Not enough EPSS history yet.
On affected platforms running Arista EOS with authenticated Bidirectional Forwarding Detection (BFD) sessions configured, a specially crafted packet can cause the BFD session(s) to go down. This may result in undesirable network changes because various routing protocols monitor status on BFD session(s).

CVE-2026-734444.7 MED—
———On affected platforms running Arista EOS with VRRPv2 IP Authentication Header (IP-AH) authentication configured, an unauthenticated attacker with access to the layer 2 network segment on which VRRP is running could bypass VRRP authentication and claim the virtual router master role, enabling the attacker to intercept, modify, or discard traffic that hosts on the segment send to the virtual gateway address.3hCVE-2026-3869—44.1%
——13CWE-303 : Incorrect Implementation of Authentication Algorithm vulnerability exists that could cause loss of confidentiality, integrity and availability of the PLC provided an application project with a lower application level is running on the PLC.5dCVE-2026-786295.6 MED0.9%
——0The Okta Hyperdrive agent plugin returns a success response without a signed SAML assertion when the organization's policy requires no MFA for a given user. The response contains only a bare boolean validation indicator with no cryptographic artifact, resulting in an unverifiable authentication verdict being delivered to the relying application.6dCVE-2026-9854—2.6%
——1A vulnerability exists in SYS600 RBAC mechanism where users having access to the engineering tools could elevate their privileges to administrator level on the underlying Windows host, granting themselves full control over the host machine.13dCVE-2026-9853—2.6%
——1A vulnerability exists in SYS600 which allows any user authenticated to the operating system of the server hosting the application to read and modify application objects without being authenticated to the SYS600 system itself.
Only the SYS600 system users should be permitted to view and modify application objects.13dCVE-2026-494678.8 HIG34.7%
——10Pingvin Share X is a secure and easy self-hosted file sharing platform. A vulnerability in versions 1.5.0 through 1.18.0 allow an attacker to bypass password verification when managing Time-based One-Time Password (TOTP) settings. The root cause is a missing `await` keyword on calls to the asynchronous `verifyPassword` method in `authTotp.service.ts` and the `authenticateUser` method in `auth.service.ts`. In JavaScript, an unawaited `Promise` is always truthy. So the logic intended to throw a `ForbiddenException` when a password is incorrect. It never executes because the expression evaluates the existence of the `Promise` object rather than its resolved boolean result. The vulnerability is fixed in version 1.18.1 by ensuring all asynchronous authentication calls are properly awaited. There are no official workarounds. If a user is locked out, an administrator must manually reset the user's TOTP status in the database.7d
