Description

This security bulletin contains information about 1 vulnerability.


1) Missing Encryption of Sensitive Data (CVE-ID: N/A)

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to disclose sensitive information.

The vulnerability exists due to missing encryption of sensitive data in the ejson encryption walker when processing a specific nested JSON shape. A local user can encrypt a crafted file containing an array with an object whose final key begins with an underscore and a later sibling string value to disclose sensitive information.

The issue is silent because encryption and decryption use the same walker, so an affected file can round-trip without reporting the missing encryption.
