      <title>CVE-2026-50548 — Cursor Desktop sandbox escape via agent-controlled working directory</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-50548</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; cursor&lt;/p&gt;
&lt;p&gt;Cursor is a code editor built for programming with AI. Prior to 3.0, Cursor runs agent terminal commands in a sandbox by default, and the sandbox grants write access to the command&amp;#39;s working directory. A flaw was identified in how the agent could modify the working_directory parameter, which could cause the sandbox to include writable paths outside the intended workspace. A malicious agent could set working_directory to a sensitive location and write arbitrary files outside the workspace under the user&amp;#39;s privileges. This enables non-sandboxed Remote Code Execution — for example by overwriting the cursorsandbox helper so later commands run unsandboxed — with no user interaction beyond a benign prompt. This vulnerability is fixed in 3.0.&lt;/p&gt;</description>
