Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should implement the following specific measures: 1) Conduct a thorough review of user privileges and roles within SAP NetWeaver and ABAP platforms to ensure least privilege principles are enforced, minimizing the number of users with access to vulnerable function modules. 2) Apply SAP security notes and patches as soon as they become available for the affected versions, even if no exploits are currently known. 3) Enable and monitor detailed logging and auditing of remote-enabled function module calls, focusing on unusual access patterns by non-administrative users. 4) Use SAP’s built-in authorization trace tools (e.g., ST01) to detect unauthorized or suspicious function calls. 5) Implement network segmentation and access controls to restrict SAP system access only to trusted users and systems. 6) Educate SAP administrators and security teams about this vulnerability to improve detection and response capabilities. 7) Consider deploying compensating controls such as application-level encryption or masking for particularly sensitive data accessible via these function modules. These steps go beyond generic advice by focusing on SAP-specific tools, user privilege hygiene, and proactive monitoring tailored to the vulnerability’s characteristics.

Description

Due to missing authorization check, an attacker authenticated as a non-administrative user could call a remote-enabled function module. This could enable access to information normally restricted, resulting in low impact on confidentiality. There is no impact on integrity or availability.

Impact

For European organizations, this vulnerability poses a risk of unauthorized information disclosure within SAP environments, potentially exposing sensitive business data, customer information, or intellectual property. Given SAP’s extensive adoption across European industries such as manufacturing, finance, retail, and public sector, unauthorized data access could lead to competitive disadvantage, regulatory compliance issues (e.g., GDPR violations), and reputational damage. Although the impact on integrity and availability is null, the confidentiality breach could facilitate further attacks, including social engineering or privilege escalation. Organizations with complex SAP landscapes and multiple user roles may face challenges in detecting misuse of this vulnerability. The medium severity suggests a moderate risk, but the widespread use of SAP in Europe and the critical nature of data processed by these systems amplify the potential consequences. Additionally, the lack of current exploits provides a window for proactive mitigation before active exploitation occurs.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
