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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent 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 Subsequent 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.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CISA SSVC, the Metasploit, Exploit-DB and nuclei-templates index as of 8 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

Version 2.1.18 added a warning when SERVER_REQUEST_WHITELIST is not configured, suggesting that configuring this whitelist may help mitigate the risk. Users should review and configure SERVER_REQUEST_WHITELIST to restrict allowed outbound requests. Monitor vendor advisories for official fixes or updates.

Description

NocoBase versions up to 2.1.20 contain a server-side request forgery (SSRF) vulnerability that allows authenticated administrators to make arbitrary outbound HTTP requests. This can be exploited via workflow request nodes, custom request action buttons, or the AI plugin. The vulnerability enables attackers to access internal network resources, including loopback addresses, private IP ranges, and cloud instance metadata endpoints, potentially leading to internal network reconnaissance and retrieval of IAM role credentials. Version 2.1.18 introduced a warning when the SERVER_REQUEST_WHITELIST is not configured, but no fix is explicitly stated.

Impact

The vulnerability allows authenticated administrators to perform SSRF attacks that can lead to internal network reconnaissance and unauthorized access to sensitive cloud instance metadata, including IAM role credentials. This could facilitate further attacks within the internal network or cloud environment. The CVSS 4.0 score of 5.1 reflects a medium severity impact with network attack vector, low complexity, and no user interaction required.

Summary

CVE-2026-58468 is an SSRF vulnerability in NocoBase through version 2.1.20. Authenticated administrators can supply malicious URLs to various server request interfaces, causing the server to issue arbitrary HTTP requests. This allows targeting of internal network addresses and cloud metadata services, facilitating internal port scanning, host discovery, and credential theft from instance metadata endpoints.
