CVE-2026-42601
ArchiveBox Vulnerable to RCE via unvalidated per-crawl config overrides in AddView
Description

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.

Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 4.0 CRITICAL [email protected]
Solution
Prevent RCE by validating configuration input and avoiding unvalidated merges into crawl config.
  • Validate all configuration fields in the /add/ endpoint.
  • Do not merge unvalidated configuration directly into crawl config.
  • Sanitize all user-supplied configuration values.
  • Limit the scope of environment variables for plugins.
