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

Exploitation evidence

Detectable: no evidence on record.

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.

What to do

AI-suggested

European organizations should immediately audit their use of the PHP-Code-For-Unlimited-File-Upload component to identify affected instances. Employing Content Security Policy (CSP) headers can reduce the impact of injected scripts by restricting script execution sources. Web Application Firewalls (WAFs) should be configured to detect and block typical XSS payloads targeting this parameter. Additionally, organizations should monitor web logs for suspicious requests to /f.php and educate users about phishing risks. If feasible, replacing or removing the vulnerable component until a patch is released is recommended. Regular security testing and code reviews should be conducted to detect similar vulnerabilities proactively.

Description

A weakness has been identified in lokibhardwaj PHP-Code-For-Unlimited-File-Upload up to 124fe96324915490c81eaf7db3234b0b4e4bab3c. This affects an unknown part of the file /f.php. This manipulation of the argument h causes cross site scripting. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be exploited. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, this XSS vulnerability poses a moderate risk primarily to web applications that integrate or rely on the PHP-Code-For-Unlimited-File-Upload component. Successful exploitation could lead to theft of user credentials, session tokens, or other sensitive information via malicious script execution. This can facilitate further attacks such as account takeover or phishing. Additionally, compromised web pages can damage organizational reputation and user trust, especially in sectors handling sensitive personal data under GDPR regulations. While the vulnerability does not directly compromise backend systems or data integrity, the potential for lateral attacks through stolen credentials or session hijacking is a concern. Organizations using this component in customer-facing portals, intranets, or administrative interfaces are particularly at risk. The lack of vendor response and patches increases exposure time, necessitating proactive mitigation.

Summary

CVE-2025-10246 is a cross-site scripting (XSS) vulnerability identified in the PHP-Code-For-Unlimited-File-Upload project maintained by lokibhardwaj. The vulnerability exists in the /f.php file, specifically in the handling of the 'h' parameter. An attacker can manipulate this parameter to inject malicious scripts, which are then executed in the context of the victim's browser. This type of vulnerability allows remote attackers to execute arbitrary JavaScript code without authentication or privileges, potentially leading to session hijacking, defacement, or redirection to malicious sites. The product follows a rolling release model, so exact affected versions are not clearly delineated beyond the commit hash 124fe96324915490c81eaf7db3234b0b4e4bab3c. The vendor has not responded to disclosure attempts, and no official patches are currently available. The vulnerability has a CVSS 4.0 base score of 5.1, indicating a medium severity level. The vector indicates network attack vector, low attack complexity, no privileges required, but user interaction is necessary for exploitation. The vulnerability does not affect confidentiality or availability significantly but impacts integrity via script injection and user trust. No known exploits are currently observed in the wild, but public exploit code exists, increasing the risk of exploitation.
