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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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 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.

What to do

AI-suggested

European organizations should implement the following specific mitigations: 1) Enforce strict role-based access controls (RBAC) and regularly audit approver roles to ensure only necessary personnel have deletion privileges. 2) Implement monitoring and alerting on deletion activities within the Bank Account Application to detect unauthorized or anomalous deletions promptly. 3) Apply SAP security notes and patches as soon as they become available for this CVE to remediate the missing authorization checks. 4) Conduct periodic reviews of attachment management workflows and consider additional application-level logging to maintain traceability of changes. 5) Employ multi-factor authentication (MFA) for approver accounts to reduce the risk of credential compromise. 6) Train staff on the importance of safeguarding privileged accounts and recognizing suspicious activities. 7) If possible, restrict network access to SAP S/4HANA interfaces to trusted internal networks or VPNs to reduce exposure.

Description

SAP S/4HANA (Bank Account Application) does not perform necessary authorization checks. This allows an authenticated 'approver' user to delete attachment from bank account application of other user, leading to a low impact on integrity, with no impact on the confidentiality of the data or the availability of the application.

Impact

For European organizations using SAP S/4HANA, particularly the Bank Account Application module, this vulnerability poses a risk to data integrity within financial workflows. Unauthorized deletion of attachments could disrupt audit trails, compliance documentation, and internal controls related to bank account management. This could lead to regulatory scrutiny, especially under stringent European financial regulations such as GDPR and PSD2, where accurate record-keeping is mandatory. While confidentiality and availability are not directly impacted, the integrity compromise could facilitate fraud or financial mismanagement if malicious insiders exploit this flaw. Organizations relying heavily on SAP S/4HANA for banking or financial operations may face operational disruptions or reputational damage if such unauthorized deletions occur unnoticed. Given the requirement for an authenticated approver role, the threat is more relevant to insider threats or compromised privileged accounts rather than external attackers without credentials.

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.
