Tableau Server: Unrestricted Upload of File with Dangerous Type
CVE-2025-52449 is a high-severity unrestricted upload of file with dangerous type vulnerability in Tableau Server from Salesforce, with a CVSS 3.1 base score of 8.5 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists versions 2025.1.3, 2024.2.12, 2023.3.19 as the first without the flaw, so updating Tableau Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Tableau Server to 2025.1.3 or 2024.2.12 or 2023.3.19, whichever matches your release line, or a later version.
- Read the advisory on help.salesforce.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Unrestricted Upload of File with Dangerous Type
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
How developers prevent this class of flaw
- Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
