metabase: Improper Neutralization of Argument Delimiters in a Command

Published Updated By the CyberSecBulletin desk

CVE-2026-50147 is a high-severity improper neutralization of argument delimiters in a command vulnerability in metabase, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. Affected metabase versions: >= 1.57.0, < 1.57.19.1; >= 1.58.0, < 1.58.14.1; >= 1.59.0, < 1.59.10, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Metabase is an open-source business intelligence and embedded analytics tool. From 1.57.0 until 1.57.19.1, 1.58.14.1, 1.59.10, and 1.60.4, an attacker who can configure a Metabase database connection can read arbitrary files from the Metabase server's filesystem by adding unsafe JDBC parameters to a MySQL or MariaDB connection, causing the driver to read files from the Metabase host and expose the contents through queries against the connected database or through validation error messages. This issue is fixed in versions 1.57.19.1, 1.58.14.1, 1.59.10, and 1.60.4.

The underlying weakness: Improper Neutralization of Argument Delimiters in a Command

The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.

How developers prevent this class of flaw

  • Understand all the potential areas where untrusted inputs can enter your product: parameters or arguments, cookies, anything read from the network, environment variables, request headers as well as content, URL components, e-mail, files, databases, and any external systems that provide data to the application. Perform input validation at well-defined interfaces.
  • Directly convert your input type into the expected data type, such as using a conversion function that translates a string into a number. After converting to the expected data type, ensure that the input's values fall within the expected range of allowable values and that multi-field consistencies are maintained.
  • When exchanging data between components, ensure that both components are using the same character encoding. Ensure that the proper encoding is applied at each interface. Explicitly set the encoding you are using whenever the protocol allows you to do so.
