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: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 2026-10-26.

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

To mitigate this vulnerability, organizations should implement strict input validation and output encoding on all user-supplied data, particularly the 'Description' field in chatgpt-web. Employing Content Security Policy (CSP) headers can reduce the impact of XSS by restricting the execution of unauthorized scripts. Regularly updating the application to the latest version once a patch is released is critical. In the absence of an official patch, organizations should consider applying temporary workarounds such as disabling or sanitizing the affected input fields, or using web application firewalls (WAFs) configured to detect and block typical XSS payloads. Additionally, educating users about the risks of interacting with suspicious links or inputs can reduce the likelihood of successful exploitation. Monitoring logs for unusual activity related to the Description parameter can help detect attempted attacks early.

Description

A vulnerability, which was classified as problematic, has been found in Chanzhaoyu chatgpt-web 2.11.1. This issue affects some unknown processing. The manipulation of the argument Description with the input <image src onerror=prompt(document.domain)> leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-249779.

Impact

For European organizations using the Chanzhaoyu chatgpt-web 2.11.1 application, this vulnerability could lead to targeted XSS attacks that compromise user sessions or trick users into performing unintended actions. While the direct impact on confidentiality is minimal, the integrity of user interactions and data could be compromised. Attackers could leverage this vulnerability to conduct social engineering attacks or steal session tokens if the application handles sensitive data or authentication cookies insecurely. The risk is heightened in environments where chatgpt-web is integrated with internal communication or customer-facing portals, potentially exposing employees or customers to malicious scripts. Given the low CVSS score and the requirement for user interaction, the threat is moderate but should not be ignored, especially in sectors with strict data protection regulations such as GDPR. Failure to address this vulnerability could lead to reputational damage and regulatory scrutiny if exploited to compromise personal data.

Summary

CVE-2023-7215 is a cross-site scripting (XSS) vulnerability identified in version 2.11.1 of the Chanzhaoyu chatgpt-web application. The vulnerability arises from improper input validation and sanitization of the 'Description' argument, which allows an attacker to inject malicious HTML/JavaScript code. Specifically, the exploit involves injecting an image tag with an onerror event handler, such as <image src onerror=prompt(document.domain)>, which triggers a JavaScript prompt displaying the domain name. This vulnerability is classified under CWE-79, indicating it is a reflected or stored XSS issue. The attack can be initiated remotely without requiring authentication, but user interaction is necessary to trigger the malicious script execution (e.g., by viewing a crafted page or input). The CVSS v3.1 base score is 3.5, indicating a low severity level, primarily because the impact on confidentiality is none, integrity impact is low, and availability impact is none. The vulnerability does not appear to have known exploits in the wild yet, and no official patches have been linked or published at this time. However, the public disclosure of the exploit details increases the risk of exploitation attempts. The vulnerability could allow attackers to execute arbitrary scripts in the context of the victim's browser session, potentially leading to session hijacking, phishing, or defacement if combined with other weaknesses.
