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.

CVE-2026-19502 (GCVE-0-2026-19502)

Vulnerability from cvelistv5 – Published: 2026-08-12 20:14 – Updated: 2026-08-13 12:46

Title
Insufficient redaction of sensitive configuration values in diagnostic output of MongoDB SQL Schema Builder CLI
Summary
MongoDB SQL Schema Builder CLI records its startup configuration to standard output and, when file logging is enabled, to a log file on disk. Certain connection settings were written without redaction, so authentication material supplied by the operator could appear in plaintext in that diagnostic output. A local user with read access to the terminal session or the log directory, or anyone with access to a location where those logs are subsequently collected, could obtain those values.

CVE-2026-19363 (GCVE-0-2026-19363)

Vulnerability from cvelistv5 – Published: 2026-08-09 17:45 – Updated: 2026-08-11 01:48

Title
lmammino oidc-authorizer Lambda Authorizer handler.rs log file
Summary
A vulnerability was found in lmammino oidc-authorizer up to 0.4.0. Impacted is an unknown function of the file src/handler.rs of the component Lambda Authorizer. The manipulation results in sensitive information in log files. The attack can be executed remotely. `src/handler.rs` logs raw Authorization header values and complete bearer tokens/JWTs on authentication failure paths, potentially exposing credentials through CloudWatch Logs. `src/models.rs` serializes the complete validated JWT claims set with `serde_json::to_string(token_claims).unwrap()` and propagates it through `context["jwtClaims"]` to downstream integrations. This code performs serialization, not deserialization, and does not process attacker-controlled `jwtClaims` input. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

The attack can be executed remotely. `src/handler.rs` logs raw Authorization header values and complete bearer tokens/JWTs on authentication failure paths, potentially exposing credentials through CloudWatch Logs. `src/models.rs` serializes the complete validated JWT claims set with `serde_json::to_string(token_claims).unwrap()` and propagates it through `context[\"jwtClaims\"]` to downstream integrations. This code performs serialization, not deserialization, and does not process attacker-controlled `jwtClaims` input. The exploit has been made public and could be used.

CVE-2026-18710 (GCVE-0-2026-18710)

Vulnerability from cvelistv5 – Published: 2026-08-11 22:00 – Updated: 2026-08-12 12:41

Title
Cleartext Storage of Sensitive Information in MongoDB Driver Logging During Client Initialization
Summary
A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only.

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.
