ArchiveBox Vulnerable to RCE via unvalidated per-crawl config overrides in AddView
GitHub lists this reviewed advisory for archivebox. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
9.8 critical
GitHub source severity; exploitability and local consequence require separate evidence.

02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
archivebox
source listed<= 0.8.6rc0
The /add/ endpoint (AddView in core/views.py) accepts a config JSON field that gets merged into the crawl config without validation. This config is exported as environment variables when archive plugins run, allowing injection of arbitrary tool arguments to achieve RCE. When PUBLIC_ADD_VIEW=True (common for bookmarklet usage), this is exploitable without authentication. The endpoint is also @csrf_exempt. Affected code: core/views.py:887 - user config extracted with no validation: custom_config = form.cleaned_data.get("config") or {} core/views.py:918 - merged into crawl config: config.update(custom_config) config/configset.py:255-256 - crawl config applied with high priority: if crawl and hasattr(crawl, "config") and crawl.config: config.update(crawl.config) hooks.py:398-411 - config exported as env vars: for key, value in config.items(): if key in SKIP_KEYS: continue env[key] = str(value) plugins/ytdlp/on_Snapshot__02_ytdlp.bg.py:122-123 - env var args passed to yt-dlp: ytdlp_args_extra = get_env_array("YTDLP_ARGS_EXTRA", []) cmd.extend(ytdlp_args_extra) PoC (pre-auth when PUBLIC_ADD_VIEW=True): curl -X POST http://localhost:8000/add/ \
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
