CVE-2025-57348

The node-cube package (prior to version 5.0.0) contains a vulnerability in its handling of prototype chain initialization, which could allow an attacker to inject properties into the prototype of built-in objects. This issue, categorized under CWE-1321, arises from improper validation of user-supplied input in the package's resource initialization process. Successful exploitation may lead to denial of service or arbitrary code execution in affected environments. The vulnerability affects versions up to and including 5.0.0-beta.19, and no official fix has been released to date.

Base score	Version	Severity	Vector	Exploitability	Impact	Score source
6.5	3.1	MEDIUM	`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L` Click to expand Attack vector (AV:N) Could be attacked over the internet or any normal routed network—not just someone sitting at the machine. Attack complexity (AC:L) Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup. Privileges required (PR:N) No account or special rights needed—anonymous or random user is enough. User interaction (UI:N) Nobody has to click “OK” or open a trap file; it can work without a victim helping. Scope (S:U) Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems. Confidentiality (C:L) Some sensitive info could get out, but not a total data dump. Integrity (I:N) Data isn’t meaningfully altered or forged. Availability (A:L) Might cause slowdowns, glitches, or partial disruption—not a full brick.	3.9	2.5	134c704f-9b21-4f2e-91b3-4a467353bcc0
