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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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.

CVE published 1 Sep 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.
Not in CISA KEV and no source reports exploitation

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.

What to do

Upgrade KnowageLabs Knowage-Server to 8.1.37.

AI-suggested

1. Immediate upgrade to Knowage-Server version 8.1.37 or later, where the SSRF vulnerability is patched, is the most effective mitigation. 2. Implement strict input validation and sanitization on any user-controllable parameters that trigger server-side requests to prevent injection of arbitrary URLs or hosts. 3. Employ network segmentation and firewall rules to restrict the Knowage-Server's outbound HTTP requests only to trusted and necessary internal and external endpoints, minimizing the attack surface. 4. Monitor and log outbound requests from the Knowage-Server to detect unusual or unauthorized internal network scanning activities. 5. Apply the principle of least privilege to user accounts, limiting the ability of users to trigger SSRF-related functionality unless necessary. 6. Conduct regular security awareness training to reduce the risk of social engineering attacks that could facilitate exploitation requiring user interaction. 7. Use Web Application Firewalls (WAFs) with SSRF detection capabilities to block suspicious request patterns targeting the vulnerable endpoints. 8. Perform internal network vulnerability assessments to identify and remediate other weaknesses that could be exploited following reconnaissance.

Description

Knowage is an open source analytics and business intelligence suite. Prior to version 8.1.37, Knowage is vulnerable to server-side request forgery. The vulnerability allows attackers to send requests to arbitrary hosts/paths. Since the attacker is not able to read the response, the impact of this vulnerability is limited. However, an attacker could be able to leverage this vulnerability to scan the internal network. This issue has been patched in version 8.1.37.

Impact

For European organizations using Knowage-Server versions prior to 8.1.37, this SSRF vulnerability poses a moderate security risk primarily related to internal network reconnaissance. Attackers exploiting this flaw could map internal services and infrastructure, potentially identifying further vulnerabilities or misconfigurations within the internal network. While direct data theft or service disruption is unlikely due to the inability to read response data and the low severity rating, the reconnaissance capability can be a stepping stone for more sophisticated attacks. Organizations in sectors with sensitive internal networks, such as finance, healthcare, and government, could face increased risk if attackers leverage this vulnerability to gain insights into their internal environment. Additionally, the requirement for limited privileges and user interaction means insider threats or social engineering attacks could facilitate exploitation. The vulnerability does not directly compromise confidentiality, integrity, or availability but can indirectly weaken the security posture by exposing internal network details.
