We generally recommend always updating Ghost to its most current version. \n\n### Workarounds\n\nThere is no application-level workaround. The Content API key is public by design, so restricting key access does not mitigate this vulnerability.\n\nAs 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.\n\n### References\n\nWe thank Nicholas Carlini using Claude, Anthropic for disclosing this vulnerability responsibly. \n\n### For more information\nIf you have any questions or comments about this advisory, email us at [security@ghost.org.","public_affected_ranges":[">= 3.24.0, < 6.19.1"]}],"null_published_at":"2026-11-07T07:07:39.849Z","source_updated_at":"2026-06-08T23:22:35.000Z","source_disclosed_at":"2026-02-18T21:50:23.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-07T00:51:53.608Z"}],"next_cursor":null,"snapshot_revision":"42594"}
