- Critical · CVSS 3.1
- Exploit chance (EPSS)
- 1.00%
- Chance of exploitation in the next 30 days. Higher than 62.76% of scored vulnerabilities.
- Known exploited
- No
- Not in CISA's catalog
- Weakness
- CWE-942 Permissive Cross-domain Security Policy with Untrusted Domains
- Fix
9.7.0- Upgrade directus to this version or later
Description
Impact
The default value for the CORS_ENABLED and CORS_ORIGIN configuration was set to be very permissive by default. This could lead to unauthorized access in uncontrolled environments when the configuration hasn't been changed.
Patches
The default values for CORS have been changed in https://github.com/directus/directus/pull/12022 which is released under 9.7.0
Workarounds
Configure the CORS environment variables to match your project's usage, rather than leaving them at the (permissive) defaults.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-942: Permissive Cross-domain Security Policy with Untrusted Domains
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.
How to prevent it
- Architecture and Design, Operation: Define a restrictive Content Security Policy [REF-1486] or cross-domain policy file.
- Architecture and Design, Operation: Avoid using wildcards in the CSP / cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.
- Architecture and Design, Operation: For Flash, modify crossdomain.xml to use meta-policy options such as 'master-only' or 'none' to reduce the possibility of an attacker planting extraneous cross-domain policy files on a server.
