CVE-2024-49753 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2024-49753 Interim 1 13 2026-03-05T02:00:24Z current 2024-11-02T00:13:29Z 2026-03-05T02:00:24Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2024-49753 Zitadel is open-source identity infrastructure software. Versions prior to 2.64.1, 2.63.6, 2.62.8, 2.61.4, 2.60.4, 2.59.5, and 2.58.7 have a flaw in the URL validation mechanism of Zitadel actions allows bypassing restrictions intended to block requests to localhost (127.0.0.1). The isHostBlocked check, designed to prevent such requests, can be circumvented by creating a DNS record that resolves to 127.0.0.1. This enables actions to send requests to localhost despite the intended security measures. This vulnerability potentially allows unauthorized access to unsecured internal endpoints, which may contain sensitive information or functionalities. Versions 2.64.1, 2.63.6, 2.62.8, 2.61.4, 2.60.4, 2.59.5, and 2.58.7 contain a patch. No known workarounds are available.
