Availability: None

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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: 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 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.

What to do

AI-suggested

Given the absence of official patches at the time of disclosure, European organizations should implement immediate compensating controls. These include: 1) Restricting access to the Change Governance module to trusted users only and enforcing the principle of least privilege to minimize the number of users with write permissions capable of injecting malicious scripts. 2) Implementing Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the Product Manager interface. 3) Conducting thorough input validation and output encoding on any custom integrations or extensions interacting with the Product Manager to prevent injection of malicious scripts. 4) Enhancing user awareness and training to recognize suspicious behaviors and avoid interacting with untrusted links or content within the platform. 5) Monitoring logs and user activity for anomalies indicative of XSS exploitation attempts. 6) Preparing for rapid deployment of official patches once released by Dassault Systèmes and testing updates in controlled environments before production rollout. 7) Considering network segmentation to isolate critical Product Manager instances from broader corporate networks to limit lateral movement in case of compromise.

Description

A stored Cross-site Scripting (XSS) vulnerability affecting Change Governance in Product Manager from Release 3DEXPERIENCE R2022x through Release 3DEXPERIENCE R2025x allows an attacker to execute arbitrary script code in user's browser session.

Impact

For European organizations, the impact of CVE-2025-4990 can be substantial, especially those relying on Dassault Systèmes' 3DEXPERIENCE platform for product lifecycle management and change governance. The vulnerability could lead to unauthorized access to sensitive intellectual property, design documents, and change management workflows, potentially resulting in industrial espionage, data breaches, and operational disruptions. Given the collaborative nature of Product Manager, exploited XSS could facilitate lateral movement within corporate networks or compromise multiple users simultaneously. This risk is heightened in sectors such as aerospace, automotive, manufacturing, and engineering, where Dassault Systèmes products are widely used and where data confidentiality and integrity are critical. Additionally, regulatory compliance frameworks in Europe, such as GDPR, impose strict data protection requirements; a breach resulting from this vulnerability could lead to significant legal and financial penalties. The vulnerability's ability to affect confidentiality and integrity without impacting availability means that attacks might remain stealthy and undetected for extended periods, increasing potential damage.
