      <title>CVE-2026-53791 — rsync &lt; 3.5.0 Daemon IP Spoofing via PROXY Protocol Header</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53791</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; RsyncProject rsync&lt;/p&gt;
&lt;p&gt;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 spoofed source IP in the PROXY protocol header to circumvent hosts allow/deny rules, gaining unauthorized access that would otherwise be blocked based on their real source address.&lt;/p&gt;</description>
