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

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 deployments of zhuimengshaonian wisdom-education to identify affected versions (1.0.0 to 1.0.4). In the absence of an official patch, implement strict server-side validation and authorization checks on the subjectId parameter within the WrongBookController API endpoint to ensure users can only access resources they are permitted to. Employ web application firewalls (WAFs) to detect and block suspicious requests manipulating subjectId or exhibiting anomalous patterns. Conduct thorough logging and monitoring of API access to detect potential exploitation attempts. Limit network exposure of the affected application by restricting access to trusted networks or VPNs. Engage with the vendor for patch timelines and apply updates promptly once available. Additionally, perform regular security assessments and penetration tests focusing on authorization controls to prevent similar vulnerabilities.

Description

A vulnerability was detected in zhuimengshaonian wisdom-education up to 1.0.4. The affected element is an unknown function of the file src/main/java/com/education/api/controller/student/WrongBookController.java. Performing manipulation of the argument subjectId results in authorization bypass. The attack can be initiated remotely. The exploit is now public and may be used.

Impact

For European organizations, particularly educational institutions or edtech providers using the zhuimengshaonian wisdom-education platform, this vulnerability poses a risk of unauthorized access to student data or restricted application functions. Such unauthorized access could lead to data leakage, privacy violations under GDPR, and potential reputational damage. Since the vulnerability allows remote exploitation without authentication, attackers could operate from outside the network perimeter, increasing the risk of widespread exploitation. The partial confidentiality impact means sensitive information could be exposed, which is critical in education environments handling minors' data. Additionally, unauthorized access could be leveraged to manipulate educational records or gain footholds for further attacks. The medium severity score reflects moderate risk but should not be underestimated given the sensitivity of educational data and regulatory requirements in Europe.

Summary

CVE-2025-11321 is an authorization bypass vulnerability identified in the zhuimengshaonian wisdom-education software, specifically affecting versions 1.0.0 through 1.0.4. The vulnerability resides in an unspecified function within the WrongBookController.java source file, part of the API controller handling student-related operations. By manipulating the subjectId parameter, an attacker can bypass authorization mechanisms, gaining unauthorized access to resources or actions that should be restricted. The attack vector is remote network access, requiring no authentication or user interaction, which increases the attack surface. The CVSS 4.0 vector indicates low complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impact on confidentiality (VC:L), with no impact on integrity or availability. Although no exploits have been observed in the wild, public exploit code is available, suggesting that attackers could leverage this vulnerability to access sensitive educational data or functionality. The lack of patches or official remediation links in the provided data suggests that organizations must implement compensating controls or monitor for exploitation attempts until a patch is available. This vulnerability highlights the importance of strict authorization checks on input parameters in web applications, especially those handling sensitive educational data.
