Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Timely identification, reporting, and patching of the SSRF flaw in Tableau Server versions 2023.3 through 2023.3.5 directly prevents authentication bypass exploitation as advised by Salesforce.

SI-10 Information Input Validation good match

prevent

Validates information inputs such as URLs or parameters to the Tableau Server to block malicious SSRF requests that enable authentication bypass.

AC-4 Information Flow Enforcement partial match

prevent

Enforces approved information flow control policies to restrict unauthorized server-side requests to internal authentication endpoints via SSRF.

Server-Side Request Forgery (SSRF) vulnerability in Salesforce Tableau Server allows Authentication Bypass.This issue affects Tableau Server: from 2023.3 through 2023.3.5.

Deeper analysisAI

CVE-2025-26494 is a Server-Side Request Forgery (SSRF) vulnerability, classified as CWE-918, in Salesforce Tableau Server that allows authentication bypass. It affects Tableau Server versions from 2023.3 through 2023.3.5. The vulnerability carries a CVSS v3.1 base score of 7.7 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) and was published on 2025-02-11T18:15:47.060.

An attacker requires low privileges (PR:L) to exploit this issue over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation changes scope (S:C) and results in high confidentiality impact (C:H) with no impact on integrity or availability, enabling authentication bypass via SSRF.
