Salesforce disclosed a set of critical vulnerabilities in Tableau Server affecting Windows and Linux deployments, with the most serious bugs enabling remote code execution, arbitrary file access, and unauthorized access to backend data. Reported issues include CVE-2025-52449 for dangerous file uploads that can lead to code execution, CVE-2025-52451 for path traversal in the tabdoc API that can expose arbitrary files readable by the Tableau process, and CVE-2025-52448 for authorization bypass in the validate-initial-sql API. A related high-severity flaw, CVE-2025-52446, also allows authorization bypass through user-controlled keys in tab-doc API modules.
The affected releases include Tableau Server versions prior to 2025.1.3, 2024.2.12, and 2023.3.19, and Salesforce urged customers to install the latest maintenance releases and update Trino drivers where applicable. Separate reporting also identified CVE-2025-26496, a critical type confusion flaw in Tableau Server and Tableau Desktop file upload functionality that could allow arbitrary code execution within the Tableau application context, reinforcing concerns about recurring weaknesses in file handling, input validation, and access control across the Tableau product line.

Grafana issued urgent patches for two high-severity vulnerabilities, including **`CVE-2026-27876`**, a critical flaw in the SQL Expressions feature that can allow an attacker with **Viewer** privileges or higher to write arbitrary files to the server and potentially escalate to full **remote code execution**. The issue can be chained into broader compromise scenarios, including unauthorized SSH access, prompting public warnings from national defenders such as Belgium’s CCB to patch immediately. Grafana also fixed **`CVE-2026-27880`**, which affects OpenFeature validation endpoints and allows **unauthenticated** attackers to crash vulnerable instances by sending oversized requests that exhaust memory. Grafana Labs said patched releases, including **12.4.2**, are available and noted that **Amazon Managed Grafana** and **Azure Managed Grafana** were already protected under embargo; for temporary mitigation, administrators were advised to disable the `sqlExpressions` feature toggle and use highly available deployments and reverse proxies such as **Nginx** or **Cloudflare** to restrict request sizes.

Splunk issued urgent fixes for **CVE-2026-20253**, a critical `CVSS 9.8` vulnerability in **Splunk Enterprise** that allows unauthenticated arbitrary file creation and truncation through a PostgreSQL sidecar service endpoint missing authentication controls. The flaw affects supported Splunk Enterprise releases prior to **10.4.0**, **10.2.4**, **10.0.7**, **9.4.12**, and **9.3.13** depending on branch, and Splunk said **Splunk Cloud is not affected** because it does not use Postgres sidecars. Splunk and national cyber authorities urged administrators to apply updates immediately, noting that no vendor detections or workarounds were initially available for the core issue. Public technical analysis from watchTowr Labs showed the bug can be reached through Splunk Web on port `8000`, which proxies requests to localhost-only PostgreSQL recovery endpoints, enabling attackers to abuse `/v1/postgres/recovery/backup` and `/restore` for filesystem access. Researchers demonstrated a full pre-auth exploitation chain that used path traversal, PostgreSQL connection-string injection, local `.pgpass` credentials, and PostgreSQL large-object export to gain arbitrary file write as the `splunk` user, then overwrite a Splunk Python script to achieve remote code execution. Splunk also disclosed additional Enterprise flaws including **CVE-2026-20251** (`CVSS 8.8`) in the Splunk Secure Gateway app due to unsafe `jsonpickle` deserialization, plus stored XSS and SSRF issues, prompting guidance to patch quickly, restrict dashboard creation and web exposure, and disable or remove vulnerable components where immediate upgrades are not possible.

SAP released security updates for 17 vulnerabilities across its product portfolio, including two critical flaws led by **CVE-2024-41730** in **SAP BusinessObjects Business Intelligence Platform**. The vulnerability carries a `CVSS 9.8` rating and can allow a remote, unauthenticated attacker to take full control of an affected system through the REST interface when **SSO** is enabled. The issue is tracked in the CVE program and was highlighted alongside broad remediation guidance urging customers to apply the latest patches immediately. SAP also fixed **CVE-2024-29415** in **SAP Build Apps**, a `CVSS 9.1` server-side request forgery flaw tied to a Node.js component that improperly distinguishes public and private IP addresses. Additional patched issues across SAP products could enable code execution, cross-site scripting, SSRF, XML injection, privilege escalation, denial of service, unauthorized access to sensitive data, and authentication bypass, underscoring the risk to internet-exposed and enterprise SAP environments.
