Password Manager: Improper Certificate Validation
CVE-2026-8497 is a high-severity improper certificate validation vulnerability in Password Manager from Devolutions, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 2026.2.2 as the first without the flaw, so updating Password Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.13% 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 Password Manager to 2026.2.2 or a later version.
- Read the advisory on devolutions.net for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
