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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 20 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

1. Apply official Oracle patches immediately once available to remediate the vulnerability. 2. Restrict network access to PeopleSoft SCM Purchasing interfaces by implementing network segmentation and firewall rules limiting HTTP access to trusted internal IPs only. 3. Enforce the principle of least privilege for all user accounts within PeopleSoft, ensuring that users have only the minimum necessary permissions to perform their roles. 4. Implement multi-factor authentication (MFA) for all access to PeopleSoft systems to reduce the risk of compromised credentials being used to exploit this vulnerability. 5. Monitor application logs and network traffic for unusual activities such as unexpected data modifications or access patterns. 6. Conduct regular security assessments and penetration tests focused on PeopleSoft environments to identify and remediate potential weaknesses. 7. Educate users and administrators about this vulnerability and the importance of secure credential management. 8. Maintain an incident response plan tailored to PeopleSoft environments to quickly address any exploitation attempts.

Description

Vulnerability in the PeopleSoft Enterprise SCM Purchasing product of Oracle PeopleSoft (component: Purchasing). The supported version that is affected is 9.2. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise SCM Purchasing. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PeopleSoft Enterprise SCM Purchasing accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise SCM Purchasing accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N).

Impact

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of supply chain data managed through PeopleSoft SCM Purchasing. Unauthorized data manipulation could disrupt procurement processes, cause financial discrepancies, or lead to compliance violations, especially in regulated industries such as manufacturing, automotive, pharmaceuticals, and retail. Data disclosure could expose sensitive supplier or contract information, impacting competitive advantage and privacy obligations under GDPR. The medium severity score reflects that while availability is not impacted, the integrity and confidentiality breaches could have significant operational and reputational consequences. Given the interconnected nature of supply chains, exploitation could cascade to affect partners and customers. Organizations relying heavily on PeopleSoft SCM Purchasing for critical procurement functions must consider this vulnerability a priority to avoid potential business disruption and regulatory penalties.
