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, notably the /debug/pprof/cmdline endpoint, which reveals process command line information containing metadata engine connection strings and database credentials. This exposure allows attackers to gain full read/write access to filesystem metadata. Additional profiling handlers leak internal state and can be exploited to cause denial of service. The vulnerability was fixed in a commit identified as a46979c. No official patch or remediation level is provided in the available data.
Potential Impact
The vulnerability allows unauthenticated remote attackers to bypass authentication controls and access sensitive debug endpoints. Exposure of database credentials through the /debug/pprof/cmdline endpoint can lead to full read/write access to filesystem metadata, compromising data integrity and confidentiality. Other profiling endpoints leak internal application state and can be leveraged to cause denial of service, 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 or disable debug handlers if possible to mitigate exposure.
