      <title>CVE-2026-78122 — docker-socket-proxy through 0.5.0 Insufficient Access Control Granularity Exposes Container Filesystems</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-78122</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Tecnativa docker-socket-proxy&lt;/p&gt;
&lt;p&gt;docker-socket-proxy fails to properly gate read endpoints in the /containers Docker API namespace when the CONTAINERS environment variable is set. Attackers can use GET requests to /containers/{id}/archive, /containers/{id}/export, /containers/{id}/logs, and /containers/{id}/top to read arbitrary files and download entire container filesystems as tar archives.&lt;/p&gt;</description>
