      <title>CVE-2026-34955 — PraisonAI: Sandbox Escape via shell=True and Bypassable Blocklist in SubprocessSandbox</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-34955</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; MervinPraison PraisonAI&lt;/p&gt;
&lt;p&gt;PraisonAI is a multi-agent teams system. Prior to version 4.5.97, SubprocessSandbox in all modes (BASIC, STRICT, NETWORK_ISOLATED) calls subprocess.run() with shell=True and relies solely on string-pattern matching to block dangerous commands. The blocklist does not include sh or bash as standalone executables, allowing trivial sandbox escape in STRICT mode via sh -c &amp;#39;&amp;lt;command&amp;gt;&amp;#39;. This issue has been patched in version 4.5.97.&lt;/p&gt;</description>
