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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Oct 2025
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.

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 2026-10-26.

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. Immediately identify and inventory all Liferay Portal and DXP instances within the organization to determine exposure. 2. Apply any available official patches or updates from Liferay as soon as they are released. 3. If patches are not yet available, restrict access to the OpenAPI endpoints by configuring web application firewalls (WAFs), reverse proxies, or network ACLs to block unauthorized requests to the OpenAPI YAML URL paths. 4. Implement authentication and authorization controls on API documentation endpoints to ensure only authorized users can access them. 5. Monitor web server and application logs for unusual or repeated access attempts to OpenAPI-related URLs, indicating potential reconnaissance activity. 6. Conduct internal security assessments and penetration testing to verify that OpenAPI files are not accessible without proper authorization. 7. Educate development and operations teams about the risks of exposing API specifications publicly and enforce secure coding and deployment practices. 8. Consider disabling or limiting the generation and exposure of OpenAPI documentation in production environments if not required. 9. Maintain an up-to-date asset management and vulnerability scanning program to detect similar issues proactively.

Description

Liferay Portal 7.4.0 through 7.4.3.109, and Liferay DXP 2023.Q4.0 through 2023.Q4.5, 2023.Q3.1 through 2023.Q3.7, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions does not properly restrict access to OpenAPI in certain circumstances, which allows remote attackers to access the OpenAPI YAML file via a crafted URL.

Impact

For European organizations, this vulnerability poses a risk of unauthorized information disclosure that can facilitate further attacks against critical web applications and backend services. The exposure of OpenAPI specifications can reveal internal API structures, authentication mechanisms, and business logic, enabling attackers to craft sophisticated exploits or automate attacks. This can lead to data breaches, service disruptions, or compromise of sensitive business processes. Organizations in sectors such as finance, government, healthcare, and telecommunications that rely on Liferay Portal or DXP for their digital services are particularly vulnerable. The medium severity rating indicates that while immediate system compromise is unlikely, the vulnerability significantly lowers the barrier for attackers to gain deeper insights into the target environment. Additionally, the lack of authentication requirements means that attackers can exploit this vulnerability remotely without needing valid credentials or user interaction, increasing the attack surface. The impact is exacerbated if the exposed APIs control sensitive operations or access confidential data. Therefore, European entities must assess their exposure and implement mitigations promptly to prevent potential exploitation.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
