Description

All CVEs covered in this advisory affect CloudVision Portal (On-Premises), where specially crafted requests could result in user redirection to arbitrary URLs.

The below issues were discovered internally by Arista, and the company is not aware of any malicious exploitation of these vulnerabilities in customer deployments.

CVE-2026-101151

Insufficient validation of request in login flow could allow a remote, unauthenticated attacker to craft a URL that, when clicked by a user, redirects the user's browser to an arbitrary external site upon completion of the authentication process.
CVSSv3.1 Base Score: 4.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)
CVSSv4.0 Base Score: 5.3 (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N)
Common Weakness Enumeration: CWE-601: URL Redirection to Untrusted Site ('Open Redirect')
This vulnerability is being tracked by BUG 1612748

CVE-2026-101152

Insufficient validation in the Single Sign-On (SSO) login flow could allow a remote, unauthenticated attacker to craft a URL that, when clicked by a user, causes the identity provider (IdP) to deliver authentication material to an attacker-controlled URL instead of to CloudVision.
CVSSv3.1 Base Score: 8.0 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N)
CVSSv4.0 Base Score: 7.6 (CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N)
Common Weakness Enumeration:CWE-601: URL Redirection to Untrusted Site ('Open Redirect')

Required Configuration for Exploitation

 

CVE-2026-101151

No specific configuration is required to be vulnerable to this issue. This vulnerability is present in the default configuration of affected CloudVision releases.

CVE-2026-101152

In order to be vulnerable to CVE-2026-101152, SSO must be configured with an external identity provider. Deployments using only non-SSO authentication are not affected.

To check if SSO is configured, navigate to Settings → Authentication in the CloudVision UI. If an OIDC or SAML provider is configured, the deployment is potentially affected.
