rsync: rsync: Authorization bypass via `auth users` directive parsing

An authorization bypass flaw was found in the rsync daemon. The auth users directive parser incorrectly handles group names containing spaces due to comma-only tokenization. This flaw causes deny rules to be silently discarded, allowing an authenticated user to bypass restrictions and gain...

EUVD-2026-77448

File Browser through 2.63.23 applies path rules to the requested lexical path but resolves symbolic links without reapplying rules to the target, allowing authenticated users to bypass deny rules. Attackers can read and overwrite rule-denied files by accessing them through in-scope symbolic link...

CVE-2026-58209

A flaw was found in NATS Server. This vulnerability allows for unauthorized information disclosure where MQTT messages, intended to be denied based on subscription rules, are still delivered to subscribers. This occurs because the server's delivery paths do not consistently recheck the original...

CVE-2026-70452

A flaw was found in rsync. This vulnerability allows a remote attacker to bypass hostname-based access control rules. By inducing DNS resolution failures, the rsync daemon incorrectly skips deny rules, granting unauthorized access to restricted module file trees. Mitigation To mitigate this issue...

CVE-2026-63743

SurrealDB prior to 3.1.0 contains a capability bypass in HTTP redirect handling that enables an authenticated user to circumvent port-scoped --deny-net rules. An attacker can chain an HTTP redirect from an allowed hostname to a denied host:port combination, and the redirect is followed because po...

SUSE CVE-2026-58251

NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, an authenticated user with subscription deny permissions could bypass a plain subject deny rule by using a queue subscription, because queue-specific deny...

CVE-2026-58252

A flaw was found in NATS Server. An authenticated user could bypass configured access restrictions and receive messages on subjects that were explicitly denied. This occurs when a wildcard subscription overlaps with a wildcard deny rule but is not a direct subset, or when queue subscriptions...
