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: 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.
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

Definitions: FIRST CVSS v4.0 specification.

Exploitation evidence

Disclosed: evidence found.
CVE published 22 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
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), 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

Since no official patches or updates are currently available, European organizations should take immediate steps to mitigate risk. These include: 1) Implement strict network segmentation and firewall rules to restrict access to the /topiccategory/queryAll endpoint only to trusted internal IPs or VPN users. 2) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized requests targeting this endpoint. 3) Conduct thorough access control reviews and harden authorization logic within the platform if source code or configuration access is available. 4) Monitor logs and network traffic for unusual or unauthorized access attempts to the affected endpoint. 5) Engage with the vendor or community to obtain patches or updates as soon as they are released. 6) Consider temporary disabling or restricting the vulnerable functionality if feasible without disrupting business operations. 7) Educate security teams and incident responders about the vulnerability and potential indicators of compromise to enable rapid detection and response.

Description

A flaw has been found in fuyang_lipengjun platform 1.0. The affected element is the function TopicCategoryController of the file /topiccategory/queryAll. This manipulation causes improper authorization. The attack is possible to be carried out remotely. The exploit has been published and may be used.

Impact

For European organizations using the fuyang_lipengjun platform version 1.0, this vulnerability could lead to unauthorized access to sensitive topic category data or related platform functions. This may result in confidentiality breaches, exposing internal or customer data, which could violate GDPR and other data protection regulations, leading to legal and financial penalties. The ability to exploit this remotely without authentication increases the risk of external attackers gaining access. Although the impact on integrity and availability is low, unauthorized data disclosure alone can damage organizational reputation and trust. Organizations in sectors handling sensitive or regulated data (e.g., finance, healthcare, government) are particularly at risk. Additionally, attackers could leverage this vulnerability as a foothold for further lateral movement or privilege escalation within the network if combined with other vulnerabilities or misconfigurations.
