      <title>CVE-2026-53796 — rsync &lt; 3.5.0 TOCTOU Race Condition via Destination Directory Handling</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53796</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 time-of-check to time-of-use (TOCTOU) race condition vulnerability in the non-daemon receiver&amp;#39;s destination directory handling that allows an attacker who can manipulate destination path parent components to redirect file writes to unintended locations. Attackers can substitute a symlink for a component of the destination path between the path resolution and chdir() call, causing the receiver&amp;#39;s working directory to be established outside the intended destination tree so that subsequent relative-path file writes land in unintended filesystem locations.&lt;/p&gt;</description>
