Threat metrics

Exploit Maturity: POC

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: 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 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

CVE published 30 Nov 2025

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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

European organizations should immediately upgrade deco-cx apps to version 0.120.2 or later to remediate the vulnerability. In addition to patching, organizations should implement strict input validation and sanitization on all user-controllable parameters, especially URLs used in server-side requests. Network segmentation should be enforced to limit the server's ability to access internal resources unnecessarily. Employing web application firewalls (WAFs) with rules to detect and block SSRF patterns can provide an additional layer of defense. Monitoring and logging of outbound server requests should be enhanced to detect anomalous or unauthorized requests indicative of SSRF exploitation attempts. Organizations should also review and restrict the server's outbound network permissions to only necessary destinations, minimizing the potential impact of SSRF. Regular security assessments and penetration testing targeting SSRF vulnerabilities can help identify residual risks.

Description

A security vulnerability has been detected in deco-cx apps up to 0.120.1. Affected by this vulnerability is the function AnalyticsScript of the file website/loaders/analyticsScript.ts of the component Parameter Handler. Such manipulation of the argument url leads to server-side request forgery. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 0.120.2 addresses this issue. It is suggested to upgrade the affected component.

Impact

For European organizations, this SSRF vulnerability poses a moderate risk. Organizations using deco-cx apps in affected versions may have their internal networks probed or sensitive internal services accessed by attackers leveraging the SSRF flaw. This can lead to unauthorized data exposure, internal service disruption, or pivoting to more critical systems. The vulnerability's remote exploitability without authentication means attackers can attempt exploitation over the internet, increasing the attack surface. Industries with sensitive data or critical infrastructure relying on deco-cx apps could face increased risk of data breaches or service interruptions. Additionally, SSRF can be used to bypass network access controls, potentially undermining perimeter defenses. The medium CVSS score reflects these risks, but the actual impact depends on the deployment context and network segmentation practices within organizations.
