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: 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: 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: 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: None: There is no loss of integrity within 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 the June 2026 Critical Security Patch Update, which includes patches addressing CVE-2026-46791. Customers should review the patch availability documentation linked in the Oracle advisory to obtain and install the appropriate patches for Oracle WebCenter Content 14.1.2.0.0. Until patches are applied, risk may be reduced by blocking network protocols required for exploitation and by removing unnecessary privileges from users to limit attack surface. Oracle advises applying patches promptly to avoid exploitation risks. Patch status is not explicitly confirmed in the advisory excerpt, so customers should consult the vendor advisory for current remediation guidance.

Description

CVE-2026-46791 is a high-severity vulnerability in Oracle WebCenter Content 14.1.2.0.0 that allows an unauthenticated attacker with network access via HTTP to gain unauthorized access to critical data. The vulnerability impacts confidentiality but does not affect integrity or availability. Oracle has included this vulnerability in its June 2026 Critical Security Patch Update advisory, which addresses numerous vulnerabilities across multiple products. Oracle strongly recommends applying the provided security patches promptly to mitigate the risk. No explicit patch version or temporary fix is detailed in the advisory excerpt, but the advisory references patch availability documents for affected products. Workarounds such as blocking network protocols or removing unnecessary privileges may reduce risk until patches are applied.

Impact

Successful exploitation of this vulnerability allows an unauthenticated attacker to gain unauthorized access to critical or all accessible data in Oracle WebCenter Content 14.1.2.0.0. The impact is limited to confidentiality compromise; integrity and availability are not affected according to the CVSS vector. This could lead to exposure of sensitive information managed by the affected Oracle WebCenter Content instance.

Summary

CVE-2026-46791 is a vulnerability in Oracle WebCenter Content (component: Content Server) version 14.1.2.0.0 that allows an unauthenticated attacker with network access via HTTP to compromise the system. The vulnerability results in unauthorized access to critical data or potentially all accessible data within Oracle WebCenter Content. The CVSS 3.1 base score is 7.5, indicating high severity, with a vector indicating network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, and high confidentiality impact without integrity or availability impact. Oracle has published this vulnerability in its June 2026 Critical Security Patch Update advisory, which includes patches for this and other vulnerabilities across multiple Oracle products. The advisory strongly urges customers to apply patches without delay and provides documentation links for patch availability and installation instructions. No direct exploit in the wild is reported at this time.

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Separation of Privilege
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.
