cveClient/encrypt-storage.js: Insufficiently Protected Credentials
CVE-2026-35467 is a high-severity insufficiently protected credentials vulnerability in cveClient/encrypt-storage.js from CERT/CC, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.1.15 as the first without the flaw, so updating cveClient/encrypt-storage.js to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% 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 cveClient/encrypt-storage.js to 1.1.15 or a later version.
- Update Cveclient to 1.0.24 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
