Apache Skywalking 9.7.0 – 10.4.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NSummary
CVE-2026-30778 is a high-severity Exposure of Sensitive Information Through Data Queries (CWE-202) vulnerability in Apache Skywalking. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Information Repositories (T1213); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-23 (Data Mining Protection) — see the control section below for these in your framework.

CVE-2026-30778 is a vulnerability in the Apache SkyWalking OAP server that allows the /debugging/config/dump endpoint to leak sensitive configuration information for MySQL and PostgreSQL databases. This issue affects versions of Apache SkyWalking from 9.7.0 through 10.3.0 and is classified under CWE-202 (Observable Discrepancy), with a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact.
An unauthenticated attacker with network access can exploit this vulnerability by directly accessing the exposed /debugging/config/dump endpoint, requiring low complexity and no user interaction. Successful exploitation enables the attacker to retrieve sensitive database configuration details, potentially exposing credentials or other critical data without impacting integrity or availability.
The Apache SkyWalking security advisory recommends upgrading to version 10.4.0, which addresses the issue by fixing the endpoint behavior. Additional details are available in the official Apache announcement at https://lists.apache.org/thread/pvf35o3tp1rqhmrhzj6fg31gvqrqcvn3 and the OSS-Security mailing list post at http://www.openwall.com/lists/oss-security/2026/04/15/2.

AC-23 directly requires mechanisms to protect against unauthorized data mining and inference from statistical queries that would expose sensitive information.

Least-privilege query permissions directly limit the data an attacker can request or infer.
Behavior analytics on query activity can detect inference attempts but does not prevent exposure at query time.
Protecting data-in-use reduces what remains available for inference via queries.

Access control limits who can run queries that could expose sensitive information via inference.
Granular access rights reduce the ability of users to craft inference queries.
Data masking prevents inference by obscuring sensitive values returned in query results.
Information access restriction directly limits query scope that could lead to inference.
Classification helps identify sensitive data that must be protected from inference attacks.
DLP can detect and block queries or result sets that risk exposing sensitive information.
