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: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
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 5 Nov 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

Users should monitor the vendor's communications for updates. In the meantime, restricting or sanitizing input on the goodsName parameter and improving validation of uploaded files to ensure only legitimate image formats are accepted may reduce risk. Since the vendor has not responded, no official remediation is currently available.

Description

A security flaw has been discovered in newbee-ltd newbee-mall up to 1.0.0. Impacted is an unknown function of the file controller/common/UploadController.java of the component Goods Save Endpoint. Performing a manipulation of the argument goodsName results in cross site scripting. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. ImageIO.read() is a format-agnostic read - it returns non-null for a polyglot PNG|<img onerror> payload, which is exactly why the "image-only" guard is bypassable; the attacker-controlled suffix + /upload/** static mapping is what turns the upload into persisted XSS rather than a one-shot. The project was informed of the problem early through an issue report but has not responded yet.

Impact

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to session hijacking, defacement, or other malicious actions against users of the application. The vulnerability is persistent, meaning the malicious payload remains stored on the server and can affect multiple users. The CVSS score of 5.1 (medium) reflects the moderate impact and ease of exploitation with low attack complexity and no privileges required.

Summary

This vulnerability affects newbee-ltd newbee-mall up to version 1.0.0 in the UploadController.java component's Goods Save Endpoint. An attacker can manipulate the goodsName argument to perform a cross-site scripting attack. The issue is due to the use of ImageIO.read() which is format-agnostic and can be tricked by a polyglot PNG payload containing an onerror event handler. This bypasses the 'image-only' upload guard and results in persisted XSS via the attacker-controlled suffix and static mapping of the upload path. The vulnerability is remotely exploitable and public exploit code is available. The vendor has been notified but has not yet provided a patch or mitigation.
