GitHub AdvisoriesGHSA-w52v-v783-gw97 9.4

Ghost has a SQL injection in Content API

Impact

A SQL injection vulnerability existed in Ghost's Content API that allowed unauthenticated attackers to read arbitrary data from the database.

Vulnerable Versions

This vulnerability is present in Ghost v3.24.0 to v6.19.0.

Patches

v6.19.1 contains a fix for this issue.

Note: as this vulnerability lets an attacker gain access to a site's API keys, we recommend reviewing staff users and rotating keys. We generally recommend always updating Ghost to its most current version.

Workarounds

There is no application-level workaround. The Content API key is public by design, so restricting key access does not mitigate this vulnerability.

As a temporary mitigation, a reverse proxy or WAF rule can be used to block Content API requests containing slug%3A%5B or slug:[ in the query string filter parameter. Note that this may break legitimate slug filter functionality.
