Summary
CVE-2026-75338 is an improper access control vulnerability (CWE-284) in Disconf, an open-source distributed configuration management platform, version 2.6.36. Several configuration-fetching API endpoints are explicitly whitelisted in the application’s login interceptor, allowing unauthenticated remote attackers to retrieve all stored configuration items and configuration files, including embedded plaintext credentials. The flaw carries a CVSS v3.1 base score of 9.8 (Critical).
Technical details
- Root cause: the
LoginInterceptorcomponent whitelists the paths/api/config/item,/api/config/file,/api/config/list, and/api/config/simple/listin its "do not intercept" path list, so requests to these endpoints bypass the platform’s authentication checks entirely. - Trigger condition: a simple unauthenticated HTTP GET request to any of the four endpoints (e.g.,
/api/config/list?app=<name>&env=<env>&version=<version>) returns configuration data without any credential or session token. - Attack vector: Network — no privileges and no user interaction are required (AV:N/AC:L/PR:N/UI:N).
- Impact: full disclosure of configuration items and configuration files, which can include database passwords, Redis credentials, API keys, and other connection-string secrets stored in plaintext by the config center. Confidentiality, integrity, and availability impacts are all rated High under the CVSS vector, reflecting the potential for these disclosed credentials to enable further compromise of downstream systems.
Affected software
- Disconf (distributed configuration management platform), version 2.6.36
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: No vendor-supplied patched version has been identified in the CVE record; check with the Disconf project/maintainers for an updated release that removes the four affected paths from the authentication bypass list.
- If no patch is available:
- Restrict network access to the Disconf config-center endpoints (
/api/config/item,/api/config/file,/api/config/list,/api/config/simple/list) to trusted internal hosts only, using firewall rules, network segmentation, or a reverse proxy that enforces authentication. - Do not expose Disconf management interfaces directly to the internet.
- Rotate any credentials (database passwords, Redis credentials, API keys) that may have been stored in Disconf configuration items or files, since they should be considered potentially exposed.
- Monitor access logs for requests to the affected endpoints from unexpected or external IP addresses.
- Restrict network access to the Disconf config-center endpoints (
