CVE-2026-57216
A flaw was found in RabbitMQ, a messaging and streaming broker. The AMQP 0-9-1, AMQP 1.0, and Stream Protocol authentication mechanisms incorrectly perform a loopback check. This allows a user, typically restricted to loopback connections such as a guest user, to connect remotely. This occurs whe...
CVE-2026-53791
A flaw in rsync allows an unauthenticated remote attacker to bypass IP-based access controls by sending a crafted PROXY protocol header with a forged source IP address, granting unauthorized access to restricted resources. Mitigation Restrict rsync daemon TCP/873 to the trusted proxy only CME-202...
SUSE CVE-2026-53791
rsync daemon before 3.5.0 contains an IP address spoofing vulnerability that allows unauthenticated remote attackers to bypass IP-based access controls by sending a crafted PROXY protocol header with a forged source address. Attackers who can connect directly to the rsync daemon can inject a...
BIT-PROXYSQL-2026-48772 ProxySQL: PROXY-Protocol-v1 UNKNOWN parses spoofed source IP, bypassing mysql_query_rules.client_addr ACL
ProxySQL is a proxy for MySQL and its forks, as well as PostgreSQL. In versions 2.0.0 through 3.0.8, the ProxySQL MySQL frontend accepts the PROXY UNKNOWN \r\n PP1 frame as a well-formed PROXY protocol header. The HAProxy PROXY protocol v1 specification says that when the protocol token is UNKNOW...
BIT-MONGODB-2026-13067 tlsCATrusts Role Restriction Not Enforced via PROXY Protocol v2 on Unix Domain Socket
When PROXY protocol v2 is used on the Unix domain socket path, roles derived from X.509 client certificates may not be validated against the configured tlsCATrusts allow-list. This can result in unintended role assignments following MONGODB-X509 authentication. Affected scenarios require local...
