CVE-2026-1212888.1 HIG14.8%
——4An unauthenticated attacker on an adjacent network segment can bypass MD5 authentication and have unauthorized RIP route updates accepted by the device. Successful exploitation requires that RIPv2 MD5 authentication is configured on the affected interface. An attacker who can inject crafted RIPv2 packets could cause the device to install routes that redirect network traffic through attacker-controlled paths, create routing loops, or blackhole traffic, disrupting network connectivity.1dCVE-2026-964605.4 MED15.3%
——5A flaw was found in the token exchange mechanism of Keycloak. When using Standard Token Exchange V2, the system issues new tokens with a fresh lifetime based on the requester clients configuration instead of limiting it to the original tokens expiration. This issue allows an authenticated requester to indefinitely extend access for service accounts by repeatedly exchanging tokens, even if the original client has been disabled by an administrator.2dCVE-2026-1099287.4 HIG32.7%
——10Incorrect Implementation of Authentication Algorithm in the password-reset and login JWT validation in Apache OFBiz 24.09 before 24.09.08 on all platforms allows an attacker who has obtained a user's password-reset token (via email interception, log exposure, or a man-in-the-middle on the mail transport) to authenticate as that user and obtain a full, unrestricted session, including administrative access if the targeted account is an administrator, by submitting the token directly to the login endpoint instead of the intended password-change flow. Users are recommended to upgrade to version 24.09.08, which fixes this issue.1dCVE-2026-842966.8 MED27.6%
——8Multi-Factor Authentication Bypass vulnerability in SSH component in Progress Software WS_FTP Server versions prior to 2024.0.6, and 2025.0.3 on Windows allows authenticated users to bypass MFA requirements through improper association of authentication factors between accounts.12dCVE-2026-865895.4 MED17.0%
——5Incorrect implementation of authentication algorithm vulnerability in Apache Answer.
This issue affects Apache Answer: through 2.0.2.
A flaw in the User Center login integration can cause a newly created external user session to omit its external identity, allowing subsequent requests to bypass central account suspension or deletion checks until the session
expires or is revoked.
Users are recommended to upgrade to version 2.0.3, which fixes the issue.12dCVE-2026-890777.5 HIG40.6%
——12Incorrect implementation of authentication algorithm vulnerability in Progress MOVEit Transfer (SFTP module).
This issue affects MOVEit Transfer: before 2025.1.6 and from 2026.0.0 before 2026.0.4.24d
