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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 2026-10-26.

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-2026-23689, organizations should first verify if their SAP SCM installations are running affected versions (SCMAPO 713, 714, SCM 700-702, 712). Since no patches are currently linked, immediate mitigations include: 1) Restricting network access to the vulnerable remote-enabled function modules by applying strict access controls and network segmentation to limit exposure only to trusted users and systems. 2) Implementing monitoring and alerting for abnormal invocation patterns or unusually large loop-control parameter values to detect potential exploitation attempts early. 3) Enforcing least privilege principles to reduce the number of users with access to invoke the vulnerable function modules. 4) Collaborating with SAP support for any available interim fixes or workarounds and applying them promptly once released. 5) Conducting regular audits of user accounts and session activities to identify compromised credentials that could be used to exploit this vulnerability. 6) Considering deployment of runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block suspicious parameter values targeting the vulnerable functions.

Description

Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.

Impact

The primary impact of CVE-2026-23689 is denial of service, which can severely disrupt business operations relying on SAP Supply Chain Management systems. Organizations may experience system unavailability, degraded performance, or complete service outages, affecting supply chain processes such as order fulfillment, inventory management, and logistics coordination. This can lead to operational delays, financial losses, and reputational damage. Since the vulnerability requires authenticated access with regular user privileges, insider threats or compromised user accounts can be leveraged to exploit it. The scope of affected systems is broad given the widespread use of SAP SCM in manufacturing, retail, and logistics sectors globally. Although confidentiality and integrity are not impacted, the availability disruption alone can have cascading effects on enterprise resource planning and critical supply chain functions.

CWE-606Unchecked Input for Loop Condition (opens in a new tab)
Base weakness
The product does not properly check inputs that are used for loop conditions, potentially leading to a denial of service or other consequences because of excessive looping.
Implementation
Do not use user-controlled data for loop conditions.
