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: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Sep 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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
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), the Metasploit, Exploit-DB and nuclei-templates index as of 1 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

Upgrade Erudika scoold to version 1.69.0 or later, where this authorization issue is fixed. No other mitigation is required as the vendor has provided an official fix.

Description

Scoold is a Q&A and a knowledge sharing platform for teams. Prior to 1.69.0, authenticated users who are not members of a private space can create content in questions belonging to that space because src/main/java/com/erudika/scoold/controllers/QuestionController.java in QuestionController.reply() and src/main/java/com/erudika/scoold/controllers/CommentController.java in CommentController.createAjax() do not apply the canAccessSpace authorization check used by the question read path. With scoold.is_default_space_public set to false and private spaces in use, a user with a valid session and a known or enumerable question identifier can send requests to POST /question/{id} and POST /comment, causing replies and comments to be stored in a thread the user cannot read. This permits unauthorized modification of private discussions and can trigger notifications that reveal the existence or metadata of private activity. This issue is fixed in version 1.69.0.

Impact

The vulnerability allows authenticated users without membership in a private space to modify content by adding replies and comments to questions in that space. This unauthorized modification can disrupt private discussions and cause notifications that may leak information about the existence or metadata of private activities. There is no direct confidentiality impact on the content itself, but the integrity of private discussions is compromised.

Summary

In Erudika scoold versions before 1.69.0, the authorization check 'canAccessSpace' is not applied in the methods handling replies and comments (QuestionController.reply() and CommentController.createAjax()). When the configuration 'scoold.is_default_space_public' is set to false and private spaces are used, authenticated users with valid sessions can post replies and comments to questions in private spaces they do not have access to by sending POST requests to /question/{id} and /comment endpoints. This results in unauthorized content creation in private threads, potentially exposing metadata through notifications. The vulnerability is addressed in version 1.69.0.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
