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: High: The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques, for example, circumvention of address space randomization (ASLR) or data execution prevention (DEP) must be performed for the attack to be successful; Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
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: None: There is no loss of confidentiality within 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: 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.
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

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, 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 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

European organizations should immediately audit their newbee-mall-plus installations to identify affected versions (2.4.0 and 2.4.1). In the absence of an official patch, implement strict server-side validation of the userid parameter to ensure it matches the authenticated user's identity. Enhance authorization checks within the executeSeckill function to enforce proper access controls and prevent parameter tampering. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the /seckillExecution/ endpoint, especially those with manipulated userid values. Monitor logs for unusual seckill execution patterns or repeated unauthorized attempts. Consider temporarily disabling the seckill feature during critical sales periods until a patch is available. Engage with the vendor or community for updates and patches, and plan for prompt deployment once released. Additionally, conduct penetration testing focused on authorization controls to identify similar weaknesses.

Description

CVE-2025-12854 is an authorization bypass vulnerability in newbee-mall-plus versions up to 2.4.1, specifically in the executeSeckill function. The flaw allows remote attackers to manipulate the userid argument to bypass authorization controls without authentication or user interaction. Although the exploit is publicly available, the attack complexity is high, making exploitation difficult. The vulnerability has a CVSS 4.0 score of 6.3, indicating medium severity with limited impact on confidentiality and availability but some impact on integrity. No known exploits in the wild have been reported yet. European organizations using newbee-mall-plus for e-commerce should prioritize patching or mitigating this flaw to prevent unauthorized actions in the seckill (flash sale) process.

Impact

For European organizations using newbee-mall-plus, this vulnerability could lead to unauthorized transactions during flash sales, resulting in financial losses, reputational damage, and disruption of sales processes. Attackers could manipulate userid parameters to bypass authorization, potentially enabling fraudulent purchases or denial of legitimate customer transactions. While confidentiality and availability impacts are minimal, the integrity of transaction processes is compromised, which can undermine customer trust and lead to regulatory scrutiny under GDPR if customer data or transaction records are affected. The medium severity and high attack complexity reduce immediate widespread exploitation risk, but the availability of public exploits means targeted attacks against vulnerable installations are plausible. E-commerce businesses in Europe relying on this platform for critical sales events are particularly at risk, especially during high-traffic periods where seckill features are heavily used.
