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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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 20 Mar 2025
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

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 2026-10-25.

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.

AI-suggested

To mitigate this vulnerability, organizations should immediately review and restrict the permissions assigned to the first user created in the danswer-ai/danswer system, ensuring they do not have access to administrative chat data. Implement strict role-based access controls that enforce separation of duties and least privilege principles. Where possible, disable or tightly control the creation of the first user account, using secure provisioning processes and multi-factor authentication. Monitor and audit user activities related to chat access and modifications to detect unauthorized behavior early. Apply any vendor patches or updates once available, and consider isolating the affected system within segmented network zones to limit exposure. Additionally, conduct regular security assessments and penetration tests focused on access control mechanisms within collaboration platforms. Finally, educate administrators and users about the risks of improper user role assignments and the importance of secure account management.

Description

An improper access control vulnerability exists in danswer-ai/danswer version v0.3.94. This vulnerability allows the first user created in the system to view, modify, and delete chats created by an Admin. This can lead to unauthorized access to sensitive information, loss of data integrity, and potential compliance violations.

Impact

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive or confidential information contained within administrative chats, which may include strategic decisions, personal data, or intellectual property. This exposure risks violating the EU's GDPR and other data protection laws, potentially resulting in regulatory fines and reputational damage. The ability to modify or delete admin chats also threatens data integrity and audit trails, complicating incident response and compliance verification. Organizations using danswer-ai/danswer for internal communications or customer interactions may face operational disruptions if critical information is altered or lost. The medium severity rating indicates a moderate but tangible risk, especially in sectors with high compliance requirements such as finance, healthcare, and government. Since the vulnerability can be exploited remotely with low privileges, attackers could leverage compromised or malicious first user accounts to escalate access, increasing the threat surface.

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.
