ObjectScale: Use of Default Credentials

CVE-2026-22273 is a high-severity use of default credentials vulnerability in ObjectScale from Dell, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 4.2.0.0 as the first without the flaw, so updating ObjectScale to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.

The underlying weakness: Use of Default Credentials

The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality.

How developers prevent this class of flaw

  • Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
  • Force the administrator to change the credential upon installation.
  • The product administrator could change the defaults upon installation or during operation.
