From b880ebe5fcfa2ff548cd02b9079e379a64c7878e Mon Sep 17 00:00:00 2001 From: ppcvote Date: Sat, 13 Jun 2026 18:00:18 +0800 Subject: [PATCH 1/2] Add OWASP LLM02 output-side scorer pack: SSRF / SSTI / XXE / open redirect / LDAP Extends the regex true/false scorer family from #1868 with five additional output-side payload detectors, mirroring the existing RegexScorer pattern. Each is deterministic (no LLM call), categorized "security", with unit tests covering positive payloads, benign negatives, rationale, custom patterns, and memory integration. --- pyrit/score/__init__.py | 10 +++ pyrit/score/true_false/regex/__init__.py | 15 +++- .../regex/ldap_injection_output_scorer.py | 59 ++++++++++++++++ .../regex/open_redirect_output_scorer.py | 62 ++++++++++++++++ .../true_false/regex/ssrf_output_scorer.py | 63 +++++++++++++++++ .../true_false/regex/ssti_output_scorer.py | 54 ++++++++++++++ .../true_false/regex/xxe_output_scorer.py | 58 +++++++++++++++ .../test_ldap_injection_output_scorer.py | 70 +++++++++++++++++++ .../regex/test_open_redirect_output_scorer.py | 67 ++++++++++++++++++ .../score/regex/test_ssrf_output_scorer.py | 69 ++++++++++++++++++ .../score/regex/test_ssti_output_scorer.py | 69 ++++++++++++++++++ .../score/regex/test_xxe_output_scorer.py | 67 ++++++++++++++++++ 12 files changed, 661 insertions(+), 2 deletions(-) create mode 100644 pyrit/score/true_false/regex/ldap_injection_output_scorer.py create mode 100644 pyrit/score/true_false/regex/open_redirect_output_scorer.py create mode 100644 pyrit/score/true_false/regex/ssrf_output_scorer.py create mode 100644 pyrit/score/true_false/regex/ssti_output_scorer.py create mode 100644 pyrit/score/true_false/regex/xxe_output_scorer.py create mode 100644 tests/unit/score/regex/test_ldap_injection_output_scorer.py create mode 100644 tests/unit/score/regex/test_open_redirect_output_scorer.py create mode 100644 tests/unit/score/regex/test_ssrf_output_scorer.py create mode 100644 tests/unit/score/regex/test_ssti_output_scorer.py create mode 100644 tests/unit/score/regex/test_xxe_output_scorer.py diff --git a/pyrit/score/__init__.py b/pyrit/score/__init__.py index 9924ea7904..b545cd5868 100644 --- a/pyrit/score/__init__.py +++ b/pyrit/score/__init__.py @@ -48,15 +48,20 @@ from pyrit.score.true_false.regex.anthrax_keyword_scorer import AnthraxKeywordScorer from pyrit.score.true_false.regex.credential_leak_scorer import CredentialLeakScorer from pyrit.score.true_false.regex.fentanyl_keyword_scorer import FentanylKeywordScorer +from pyrit.score.true_false.regex.ldap_injection_output_scorer import LDAPInjectionOutputScorer from pyrit.score.true_false.regex.markdown_injection import MarkdownInjectionScorer from pyrit.score.true_false.regex.meth_keyword_scorer import MethKeywordScorer from pyrit.score.true_false.regex.nerve_agent_keyword_scorer import NerveAgentKeywordScorer +from pyrit.score.true_false.regex.open_redirect_output_scorer import OpenRedirectOutputScorer from pyrit.score.true_false.regex.path_traversal_output_scorer import PathTraversalOutputScorer from pyrit.score.true_false.regex.regex_scorer import RegexScorer from pyrit.score.true_false.regex.shell_command_output_scorer import ShellCommandOutputScorer from pyrit.score.true_false.regex.sql_injection_output_scorer import SQLInjectionOutputScorer +from pyrit.score.true_false.regex.ssrf_output_scorer import SSRFOutputScorer +from pyrit.score.true_false.regex.ssti_output_scorer import SSTIOutputScorer from pyrit.score.true_false.regex.static_prompt_injection_scorer import StaticPromptInjectionScorer from pyrit.score.true_false.regex.xss_output_scorer import XSSOutputScorer +from pyrit.score.true_false.regex.xxe_output_scorer import XXEOutputScorer from pyrit.score.true_false.self_ask_category_scorer import ContentClassifierPaths, SelfAskCategoryScorer from pyrit.score.true_false.self_ask_general_true_false_scorer import SelfAskGeneralTrueFalseScorer from pyrit.score.true_false.self_ask_question_answer_scorer import SelfAskQuestionAnswerScorer @@ -128,6 +133,8 @@ def __getattr__(name: str) -> object: "ConsoleScorerPrinter", "ConversationScorer", "CredentialLeakScorer", + "LDAPInjectionOutputScorer", + "OpenRedirectOutputScorer", "DecodingScorer", "FentanylKeywordScorer", "create_conversation_scorer", @@ -181,6 +188,8 @@ def __getattr__(name: str) -> object: "ScorerPrinter", "ShellCommandOutputScorer", "SQLInjectionOutputScorer", + "SSRFOutputScorer", + "SSTIOutputScorer", "StaticPromptInjectionScorer", "SubStringScorer", "TrueFalseCompositeScorer", @@ -193,4 +202,5 @@ def __getattr__(name: str) -> object: "VideoFloatScaleScorer", "VideoTrueFalseScorer", "XSSOutputScorer", + "XXEOutputScorer", ] diff --git a/pyrit/score/true_false/regex/__init__.py b/pyrit/score/true_false/regex/__init__.py index 95b15fc224..922b0a9cef 100644 --- a/pyrit/score/true_false/regex/__init__.py +++ b/pyrit/score/true_false/regex/__init__.py @@ -3,34 +3,45 @@ """ Regex-based true/false scorers for detecting credential leaks, OWASP LLM02 -insecure-output payloads (XSS, SQL injection, shell commands, path traversal), -prompt injection, markdown injection, and CBRN/illicit-substance keywords. +insecure-output payloads (XSS, SQL injection, shell commands, path traversal, +SSRF, SSTI, XXE, open redirect, and LDAP injection), prompt injection, +markdown injection, and CBRN/illicit-substance keywords.
