ZITADEL, open source authentication management software, uses Go templates to render the login UI. Due to a improper use of the `text/template` instead of the `html/template` package, the Login UI did not sanitize input parameters prior to versions 2.47.3, 2.46.1, 2.45.1, 2.44.3, 2.43.9, 2.42.15, and 2.41.15. An attacker could create a malicious link, where he injected code which would be rendered as part of the login screen. While it was possible to inject HTML including JavaScript, the execution of such scripts would be prevented by the Content Security Policy. Versions 2.47.3, 2.46.1, 2.45.1, 2.44.3, 2.43.9, 2.42.15, and 2.41.15 contain a patch for this issue. No known workarounds are available.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.1, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), for affected systems. Impacting 1 product from zitadel organizations running these solutions should prioritize assessment and patching.
Reported in 2024, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For zitadel's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
