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: 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.

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 strongly recommends applying Critical Security Patch Update security patches as soon as they become available. Until patches are applied, risk may be reduced by blocking network protocols required by the attack and removing unnecessary privileges or package access from users who do not need them. These mitigations may impact application functionality. Patch status for this specific vulnerability is not explicitly confirmed in the advisory; therefore, check Oracle’s official advisory at https://www.oracle.com/security-alerts/cspujun2026.html for the latest remediation guidance.

Description

Vulnerability in the WebLogic Server product of Oracle Fusion Middleware (component: Console). Supported versions that are affected are 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTPS to compromise WebLogic Server. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in WebLogic Server, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all WebLogic Server accessible data as well as unauthorized access to critical data or complete access to all WebLogic Server accessible data. CVSS 3.1 Base Score 8.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N).

Impact

Successful exploitation can result in unauthorized creation, deletion, or modification of critical data and complete unauthorized access to all data accessible by WebLogic Server. The vulnerability impacts confidentiality and integrity but does not affect availability. It requires network access via HTTPS and user interaction from a third party. The scope of impact may extend beyond WebLogic Server to additional products due to the nature of the vulnerability.

Summary

This vulnerability (CVE-2026-35258) affects Oracle WebLogic Server Console in versions 14.1.2.0.0 and 15.1.1.0.0. It is exploitable by a low privileged attacker with network access over HTTPS and requires user interaction from a person other than the attacker. The vulnerability can lead to unauthorized creation, deletion, or modification of critical data and full access to all WebLogic Server accessible data, impacting confidentiality and integrity. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N with a base score of 8.7. Oracle’s June 2026 Critical Security Patch Update advisory references this vulnerability but does not explicitly confirm a patch or remediation level. Oracle advises customers to apply security patches promptly and consider network protocol blocking or privilege restrictions as temporary mitigations.

CWE-601URL Redirection to Untrusted Site (Open Redirect) (opens in a new tab)
Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
