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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: None: There is no loss of integrity within 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Nov 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 4 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 the Oqtane Framework to version 10.3.0 or later, where this SSRF vulnerability is fixed. No other mitigation or temporary workaround is indicated by the vendor advisory.

Description

CVE-2026-122008 is a server-side request forgery (SSRF) vulnerability in the Oqtane Framework versions before 10.3.0. It affects the UploadFile endpoint in FileController.cs, allowing authenticated users to make the server fetch arbitrary URLs without proper validation. This can lead to unauthorized access to internal resources such as cloud metadata services or localhost management interfaces. Attackers can save fetched responses as files in their user folders and retrieve them via the download endpoint, potentially exfiltrating sensitive internal data or enumerating internal network hosts and ports. The vulnerability is fixed in version 10.3.0.

Impact

An authenticated registered user can exploit this SSRF vulnerability to access internal network resources that are normally inaccessible externally. This includes cloud instance metadata services and localhost management interfaces. The attacker can exfiltrate sensitive internal data by saving and downloading the fetched responses. The vulnerability may also allow enumeration of internal hosts and ports, increasing the attack surface for further exploitation.

Summary

The Oqtane Framework prior to version 10.3.0 contains an SSRF vulnerability in the UploadFile endpoint of FileController.cs. Authenticated users can supply a URL parameter to HttpClient.GetStreamAsync without validation of scheme, host, or IP address. This allows the server to fetch arbitrary URLs, including internal services such as cloud instance metadata or localhost interfaces. Attackers can store the fetched content as files in their user folder and download them, enabling data exfiltration or internal network reconnaissance. The issue is resolved in version 10.3.0.
