      <title>CVE-2026-53799 — rsync &lt; 3.5.0 Symlink Race Condition via ACL/xattr Application</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-53799</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; RsyncProject rsync&lt;/p&gt;
&lt;p&gt;rsync before 3.5.0 contains a symlink race condition vulnerability that allows local attackers to cause rsync to apply arbitrary ACLs or extended attributes to unintended files by substituting a symlink at a predictable destination path between the file write and the subsequent acl_set_file() or lsetxattr() call. Attackers can exploit this timing window to redirect ACL and xattr application through a crafted symlink to files outside the intended destination tree, potentially granting elevated permissions and enabling local privilege escalation.&lt;/p&gt;</description>
