CVE-2026-63701 is a medium severity (CVSS 6.3) improper deserialization flaw in Dell Wyse Management Suite (WMS) before 2605.0.2. A low privileged attacker with local access could potentially escalate privileges. Dell advisory DSA-2026-329 covers it, and the fixed version is 2605.0.2.
What's affected
The record says Dell Wyse Management Suite versions prior to 2605.0.2. The record's description calls it an improper deserialization of untrusted data vulnerability, while the weakness it lists is CWE-269 (improper privilege management). Deserialization flaws are usually filed as CWE-502, so the two do not match; treat the description as the better guide to the mechanism.
The vector is local, high complexity, low privileges and no user interaction, with high confidentiality and integrity impact and no availability impact. The attacker needs a foothold on the host first.
The advisory is DSA-2026-329, which also covers CVE-2026-63700. Dell's support site requires a browser to view the advisory, so open the link in the sources and read the table of affected and remediated versions.
How to check if you're exposed
Find the installed WMS version on the management server.
Get-Package -Name "*Wyse Management*" | Select-Object Name, Version
Any version below 2605.0.2 is affected per the record. Also review accounts that can sign in to the host, since the attacker model begins with local access.
Whatever the product, a current inventory of what you run is what turns a CVE notice into a quick answer. The Gold page for this CVE tracks how its record changes over time, and the free in-browser dependency scan at gold.safeguard.sh/scan covers the application libraries you ship.
What to do now
- List every WMS server and its version.
- Update to 2605.0.2 or later, with a backup first.
- Patch together with CVE-2026-63700, which the same advisory covers.
- Limit local and remote desktop logins to administrators who need them.
- Monitor the host for new accounts or unexpected changes in local administrator membership.
Why it matters
Deserialization turns stored or transmitted bytes back into live objects. If the data comes from someone less trusted than the code reading it, the attacker may influence which objects are built and what they do. The result in this record is privilege escalation, not remote code execution.
The mismatch between the description and the weakness label is a reminder that vulnerability data is imperfect. When labels disagree, read the description and the vendor advisory. The record does not list the CVE as exploited in the wild.
Quick check
Why does the CWE not say deserialization?
The record lists the weakness as CWE-269, but its text describes deserialization of untrusted data. Records are sometimes labeled loosely, so rely on the vendor advisory for the mechanism.
