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 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

To mitigate CVE-2026-23683, organizations should first monitor SAP’s official channels for patches or updates addressing this vulnerability and apply them promptly once available. In the interim, implement strict access controls and review user roles and permissions within the SAP Fiori environment to ensure the principle of least privilege is enforced. Conduct thorough audits of user privileges for the Intercompany Balance Reconciliation app to identify and restrict any unnecessary elevated access. Employ network segmentation and limit access to SAP Fiori apps to trusted internal networks or VPNs to reduce exposure. Enable and monitor detailed logging and alerting for suspicious privilege escalations or unauthorized access attempts within SAP systems. Additionally, consider deploying compensating controls such as multi-factor authentication (MFA) for all users accessing SAP Fiori apps to reduce the risk of compromised credentials being exploited. Regularly train and raise awareness among SAP users about the risks of privilege misuse and the importance of secure credential handling.

Description

SAP Fiori App Intercompany Balance Reconciliation does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges. This has low impact on confidentiality, integrity and availability are not impacted.

Impact

The primary impact of this vulnerability is the potential for privilege escalation within the SAP Fiori Intercompany Balance Reconciliation app. An authenticated user could gain unauthorized access to higher privilege functions, potentially leading to unauthorized viewing or modification of financial reconciliation data. Although the confidentiality impact is low, unauthorized privilege escalation can facilitate further malicious activities or fraud within financial processes. Since integrity and availability are not directly affected, the risk is somewhat contained but still significant given the sensitive nature of financial data and processes handled by this app. Organizations relying on SAP S/4HANA Core versions 102 to 106 are at risk, particularly those with multiple users having authenticated access to the Fiori apps. The vulnerability could be leveraged by insiders or attackers who have compromised low-privilege accounts, increasing the threat surface. The absence of known exploits reduces immediate risk, but the medium severity and ease of exploitation (low complexity, network accessible) warrant prompt attention.

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.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
