DEBIAN-CVE-2025-65110
No affected components available
Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs. Prior to versions 6.1.2 and 5.6.3, applications meeting two conditions are at risk of arbitrary JavaScript code execution, even if "safe mode" expressionInterpreter is used. First, they use vega in an application that attaches both vega library and a vega.View instance similar to the Vega Editor to the global window, or has any other satisfactory function gadgets in the global scope. Second, they allow user-defined Vega JSON definitions (vs JSON that was is only provided through source code). This vulnerability allows for DOM XSS, potentially stored, potentially reflected, depending on how the library is being used. The vulnerability requires user interaction with the page to trigger. An attacker can exploit this issue by tricking a user into opening a malicious Vega specification. Successful exploitation allows the attacker to execute arbitrary JavaScript in the context of the application’s domain. This can lead to theft of sensitive information such as authentication tokens, manipulation of data displayed to the user, or execution of unauthorized actions on behalf of the victim. This exploit compromises confidentiality and integrity of impacted applications.Patched versions are available in vega-selections@6.1.2 (requires ESM) for Vega v6 and vega-selections@5.6.3 (no ESM needed) for Vega v5. As a workaround, do not attach vega or vega.View instances to global variables or the window as the editor used to do. This is a development-only debugging practice that should not be used in any situation where Vega/Vega-lite definitions can come from untrusted parties.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data.
