CVE-2026-93690

A flaw was found in uri-js. A remote attacker can exploit a vulnerability in the removeDotSegments function by providing a specially crafted path segment that begins with Unicode line or paragraph separators. This can cause an infinite loop, leading to the Node.js event loop blocking indefinitely and resulting in a denial of service (DoS) for applications using the component.

Red Hat rates the impact of this vulnerability as Important because an unauthenticated remote attacker can cause a complete denial of service across exposed services without requiring any privileges. In Red Hat environments where containerized services or web management consoles process user-supplied URI input, malformed Unicode separator characters can induce an unconstrained processing loop. This condition halts the execution loop in server-side JavaScript runtimes, rendering affected web interfaces or API endpoints completely unresponsive to legitimate user traffic until the process is restarted.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
