metabase: External Control of File Name or Path
CVE-2026-50148 is a critical-severity external control of file name or path vulnerability in metabase, with a CVSS 3.1 base score of 9.1 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: >= 1.54.0, < 1.54.24; >= 1.55.0, < 1.55.24; >= 1.56.0, < 1.56.25, 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 0.77% chance of exploitation within 30 days, higher than 56% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of metabase you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.

Official description
Metabase is an open-source business intelligence and embedded analytics tool. From 1.54.0 until 1.54.24, 1.55.24, 1.56.25, 1.57.19, 1.58.14, 1.59.10, and 1.60.4, a Metabase user with permission to add or edit a database connection can achieve remote code execution on the Metabase server by configuring a Snowflake connection to an attacker-controlled server, because a flaw in the Snowflake JDBC driver can write arbitrary files anywhere on the Metabase host, including replacing one of Metabase's own database driver files that later executes inside the Metabase process. This issue is fixed in versions 1.54.24, 1.55.24, 1.56.25, 1.57.19, 1.58.14, 1.59.10, and 1.60.4.

The underlying weakness: External Control of File Name or Path
The product allows user input to control or influence paths or file names that are used in filesystem operations.
How developers prevent this class of flaw
- When the set of filenames is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames, and reject all other inputs. For example, ID 1 could map to inbox.txt and ID 2 could map to profile.txt. Features such as the ESAPI AccessReferenceMap provide this capability.
- Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict all access to files within a particular directory. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
