KNIME Business Hub: Improper Neutralization of Input During Web Page Generation
CVE-2025-3019 is a high-severity improper neutralization of input during web page generation vulnerability in KNIME Business Hub from KNIME, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 1.13.3, 1.12.4 as the first without the flaw, so updating KNIME Business Hub to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% 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 KNIME Business Hub to 1.13.3 or 1.12.4, whichever matches your release line, or a later version.
- Update Business Hub to 1.12.4 or 1.13.3, whichever matches your release line, or a later version.
- Read the advisory on knime.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
KNIME Business Hub is affected by several cross-site scripting vulnerabilities in its web pages. If a user clicks on a malicious link or opens a malicious web page, arbitrary Java Script may be executed with this user's permissions. This can lead to information loss and/or modification of existing data. The issues are caused by a bug https://github.com/Baroshem/nuxt-security/issues/610 in the widely used nuxt-security module. There are no viable workarounds therefore we strongly recommend to update to one of the following versions of KNIME Business Hub: * 1.13.3 or later * 1.12.4 or later

The underlying weakness: Improper Neutralization of Input During Web Page Generation
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
- Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
- 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.
