CVE-2026-41122 Dell CVE debrief

Who should care

Security teams and administrators responsible for Dell PowerProtect Data Domain systems should be aware of this vulnerability and take immediate action to mitigate the risk. This includes reviewing system deployments, applying vendor-provided patches or updates, and implementing compensating controls. The vulnerability's impact could lead to significant information disclosure, session theft, or client-side request forgery if exploited.

Technical summary

Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70, contain a stored cross-site scripting vulnerability. The vulnerability is exploitable by an unauthenticated attacker with remote access, potentially leading to information disclosure, session theft, or client-side request forgery. The vulnerability is caused by improper input validation, allowing an attacker to inject malicious scripts into the application.
