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: 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: 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: None: There is no impact to availability within 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

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 implement input validation and output encoding on the 'artmed' parameter within the /admin/edit-art-medium-detail.php file to prevent script injection. Until an official patch is released, organizations should consider the following measures: 1) Restrict access to the administrative interface by IP whitelisting or VPN-only access to reduce exposure. 2) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. 3) Educate administrative users about the risks of clicking on suspicious links or inputs. 4) Monitor web server logs for unusual requests targeting the vulnerable parameter. 5) Use web application firewalls (WAF) with rules designed to detect and block XSS payloads targeting the application. 6) Regularly back up data and have incident response plans ready in case of compromise. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable parameter and administrative context.

Description

A vulnerability, which was classified as problematic, has been found in PHPGurukul Art Gallery Management System 1.1. Affected by this issue is some unknown functionality of the file /admin/edit-art-medium-detail.php. The manipulation of the argument artmed leads to cross site scripting. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using the PHPGurukul Art Gallery Management System version 1.1, this vulnerability poses a moderate risk. Successful exploitation could lead to unauthorized access to administrative functions, theft of sensitive information, or manipulation of gallery data. Given that the vulnerability is in an administrative interface, attackers could leverage XSS to hijack sessions of privileged users, potentially leading to broader compromise of the system. This could affect confidentiality and integrity of organizational data, particularly in cultural institutions, museums, or galleries that rely on this software. The impact extends to reputational damage and potential regulatory consequences under GDPR if personal data is compromised. The medium severity and requirement for user interaction mean that exploitation is plausible but not trivial. However, the public availability of exploit details increases the likelihood of targeted attacks, especially against institutions with limited cybersecurity defenses.

Summary

CVE-2025-7767 is a cross-site scripting (XSS) vulnerability identified in version 1.1 of the PHPGurukul Art Gallery Management System, specifically within the /admin/edit-art-medium-detail.php file. The vulnerability arises from improper sanitization or validation of the 'artmed' parameter, which can be manipulated by an attacker to inject malicious scripts. This flaw allows an attacker to execute arbitrary JavaScript code in the context of the affected web application. The attack vector is remote, requiring no prior authentication, but user interaction is necessary to trigger the malicious script, typically by an administrator or user accessing the crafted URL or input. The CVSS 4.0 base score is 5.1, indicating a medium severity level. The vulnerability impacts the confidentiality and integrity of the system by potentially allowing session hijacking, credential theft, or unauthorized actions performed on behalf of the user. Availability impact is minimal. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation. The vulnerability does not require privileges but does require user interaction, which somewhat limits the ease of exploitation. The absence of a patch link suggests that a fix may not yet be available, increasing the urgency for mitigation through other means.
