AI Analysis
Technical Summary
CVE-2026-86506 is a medium severity vulnerability in JetBrains GoLand prior to version 2026.2.2.1. The GoLand profiler's injected pprof server does not require authentication, which exposes profiling data to unauthorized parties. This is classified under CWE-306, indicating missing authentication for a critical function. The CVSS 3.1 vector is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N, reflecting network attack vector, high attack complexity, no privileges or user interaction required, unchanged scope, and high confidentiality impact without integrity or availability impact. No vendor advisory or patch information is currently available.
Potential Impact
The vulnerability allows unauthorized remote attackers to access profiling data from the GoLand profiler's injected pprof server. This exposure could lead to leakage of sensitive information contained in profiling data. There is no indication of impact on integrity or availability. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the GoLand profiler's pprof server to trusted users only to mitigate unauthorized access.
