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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: 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.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), GitHub proofs of concept, the Metasploit, Exploit-DB and nuclei-templates index as of 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

Oracle's April 2026 Critical Patch Update advisory includes numerous security patches across Oracle products. However, the provided advisory content does not explicitly confirm the availability of a patch or official fix for CVE-2026-22006. Customers should consult the Oracle Critical Patch Update advisory and associated patch availability documentation at https://www.oracle.com/security-alerts/cpuapr2026.html for the latest remediation status and apply relevant patches promptly if available. Since this is not a cloud service, remediation depends on customer patching.

Description

CVE-2026-22006 is a medium severity vulnerability in Oracle PeopleSoft Enterprise HCM Human Resources version 9.2, specifically in the Employee Snapshot component. It allows a low privileged attacker with network access via HTTP to perform unauthorized read and write operations on accessible data, including update, insert, or delete actions. Successful exploitation requires human interaction from a person other than the attacker and may impact additional products beyond PeopleSoft HCM. The vulnerability has a CVSS 3.1 base score of 5.4, reflecting limited confidentiality and integrity impacts without availability impact. Oracle has published a Critical Patch Update advisory referencing multiple patches but does not explicitly confirm a patch for this specific CVE in the provided content. No known exploits are reported in the wild at this time.

Impact

Successful exploitation can lead to unauthorized reading and modification (update, insert, delete) of some data accessible through PeopleSoft Enterprise HCM Human Resources 9.2. The attack requires human interaction from a user other than the attacker and may have broader impact on other Oracle products due to scope change. There is no impact on availability. No known exploits in the wild have been reported.

Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
