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: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
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: 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 Subsequent 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), 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.

AI-suggested

European organizations should implement strict input validation and sanitization for all SVG uploads, ideally disallowing SVG files if not strictly necessary. Employ server-side SVG sanitization libraries that remove scripts and event handlers before storing or serving SVG content. Restrict the '/api/v1/user-avatar' endpoint to accept only safe image formats such as PNG or JPEG where possible. Implement Content Security Policy (CSP) headers to limit script execution from untrusted sources. Monitor logs and network traffic for unusual POST requests to the avatar upload endpoint and for anomalous user behavior. Enforce strong authentication and session management to reduce the impact of potential session hijacking. Conduct regular security assessments and penetration testing focusing on file upload functionalities. Stay alert for official patches or updates from Apidog and apply them promptly once available. Consider isolating or sandboxing user-uploaded content to minimize script execution risks. Educate users about the risks of interacting with suspicious content and maintain incident response plans tailored to XSS attacks.

Description

CVE-2025-41085 is a stored Cross-Site Scripting (XSS) vulnerability in Apidog Web Platform version 2.7.15. The flaw arises because SVG image uploads to the '/api/v1/user-avatar' endpoint are not properly sanitized, allowing attackers to embed malicious scripts within SVG files. These scripts are stored on the server and executed in the context of any user who accesses the compromised resource, potentially leading to session hijacking, credential theft, or unauthorized actions. The vulnerability requires an authenticated user to upload a malicious SVG and some user interaction to trigger the payload. The CVSS 4.0 score is 5.1, indicating medium severity. There are no known exploits in the wild currently, and no official patches have been released yet.

Impact

For European organizations, exploitation of this vulnerability could lead to unauthorized access to user sessions, data theft, and potential lateral movement within affected systems. Organizations relying on Apidog Web Platform for internal or customer-facing applications may face reputational damage, regulatory scrutiny under GDPR if personal data is compromised, and operational disruptions. The stored XSS nature means that once a malicious SVG is uploaded, any user accessing the affected resource is at risk, potentially amplifying the impact in environments with many users. Attackers could leverage this to conduct phishing, spread malware, or escalate privileges. The medium severity score reflects moderate risk, but the real-world impact depends on the deployment context, user base size, and exposure of the vulnerable endpoint. European sectors with high regulatory requirements, such as finance, healthcare, and government, could face significant compliance and legal consequences if exploited. Additionally, the vulnerability could be used as an initial foothold in multi-stage attacks targeting European enterprises using the platform.
