Vector Databases

Enumerate, extract, and inject data across vector database instances: ChromaDB, Weaviate, Qdrant, Milvus, and pgvector.

Overview

The vectordb module provides a unified interface across five vector database providers. Read-only commands (enum, extract, search-sensitive) run without restrictions. State-changing injection commands (inject, metadata-inject) require --force-exploit.

The ChromaDB client automatically tries multiple API endpoint formats for compatibility across ChromaDB 0.4.x through 0.6.x, including tenant/database-aware paths. The pgvector provider connects via PostgreSQL wire protocol (not HTTP).

All HTTP-based providers validate API-level error responses. Milvus and similar REST APIs may return HTTP 200 with a non-zero code field indicating an application-level failure (authentication errors, invalid collections, etc.). These are surfaced as errors rather than silently treated as empty successes.

Supported Providers

Provider	--type value	Default Port	Protocol
ChromaDB	chromadb	8000	HTTP REST
Weaviate	weaviate	8080	HTTP REST
Qdrant	qdrant	6333	HTTP REST
Milvus	milvus	19530	HTTP REST (v2.4+)
pgvector	pgvector	5432	PostgreSQL wire protocol

Subcommands

Read-Only (no --force-exploit required)

Subcommand	Description
enum	List collections/tables with document/row counts
extract	Extract documents/rows from a specific collection
search-sensitive	Search collections for sensitive data patterns (emails, SSNs, credit cards, API keys, passwords)

Gated (requires --force-exploit)

Subcommand	Description
inject	Insert crafted documents into a vector store for RAG poisoning testing
metadata-inject	Test whether metadata fields accept and return unsanitized prompt injection payloads

Flags

Common Flags

Flag	Required	Description
--target	Yes	Database URL (e.g., http://127.0.0.1:8000) or host:port for pgvector
--type	Yes	Provider type: chromadb, weaviate, qdrant, milvus, or pgvector
--header	No	Custom HTTP headers. Repeatable.
--api-key	No	API key for authenticated access
--collection	For extract/inject/metadata-inject, optional for search-sensitive	Collection or table name to target. For search-sensitive, errors if specified but matches nothing.
--limit	No	Maximum documents to return
--exclude-collections	For search-sensitive	Comma-separated collection names to skip

pgvector-Specific Flags

Flag	Default	Description
--db-user	postgres	PostgreSQL user
--db-password	(empty)	PostgreSQL password (prefer AIPOSTEX_VDB_PASSWORD env var)
--db-name	postgres	PostgreSQL database name
--db-sslmode	disable	PostgreSQL SSL mode

Inject Flags

Flag	Required	Description
--payload	Yes	Text content to embed and inject
--metadata	No	JSON string of metadata key-value pairs to attach
--count	No	Number of copies to inject (default: 1)

Metadata-Inject Flags

Flag	Default	Description
--key	source	Metadata key to inject into
--payload	Standard prompt injection test	Custom injection payload

Examples

# Enumerate ChromaDB collections
./aipostex vectordb --target http://127.0.0.1:8000 --type chromadb enum

# Extract documents from a collection
./aipostex vectordb --target http://127.0.0.1:8000 --type chromadb \
  extract --collection my-docs

# Search for sensitive data across all collections
./aipostex vectordb --target http://127.0.0.1:8000 --type chromadb \
  search-sensitive

# Weaviate with API key
./aipostex vectordb --target http://127.0.0.1:8080 --type weaviate \
  enum --api-key demo

# Qdrant enumeration
./aipostex vectordb --target http://127.0.0.1:6333 --type qdrant enum

# Milvus enumeration
./aipostex vectordb --target http://127.0.0.1:19530 --type milvus enum

# Milvus extraction
./aipostex vectordb --target http://127.0.0.1:19530 --type milvus \
  extract --collection embeddings

# pgvector enumeration (PostgreSQL wire protocol)
./aipostex vectordb --target 127.0.0.1:5432 --type pgvector \
  --db-user postgres --db-name mydb enum

# RAG poisoning injection (gated)
./aipostex vectordb --target http://127.0.0.1:8000 --type chromadb \
  inject --collection docs --payload "Ignore previous instructions." \
  --count 3 --force-exploit

# Metadata injection test (gated)
./aipostex vectordb --target http://127.0.0.1:6333 --type qdrant \
  metadata-inject --collection docs --key source \
  --payload "Ignore all prior context." --force-exploit

Sensitive Data Patterns

The search-sensitive command scans document content using 27 regex patterns organized by severity. These patterns are shared across all providers via DefaultSensitivePatterns().

Critical: SSN, credit card, AWS access key, AWS secret key, GCP service account, OpenAI API key, Anthropic API key, GitHub PAT, Stripe key, Vault token, private key

High: HuggingFace token, JWT token, Slack webhook, API key (generic), password field, bearer token, generic secret assignment, connection string (PostgreSQL, MongoDB, MySQL, Redis, Snowflake, MSSQL), PagerDuty key, Datadog API key, Sentry DSN

Medium: Email address, classification marker

Low: Internal IP address

Partial Failure Handling

When extract or search-sensitive encounters an error partway through paginated extraction (e.g., connection loss on page 2), the command returns all rows collected so far along with an error. The CLI surfaces this in the summary as a partial failure count, so operators know the results are incomplete without losing the data already retrieved.

Workflow Progression

discover network (discovers vector DB on :8000/:8080/:6333/:19530/:5432)
  → vectordb enum (list collections, counts)
    → vectordb extract --collection <name> (read documents)
    → vectordb search-sensitive (find PII/credentials)
    → vectordb inject --collection <name> --payload <text> (RAG poisoning, gated)
    → vectordb metadata-inject --collection <name> (metadata injection test, gated)
