Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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 impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Oct 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

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 2026-10-26.

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.

What to do

AI-suggested

To mitigate CVE-2025-62393, organizations should first verify if they are running version 5.0.0 of the affected software and prioritize upgrading to a patched version once available. In the absence of an immediate patch, administrators should audit and tighten access control policies around course overview data, ensuring that permission checks are enforced at all output points. Implement role-based access controls (RBAC) with the principle of least privilege to restrict user access strictly to necessary course information. Monitor logs for unusual access patterns to course data, especially from users with low privileges. Additionally, consider network segmentation and multi-factor authentication to reduce the risk of unauthorized access. Engage with the software vendor or community for updates and apply security advisories promptly. Regular security assessments and penetration testing focused on access control mechanisms can help identify similar weaknesses.

Description

A flaw was found in the course overview output function where user access permissions were not fully enforced. This could allow unauthorized users to view information about courses they should not have access to, potentially exposing limited course details.

Impact

The primary impact of CVE-2025-62393 is the unauthorized disclosure of course information, which could include course content summaries, schedules, or participant lists, depending on the application context. For educational institutions, training providers, or corporate learning platforms, this leakage could violate privacy policies, intellectual property protections, or contractual confidentiality agreements. While the vulnerability does not allow modification or disruption of services, the exposure of sensitive data can undermine trust and compliance with data protection regulations such as GDPR or FERPA. Attackers with low-level access could leverage this information for social engineering, reconnaissance, or to escalate privileges. The scope is limited to users with some authenticated access, but the ease of exploitation and network accessibility increase risk. Organizations worldwide that rely on this software version for course management are at risk of data leakage incidents.
