      <title>CVE-2026-54090 — File Browser: Command Allowlist Bypass via Shell Metacharacter Injection</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-54090</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; filebrowser&lt;/p&gt;
&lt;p&gt;File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.33.8, when a shell interpreter is configured (e.g. /bin/sh -c), the command allowlist can be bypassed through shell metacharacters. The allowlist validates only the first token of user input, but the entire raw string is handed to the shell — semicolons, pipes, backticks, and $() all work to chain arbitrary commands after a permitted one. This vulnerability is fixed in 2.33.8.&lt;/p&gt;</description>
