CVE-2024-28255
Published: April 11, 2026
Official Description
OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. The `JwtFilter` handles the API authentication by requiring and verifying JWT tokens. When a new request comes in, the request's path is checked against this list. When the request's path contains any of the excluded endpoints the filter returns without validating the JWT. Unfortunately, an attacker may use Path Parameters to make any path contain any arbitrary strings. For example, a request to `GET /api/v1;v1%2fusers%2flogin/events/subscriptions/validation/condition/111` will match the excluded endpoint condition and therefore will be processed with no JWT validation allowing an attacker to bypass the authentication mechanism and reach any arbitrary endpoint, including the ones listed above that lead to arbitrary SpEL expression injection. This bypass will not work when the endpoint uses the `SecurityContext.getUserPrincipal()` since it will return `null` and will throw an NPE.
Technical Analysis
CVE-2024-28255 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-28255 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
