Scope: Changed
Confidentiality: High
Integrity: High
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 15 Sep 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 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.

AI-suggested

Oracle has released security patches for this vulnerability as part of the September 2026 Critical Security Patch Update. Customers should apply the relevant patches for Oracle Identity Manager Connector versions 12.2.1.4.0 and 14.1.2.1.0 promptly. Oracle strongly recommends remaining on actively-supported versions and applying security patches without delay to mitigate this vulnerability.

Description

A critical vulnerability exists in the Oracle Identity Manager Connector component of Oracle Fusion Middleware, affecting versions 12.2.1.4.0 and 14.1.2.1.0. This vulnerability allows an unauthenticated attacker with access to the physical communication segment of the hardware running the connector to compromise it. Successful exploitation can lead to unauthorized creation, deletion, or modification of critical data accessible by the Oracle Identity Manager Connector. The vulnerability has a CVSS 3.1 base score of 9.3, indicating high confidentiality and integrity impacts. Oracle has released security patches addressing this and many other vulnerabilities in their September 2026 Critical Security Patch Update. Customers are strongly advised to apply these patches promptly to mitigate the risk.

Impact

Exploitation of this vulnerability can lead to unauthorized creation, deletion, or modification of critical data accessible by the Oracle Identity Manager Connector. It can also result in unauthorized access to critical data or complete access to all data accessible by the connector. The vulnerability affects confidentiality and integrity but does not impact availability. The scope of impact may extend beyond the connector to additional Oracle products.
