GHSA-H5G6-XMH4-HC37 OpenRun: Redirect URL validation bypass using  //host  paths leads to Open Redirect

Summary The restrictions on redirect URLs in openrun can be bypassed by attackers, leading to open redirect attacks. Details In the current project, the referrer header value is used for subsequent redirects, so there is currently a validation for this redirect value. The current validation logic...

CVE-2026-14198

The CVE-2026-14198 entry concerns @fastify/middie versions 9.1.0–9.3.2, where encoded slashes (%2F) in path parameter values are decoded by middie but not by Fastify’s router during route lookup. This mismatch lets a crafted URL bypass middleware-based security (authentication/authorization/rate ...

CVE-2026-10856

A URL validation flaw in the MISP dashboard button widget allowed a crafted relative-looking URL to be accepted as a local path while being interpreted by browsers as an external URL. The validation rejected URLs containing an explicit scheme, host, or user component, but did not reject paths...

Open Redirect

Overview Affected versions of this package are vulnerable to Open Redirect when certain URLs with path values starting with // are processed. An attacker can redirect users to external domains by supplying specially crafted protocol-relative URLs. Note: Users that utilise Declarative Mode are not...
