PowerProtect Data Manager: Generation of Incorrect Security Tokens
CVE-2026-49499 is a high-severity generation of incorrect security tokens vulnerability in PowerProtect Data Manager 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 20.2.0.0 or later as the first without the flaw, so updating PowerProtect Data Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.42% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

The underlying weakness: Generation of Incorrect Security Tokens

How developers prevent this class of flaw
- Generation of Security Tokens should be reviewed for design inconsistency and common weaknesses. Security-Token definition and programming flow should be tested in pre-silicon and post-silicon testing.
