Security Advisory 0186 .CSAF PDF

Date: October 6, 2026

Revision Date Changes
1.0 October 6, 2026 Initial release

Description

All CVEs covered in this advisory affect platforms running CloudVision Portal (on-premises) where OpenID Connect (OIDC)-based single sign-on (SSO) is configured with an identity provider. OIDC SSO is an optional, explicitly configured authentication method. Deployments using non-OIDC SSO methods are not affected.

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-2026-101149

Insufficient validation of OIDC SSO provider configuration could allow a user with specific high privileges to direct requests to arbitrary destinations.
CVSSv3.1 Base Score: 4.1 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N)
CVSSv4.0 Base Score: 5.1 (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N)
Common Weakness Enumeration: CWE-918: Server-Side Request Forgery (SSRF)
This vulnerability is being tracked by BUG 1919444

CVE-2026-101150

Insufficient validation of OIDC bearer token configuration could allow a user with specific high privileges to direct requests to arbitrary destinations.
CVSSv3.1 Base Score: 4.1 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N)
CVSSv4.0 Base Score: 5.1 (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N)
Common Weakness Enumeration: CWE-918: Server-Side Request Forgery (SSRF)
This vulnerability is being tracked by BUG 1919438

Required Configuration for Exploitation

Both CVEs require that an OIDC identity provider has been configured.

CVE-2026-101149

In order to be vulnerable to CVE-2026-101149, OAuth SSO must be configured.

To verify, navigate to Settings → Access Management → Authentication → SSO Providers. If any provider appears under the OAuth Providers section, OAuth SSO is configured. If no provider is listed, there is no exposure to this issue.

CVE-2026-101150

In order to be vulnerable to CVE-2026-101150, OAuth SSO must be configured (see Fig 1 above), and Allow Bearer Token Login must be enabled in cluster management settings.

To verify, navigate to General Settings  → Cluster Management. If the “Allow Bearer Token Login” toggle is disabled, there is no exposure to this issue.

Indicators of Compromise

No indicators of compromise exist for both the issues.

Mitigation

There is no configuration-based mitigation for these issues. However, operators can look into switching to an alternative non-OIDC SSO login method, if feasible.

Additionally, restrict AAA settings & Account Management configuration permissions to trusted personnel only.

To do this, navigate to Settings → Roles, then click on the "Pencil" icon beside a role to edit it.

Ensure that only administrative roles have “Read and Write” permission on AAA Settings and Account and Session Management

Then, go to Settings → Users. Ensure that only trusted personnel have administrative roles.
