CVE-2023-3615
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
The Mattermost iOS app fails to properly validate the server certificate while initializing the TLS connection, allowing a network attacker to intercept the WebSockets connection.
Risk Assessment
The lack of proper server certificate validation poses a risk of data interception by an attacker, potentially leading to the exposure of sensitive information.
Recommendation
It is recommended to update the Mattermost app to the latest version that improves server certificate validation and to implement additional security measures to protect TLS connections.

Kiteworks Email Protection Gateway did not sufficiently restrict which account a certificate could be assigned to. This could allow an attacker to associate a certificate with another user's account, affecting the confidentiality and integrity of that account's encrypted mail and, where certificate-based login is enabled, potentially permitting unauthorized access to the account.
- CVE-2026-102147Critical
A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an unauthenticated attacker to store crafted content that later executes arbitrary JavaScript in the authenticated session of an administrator who views the affected page. This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.
