PowerProtect Data Domain Virtual Edition: Path Traversal: 'dir....filename'
CVE-2026-94346 is a high-severity path traversal: 'dir....filename' vulnerability in PowerProtect Data Domain Virtual Edition from Dell, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions 8.9.0.0 or later, 7.13.1.80 or later, 8.3.1.40 or later as the first without the flaw, so updating PowerProtect Data Domain Virtual Edition to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.53% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PowerProtect Data Domain Virtual Edition to 8.9.0.0 or later or 7.13.1.80 or later or 8.3.1.40 or later or 8.6.1.20 or later, whichever matches your release line, or a later version.

The underlying weakness: Path Traversal: 'dir....filename'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize 'dir....filename' (multiple internal backslash dot dot) sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
