CVE-2026-77317

CVE-2026-77317 affects SeaweedFS (distributed file/blob storage system) versions 3.88 through 4.39. The SFTP server evaluates configured path permissions using a literal string-prefix comparison rather than requiring a path-component boundary. A user scoped to a path such as /tenants/alice is als...

CVE-2026-19538

A flaw was found in nsd. A remote attacker can bypass BLOCKED access control list ACL items on the proxy protocol port. This bypass occurs when connecting over TCP or TLS and sending the query twice on a persistent connection. This could allow unauthorized access or actions that should have been...

CVE-2026-18664

A flaw was found in NSD. On systems using little-endian architecture, the software incorrectly compares IP addresses against defined Access Control List ACL ranges. This misinterpretation can lead to a bypass of intended access controls, where IP addresses that should be denied access are instead...

CVE-2026-18664 Wrong interpretation of ACL ranges

When ranges are used for access control i.e. of the form 1.2.3.4-1.2.3.25, because NSD wrongly compares the IP address with the range on little endian systems, IPs that were meant to be allowed may be denied, and, IPs that were meant to be denied access could be allowed. An IPv4 address is compar...

CVE-2026-18664

NSD (a DNS server maintained by NLnet Labs) contains a flaw in its ACL range comparison logic. On little-endian systems , IP addresses are compared using the host's native endianness instead of network byte order (big-endian) , which is the correct format for the stored values. This affects both ...
