OWASP LLM Top 10 ranking for prompt injection (LLM01:2025)
// THREAT REALITY

Prompt Injection Is Not a Future Risk. It's Happening in Production.

Prompt injection is ranked LLM01:2025 — the #1 threat in the OWASP LLM Top 10. It enables attackers to override your system prompt, exfiltrate data, misuse your tools, and impersonate trusted personas — all through the same input channel your users type in every day.

67% of attacks target customer-facing chatbots. The attack surface is everywhere you accept user input and feed it to an LLM — which is to say, your entire product.

⚠
Instruction Override
Attackers craft inputs that redirect your LLM to ignore its system prompt and execute attacker-controlled instructions.
⚠
Data Exfiltration
Malicious prompts extract system instructions, user data from context, or information from connected data sources.
⚠
Compliance Exposure
An unaudited LLM application is an open compliance gap. EU AI Act, SOC 2, and enterprise vendor questionnaires ask for proof — not assurances.
Running a scanner is not the same as having an audit.

A scanner output is a log file. An audit is a documented set of findings — severity-rated, evidence-backed, mapped to frameworks, and signed off by a human expert. When a CISO, enterprise buyer, or regulator asks for proof that your LLM is secure, they are asking for the audit. The scanner cannot give them that.

// WE ALREADY HAVE PROMPT TOOLING

Prompt management tools are built for your dev team. Audits are built for the security buyer.

Prompt management tools help engineering teams evaluate output quality, iterate on prompts faster, and improve developer workflow. They serve product and engineering velocity. They do not create the audit evidence a CISO, compliance lead, or enterprise buyer needs.

These tools are not designed to issue formal findings, assign CVSS-style severity, map evidence to frameworks, or deliver a remediation roadmap for auditors. That gap is the point of this audit.

// ATTACK SURFACE COVERAGE

60 Test Cases. 10 Attack Categories.

Each test targets a named threat — not a vague security concept. Mapped to OWASP LLM Top 10 categories and graded by impact, exploitability, and reliability.

CAT-01CRITICAL
Direct Instruction Override
Adversarial inputs that override your system prompt and redirect the model to attacker-controlled instructions.
→ Definition
CAT-02HIGH
Role-Playing & Authority Confusion
DAN-style jailbreaks, developer console impersonation, and fictional framing attacks that bypass safety constraints.
→ Definition
CAT-03HIGH
Delimiter & Structured-Format Injection
Structured-format attacks using JSON, XML, markdown, and delimiter tricks to escape context boundaries or override trusted fields.
→ Definition
CAT-04HIGH
Multi-Turn Persistence & Memory Poisoning
Memory-seeding and persistence attacks that contaminate later turns or stored conversation state.
→ Definition
CAT-05CRITICAL
Indirect & Second-Order Injection
Malicious instructions embedded in documents, URLs, tool call outputs, or RAG-retrieved content.
→ Definition
CAT-06CRITICAL
Data Exfiltration & Prompt Leakage
System prompt extraction, PII exfiltration, canary detection, and confidential context extraction.
→ Definition
CAT-07HIGH
Jailbreaks & Safety Bypass
Jailbreak attempts, role-play pivots, and safety-bypass patterns that coerce unsafe or policy-breaking behavior.
→ Definition
CAT-08CRITICAL
Tool Misuse & Action Escalation
Attacks that hijack function calls, escalate tool permissions, or trigger unintended agentic actions.
→ Definition
CAT-09HIGH
Encoding, Obfuscation & Translation
Encoded, obfuscated, or translated payloads that hide malicious intent from filters and reviewers.
→ Definition
CAT-10HIGH
Retrieval, Citation & Source-Manipulation
Source poisoning, citation steering, and retrieval manipulation that cause the model to trust attacker-shaped context.
→ Definition

SAMPLE FINDING — REDACTEDSEVERITY: CRITICAL
FINDING ID
CVX-2026-0042
OWASP MAPPING
LLM01:2025 / LLM06:2025
DESCRIPTION
The target application fails to reject role-escalation inputs that impersonate a developer console persona. A submitted test case using RC-01 [REDACTED] successfully overrode the system prompt and elicited [REDACTED]. Exploitability: High. Reliability: Consistent across 3 test runs.
REMEDIATION
Implement input validation to detect and reject persona-switch patterns. Enforce strict system prompt immutability via [REDACTED]. Add output classification to flag [REDACTED] responses before delivery to the user.
