CVE-2026-20708 (GCVE-0-2026-20708)

Vulnerability from cvelistv5 – Published: 2026-08-11 16:25 – Updated: 2026-08-12 15:55
VLAI
Summary
Insertion of sensitive information into log file in the subsystem for the Intel(R) AMT and Intel(R) Standard Manageability may allow an information disclosure. Network adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via network access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

CVE-2026-20205 (GCVE-0-2026-20205)

Vulnerability from cvelistv5 – Published: 2026-04-15 15:17 – Updated: 2026-04-15 17:39

Title
Sensitive Information Disclosure in ''_internal'' index in Splunk MCP Server app
Summary
In Splunk MCP Server app versions below 1.0.3 , a user who holds a role with access to the Splunk `_internal` index or possesses the high-privilege capability `mcp_tool_admin` could view users session and authorization tokens in clear text.<br><br>The vulnerability would require either local access to the log files or administrative access to internal indexes, which by default only the admin role receives. <br><br>Review roles and capabilities on your instance and restrict internal index access to administrator-level roles. See [Define roles on the Splunk platform with capabilities](https://docs.splunk.com/Documentation/Splunk/latest/Security/Rolesandcapabilities) and [Connecting to MCP Server and Admin settings](https://help.splunk.com/en/splunk-enterprise/mcp-server-for-splunk-platform/connecting-to-mcp-server-and-admin-settings) in the Splunk documentation for more information.

Mitigation
Architecture and Design Implementation

Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.

Mitigation
Distribution

Remove debug log files before deploying the application into production.

Mitigation
Operation

Protect log files against unauthorized read/write.

Mitigation
Implementation

Adjust configurations appropriately when software is transitioned from a debug state to production.

CAPEC-215: Fuzzing for application mapping

An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash.
