Threat metrics

Exploit Maturity: POC

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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: 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 to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Dec 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.
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 26 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.
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

First, enforce strict input validation and sanitization on the 'openid' parameter at the API gateway or application layer to prevent unauthorized manipulation. Deploy Web Application Firewalls (WAFs) with custom rules targeting suspicious or anomalous requests to the /app-api/v1/members/openid/ endpoint. Conduct thorough access control reviews and implement role-based access controls (RBAC) to ensure minimal privileges are granted to API consumers. Monitor API logs continuously for unusual access patterns or repeated attempts to manipulate the 'openid' parameter, enabling rapid detection and response. Consider isolating or restricting access to the vulnerable API endpoint through network segmentation or IP whitelisting where feasible. Engage in threat hunting exercises to identify any signs of exploitation attempts. Plan for rapid patch deployment once the vendor releases a fix or consider alternative software solutions if the vendor remains unresponsive. Additionally, educate development and security teams about secure API design principles to prevent similar issues in the future.

Description

A vulnerability was found in youlaitech youlai-mall 1.0.0/2.0.0. Affected is an unknown function of the file /app-api/v1/members/openid/. The manipulation of the argument openid results in improper access controls. The attack can be executed remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using youlai-mall, this vulnerability poses a moderate risk of unauthorized access to member data or manipulation of user-related functions. The improper access control could lead to confidentiality breaches, exposing personal or transactional data, which may violate GDPR and other data protection regulations, potentially resulting in legal and financial penalties. Integrity of data could be compromised if attackers modify member information or transaction records, impacting business operations and customer trust. Availability impact is likely limited but cannot be ruled out if the vulnerability is leveraged to disrupt service or escalate attacks. The remote exploitability without user interaction or elevated privileges increases the threat surface, especially for organizations with public-facing APIs. Given the vendor's lack of response, organizations must assume the vulnerability remains unpatched, increasing the urgency for internal mitigations. The impact is particularly significant for e-commerce platforms handling sensitive customer data and payment information, common in European markets. Failure to address this vulnerability could lead to reputational damage and operational disruptions.
