Name of the Vulnerable Software and Affected Versions
safeurl versions prior to 0.2.4
Description
The
privateNetworks blocklist fails to include several newly added IPv6 CIDR ranges, specifically 64:ff9b:1::/48 (NAT64 local-use prefix), 5f00::/16 (Segment Routing SIDs), 3fff::/20 (documentation prefix), and 100:0:0:1::/64 (Dummy IPv6 Prefix). This omission could allow an attacker to reach resources hosted on IP addresses within these missing ranges.Recommendations
Upgrade to version 0.2.4.
As a temporary workaround, disable IPv6 by setting
EnableIPv6(false). Found an issue in the description? Have something to add? Feel free to write us 👾
