceFS through 1.3.1, fixed in commit a46979c, contains an authentication bypass vulnerability that allows unauthenticated remote attackers to access sensitive debug and metrics endpoints by exploiting improper handler registration on the shared http.DefaultServeMux. Attackers can request the /debug/pprof/cmdline endpoint to obtain the process command line containing metadata engine connection strings with database credentials, granting full read/write access to filesystem metadata, while other pprof handlers leak internal state and profiling handlers enable denial of service.
AI Analysis
Technical Summary
CVE-2026-59092 affects JuiceFS through version 1.3.1 and involves an authentication bypass caused by improper handler registration on the shared http.DefaultServeMux. Attackers can remotely access debug and profiling endpoints without authentication. The /debug/pprof/cmdline endpoint reveals the process command line containing metadata engine connection strings with database credentials, enabling full read/write access to filesystem metadata. Other profiling endpoints leak internal state and can be used to cause denial of service. The vulnerability was fixed in a commit identified as a46979c. No official patch or remediation level is explicitly stated in the available data.
Potential Impact
The vulnerability allows unauthenticated remote attackers to bypass authentication controls and access sensitive debug endpoints. This exposure can lead to disclosure of database credentials and full read/write access to filesystem metadata, compromising confidentiality and integrity. Additionally, profiling handlers can leak internal state information and enable denial of service conditions, impacting availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The vulnerability was fixed in commit a46979c, so upgrading to a version including this fix is recommended once available. Until then, restrict access to debug and profiling endpoints and avoid exposing the shared http.DefaultServeMux to untrusted networks.
