Low risk33th percentile - higher than 33% of all known CVEs
Summary
ArchiveBox versions 0.8.6rc0 and earlier have a vulnerability in the /add/ endpoint. The config JSON field is merged into the crawl config without validation, allowing injection of tool arguments and remote code execution (RCE).
Risk Assessment
Attackers can execute arbitrary commands on the server, leading to full system compromise and archival data loss.
Recommendation
No public patches are available yet. Restrict access to the /add/ endpoint and do not trust untrusted config data.
Original NVD description (English source)
ArchiveBox is an open source self-hosted web archiving system. In versions 0.8.6rc0 and prior, 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. At time of publication, there are no publicly available patches.
