CVE-2026-76898

draw.io is a configurable diagramming and whiteboarding application. Prior to version 30.3.8, src/main/java/com/mxgraph/online/Utils.java checks IPv6 Unique Local Addresses in Utils.sanitizeUrl by comparing the text prefixes fc00:: and fd00::, but the JDK returns the expanded address form, so the...

CVE-2026-76898

draw.io prior to version 30.3.8 is vulnerable to an unauthenticated SSRF via an IPv6 ULA blocklist bypass in /embed2.js. The root cause is in Utils.sanitizeUrl(), which checks for IPv6 ULA addresses by comparing the literal text prefixes fc00:: and fd00::, but the JDK returns the expanded address...

netty-handler: netty-handler: IPv6 subnet rule bypass due to incorrect masking operation

A flaw was found in netty-handler, a component of the Netty network application framework. A remote attacker can exploit an incorrect masking operation in the IpSubnetFilterRule.compareTo function to bypass configured IPv6 subnet rules. This allows valid public IP addresses to circumvent intended...
