Zitadel

Zitadel is an open-source identity and access management platform that, despite a narrowly focused product portfolio, occupies a prominent position in the authentication and authorization infrastructure landscape. Vulnerabilities affecting the vendor skew toward serious outcomes, with a meaningful share reaching critical severity, and recur across its core IAM offering through weakness classes centered on improper input neutralization and cross-site scripting, authorization flaws, authentication bypass conditions, and exposure of sensitive credentials or session data. These vulnerability classes reflect the inherent complexity of identity systems: the handling of user input, token generation, permission evaluation, and credential storage across web-facing endpoints. Defenders deploying Zitadel as a centralized authentication service should prioritize this vendor's advisories, since flaws in IAM logic or web-layer protections can compromise access to downstream applications. Current exploitation activity, severity distribution, and remediation urgency are shown alongside this summary.
