Title
Insecure direct object reference in Strands Agents Tools memory tool namespace isolation
Summary
Insecure direct object reference in the mongodb_memory, elasticsearch_memory, and mem0_memory tools in Amazon Strands Agents Tools before 0.8.3 might allow remote authenticated users to access, modify, or delete memories belonging to other tenants by influencing the LLM to emit tool calls with a forged namespace parameter.
To remediate this issue, users should upgrade to version 0.8.3.

Title
Incorrect authorization in the aggregation pipeline tool in Amazon AWS Labs DocumentDB MCP Server
Summary
Incorrect authorization in the aggregation pipeline tool in Amazon AWS Labs DocumentDB MCP Server before 1.0.12 might allow an authenticated MCP client to perform inappropriate write operations on the connected database via write-capable aggregation pipeline stages that bypass the read-only mode enforcement logic.
To remediate this issue, users should upgrade to version 1.0.12 or later.

Title
Prompt injection bypasses shell tool consent gate in Strands Agents Tools
Summary
A prompt injection vulnerability in the shell tool in Amazon Strands Agents Tools before 0.8.0 might allow remote actors to execute arbitrary operating system commands on the agent's host via a crafted prompt that sets the non_interactive parameter to true, bypassing the human consent gate.
To remediate this issue, users should upgrade to version 0.8.0.

Title
Broker Credential and OAuth Token Disclosure in AWS Labs Amazon MQ MCP Server via Prompt Injection
Summary
Improper restriction of intended endpoints in the RabbitMQ broker connection tools of the Amazon MQ MCP Server (awslabs.amazon-mq-mcp-server) before 2.0.24 may allow a remote unauthenticated actor (via prompt injection) to obtain Amazon MQ for RabbitMQ broker credentials or OAuth access tokens sent to a crafted endpoint controlled through a broker hostname introduced in the MCP client context.
To remediate this issue, users should upgrade to version 2.0.24.

Title
Disabled SSH host key verification in Amazon AWS CLI EMR helper commands
Summary
Key exchange without entity authentication in the EMR SSH helper commands in Amazon AWS CLI before 1.45.28 and AWS CLI v2 before 2.35.3 might allow man-in-the-middle attackers to intercept SSHsessions and file transfers via network positioning between the client and the EMR cluster endpoint.
To remediate this issue, users should upgrade to AWS CLI v1 1.45.28 or later, or AWS CLI v2 2.35.3 or later.

Title
Incorrect authorization in Strands Agents Tools http_request proxy credential exfiltration
Summary
Incorrect authorization in the http_request tool in Strands Agents Tools before 0.8.2 might allow remote attackers to obtain credentials configured via HTTP_REQUEST_TOKEN_CONFIG by influencing the LLM to route requests through actor-controlled proxy infrastructure.
To remediate this issue, users should upgrade to version 0.8.2.

Title
Stored XSS in Participant URL Field leads to Account Takeover via Session Token Theft
Summary
Stored cross-site scripting in the participant URL handling in AWS Ops
Wheel before PR #168 might allow an authenticated remote user to steal
session tokens and escalate to full administrative control of the
deployed instance via a crafted participant_url value containing a
dangerous URI scheme.
To remediate this issue, users should redeploy from the latest version of aws-ops-wheel.

Title
Insecure direct object reference in Strands Agents Tools memory tool namespace isolation
Summary
Insecure direct object reference in the mongodb_memory, elasticsearch_memory, and mem0_memory tools in Amazon Strands Agents Tools before 0.8.3 might allow remote authenticated users to access, modify, or delete memories belonging to other tenants by influencing the LLM to emit tool calls with a forged namespace parameter.
To remediate this issue, users should upgrade to version 0.8.3.

Title
Incorrect authorization in the aggregation pipeline tool in Amazon AWS Labs DocumentDB MCP Server
Summary
Incorrect authorization in the aggregation pipeline tool in Amazon AWS Labs DocumentDB MCP Server before 1.0.12 might allow an authenticated MCP client to perform inappropriate write operations on the connected database via write-capable aggregation pipeline stages that bypass the read-only mode enforcement logic.
To remediate this issue, users should upgrade to version 1.0.12 or later.

Summary
Improper limitation of a pathname to a restricted directory in the get_resource tool in Amazon awslabs.aws-transform-mcp-server 0.1.0 through 0.1.4 might allow a context-dependent actor to write arbitrary files outside the intended working directory via the savePath parameter.

Title
Prompt injection bypasses shell tool consent gate in Strands Agents Tools
Summary
A prompt injection vulnerability in the shell tool in Amazon Strands Agents Tools before 0.8.0 might allow remote actors to execute arbitrary operating system commands on the agent's host via a crafted prompt that sets the non_interactive parameter to true, bypassing the human consent gate.
To remediate this issue, users should upgrade to version 0.8.0.

Title
Disabled SSH host key verification in Amazon AWS CLI EMR helper commands
Summary
Key exchange without entity authentication in the EMR SSH helper commands in Amazon AWS CLI before 1.45.28 and AWS CLI v2 before 2.35.3 might allow man-in-the-middle attackers to intercept SSHsessions and file transfers via network positioning between the client and the EMR cluster endpoint.
To remediate this issue, users should upgrade to AWS CLI v1 1.45.28 or later, or AWS CLI v2 2.35.3 or later.

Broker Credential and OAuth Token Disclosure in AWS Labs Amazon MQ MCP Server via Prompt Injection
Summary
Improper restriction of intended endpoints in the RabbitMQ broker connection tools of the Amazon MQ MCP Server (awslabs.amazon-mq-mcp-server) before 2.0.24 may allow a remote unauthenticated actor (via prompt injection) to obtain Amazon MQ for RabbitMQ broker credentials or OAuth access tokens sent to a crafted endpoint controlled through a broker hostname introduced in the MCP client context.
To remediate this issue, users should upgrade to version 2.0.24.

Title
Stored XSS in Participant URL Field leads to Account Takeover via Session Token Theft
Summary
Stored cross-site scripting in the participant URL handling in AWS Ops
Wheel before PR #168 might allow an authenticated remote user to steal
session tokens and escalate to full administrative control of the
deployed instance via a crafted participant_url value containing a
dangerous URI scheme.
To remediate this issue, users should redeploy from the latest version of aws-ops-wheel.
