CVE-2026-23775 Dell CVE debrief

Dell PowerProtect Data Domain appliances with Data Domain Operating System (DD OS) Feature Release versions 8.0 through 8.5 and LTS2025 release version 8.3.1.0 through 8.3.1.10 are vulnerable to an insertion of sensitive information into log file vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to credential exposures. However, authentication attempts as the compromised user would need to be authorized by a high privileged DD user. This vulnerability only affects systems with retention lock enabled.
