SAP released its June Security Patch Day updates to fix multiple vulnerabilities across products including SAP NetWeaver AS ABAP, ABAP Platform, SAP NetWeaver Application Server Java, SAP Commerce Cloud, SAP Data Hub, SAP S/4HANA, SAP Business Objects Business Intelligence Platform, and SAP Fiori launchpad. The issues could allow cross-site scripting, denial of service, email spoofing, sensitive information disclosure, privilege escalation, data manipulation, arbitrary code execution, and unauthorized access.
The most severe flaws include CVE-2026-44748, an XML Signature Wrapping weakness in SAML authentication affecting SAP NetWeaver AS ABAP and ABAP Platform with a CVSS 9.9, and CVE-2026-40128, a directory traversal vulnerability in the SAP NetWeaver Application Server Java Web Container rated CVSS 9.0. EG-FinCIRT said organizations should apply the patches as soon as testing is complete to reduce exposure across affected SAP environments.

SAP released 15 new security notes to fix vulnerabilities across major product lines, with four critical issues demanding immediate attention in **SAP NetWeaver**, **SAP Commerce Cloud**, and **SAP Data Hub**. The most severe flaw, **`CVE-2026-44748`** (CVSS 9.9), is an XML signature wrapping weakness in SAML authentication for **SAP NetWeaver AS ABAP** and **ABAP Platform** that could let an authenticated attacker tamper with signed identity data, leading to unauthorized access and privilege escalation. SAP also patched **`CVE-2026-27671`** (CVSS 9.8), an unauthenticated memory corruption bug in the ABAP kernel’s RFC handling that can be triggered with crafted RFC requests. Other critical fixes include **`CVE-2026-40128`**, a directory traversal flaw in **SAP NetWeaver AS Java** Web Container, and **`CVE-2026-22732`**, a Spring Security issue affecting **SAP Commerce Cloud** and **SAP Data Hub** that could expose clients to connection hijacking. Additional patches addressed weaknesses in **SAP S/4HANA**, **ODP Data Replication APIs**, **SAP Wily Introscope Enterprise Manager**, **SAP MDG**, **SAP Business Objects**, and **SAP Fiori launchpad**, including SQL injection, reflected XSS, and Apache Log4j exposure. Canada’s Cyber Centre urged administrators to review SAP advisories, apply updates, and follow recommended mitigations across affected ABAP and Java environments.

SAP released multiple security updates addressing critical vulnerabilities across core enterprise products, including **SAP NetWeaver**, **SAP S/4HANA**, **SAP Commerce Cloud**, **SAP Business Warehouse**, **SAP Business Planning and Consolidation**, **SAP Kernel**, **ABAP Platform**, **SAP NetWeaver Application Server Java**, and **SAP Forecasting & Replenishment**. The fixes covered at least 15 vulnerabilities in both the April-to-June advisories, with several flaws rated **critical** and carrying CVSS scores from **9.0 to 9.9**. Reported impacts included **SQL injection**, **remote code execution**, **operating system command execution**, **directory traversal**, **memory corruption**, **sensitive data exposure**, **denial of service**, privilege abuse, and potential full compromise of confidentiality, integrity, and availability. Among the most severe issues, **CVE-2026-27681** affected SAP Business Planning and Consolidation and SAP Business Warehouse, allowing a low-privileged authenticated attacker to upload a file containing SQL commands and execute arbitrary database operations; SAP said a temporary mitigation was to revoke the `S_GUI` authorization object with Activity 60 (Upload) where possible. Additional high-risk flaws included **CVE-2026-34260** and **CVE-2026-34263** in SAP S/4HANA, SAP Commerce Cloud, and SAP Forecasting & Replenishment, each scored **9.6**, as well as critical June issues in NetWeaver-related components that could enable unauthorized access, file-processing abuse, and system compromise. SAP and national defenders urged organizations to apply vendor-specified patches immediately.

SAP has released security updates addressing 13 newly identified vulnerabilities across its product suite, with particular focus on a maximum-severity flaw in SAP NetWeaver AS Java. The most critical vulnerability, tracked as CVE-2025-42944 and assigned a CVSS score of 10.0, is an insecure deserialization issue that allows unauthenticated attackers to execute arbitrary operating system commands. This flaw can be exploited via the RMI-P4 module by submitting a malicious payload to an open port, potentially compromising the confidentiality, integrity, and availability of affected systems. SAP initially addressed this vulnerability in a previous update, but the latest patch introduces additional hardening measures, including a JVM-wide filter (jdk.serialFilter) to block the deserialization of dangerous classes. The list of classes and packages to be filtered was developed in collaboration with the Onapsis Research Labs and is divided into mandatory and optional sections to maximize protection. In addition to CVE-2025-42944, SAP has patched a directory traversal vulnerability in SAP Print Service (CVE-2025-42937, CVSS 9.8), which could allow unauthenticated attackers to overwrite system files by exploiting insufficient path validation. Another critical issue, CVE-2025-42910 (CVSS 9.0), affects SAP Supplier Relationship Management and involves unrestricted file upload, enabling authenticated attackers to upload arbitrary files, including potentially malicious executables. These vulnerabilities collectively pose significant risks to enterprise environments running SAP solutions, as successful exploitation could lead to system compromise, data loss, or service disruption. SAP has stated that there is currently no evidence of these vulnerabilities being exploited in the wild. Security experts and SAP have emphasized the importance of promptly applying the latest patches to mitigate the risk of exploitation. The additional hardening for the deserialization flaw is particularly notable, as it provides a more robust defense against a class of attacks that have historically been difficult to fully remediate. Organizations are advised to review their SAP deployments, ensure all relevant updates are applied, and follow SAP’s guidance on blocking risky deserialization classes. The disclosure and remediation of these vulnerabilities highlight the ongoing challenges in securing complex enterprise software platforms. SAP’s collaboration with security researchers and the implementation of layered defenses demonstrate a proactive approach to addressing critical security issues. Enterprises relying on SAP NetWeaver and related products should prioritize these updates as part of their regular patch management processes. Failure to address these vulnerabilities could leave systems exposed to remote attacks that require no authentication, significantly increasing the risk profile for affected organizations. The security community continues to monitor for any signs of exploitation and urges vigilance in maintaining up-to-date SAP environments.
