Agent Security Vulnerability

An Agent Security Vulnerability is a vulnerability that is an AI system weakness enabling malicious exploitation of AI agents through adversarial attacks, unauthorized access, or behavioral manipulation (within agent deployment environments).

• AKA: AI Agent Security Weakness, Agent Attack Vector, Agent Exploitation Point, Agent Security Gap.
• Context:
  • It can typically manifest as Prompt Injection Vulnerability through hidden instruction insertion, context manipulation, and directive override.
  • It can typically enable Data Exfiltration Attacks via memory extraction, credential harvesting, and sensitive information leakage.
  • It can typically facilitate Agent Behavioral Manipulation through goal misalignment, reward hacking, and objective subversion.
  • It can typically arise from Insufficient Input Validation in user prompt processing, external data ingestion, and tool response handling.
  • It can typically exploit Context Window Limitations through memory overflow attacks, context pollution, and attention manipulation.
  • ...
  • It can often target Multi-Agent Communication Channels through message interception, agent impersonation, and protocol exploitation.
  • It can often leverage Tool Integration Weaknesses via API abuse, resource exhaustion, and unauthorized function calls.
  • It can often exploit Model Training Artifacts including backdoor triggers, poisoned training data, and adversarial examples.
  • It can often bypass Security Control Mechanisms through jailbreaking techniques, constraint violation, and safety filter evasion.
  • ...
  • It can range from being a Low-Severity Agent Security Vulnerability to being a Critical Agent Security Vulnerability, depending on its exploitation impact.
  • It can range from being a Design-Level Agent Security Vulnerability to being an Implementation-Level Agent Security Vulnerability, depending on its origin layer.
  • It can range from being a Single-Agent Security Vulnerability to being a System-Wide Security Vulnerability, depending on its propagation scope.
  • It can range from being a Detectable Security Vulnerability to being a Zero-Day Security Vulnerability, depending on its discovery status.
  • ...
  • It can be mitigated through Agent Security Frameworks implementing defense mechanisms.
  • It can be detected by Security Monitoring Systems using anomaly detection.
  • It can be prevented via Input Sanitization Layers and output validation.
  • It can be addressed through Agent Governance Frameworks with security policy.
  • It can be managed by Security Patch Management and vulnerability assessment.
  • ...
• Example(s):
  • Prompt Injection Attacks, manipulating agent behavior through crafted inputs.
  • Indirect Prompt Injections, embedding malicious instructions in external content.
  • Agent Poisoning Attacks, such as:
    • Training Data Poisoning affecting model behavior.
    • Fine-tuning Attacks introducing backdoor behavior.
  • Resource Exploitation Vulnerabilitys, such as:
    • Token Exhaustion Attacks depleting computational resources.
    • API Rate Limit Bypass overwhelming external services.
  • ...
• Counter-Example(s):
  • Secured Agent Interface, which implements proper validation.
  • Isolated Execution Environment, which prevents system access.
  • Read-Only Agent Configuration, which blocks modification attempts.
