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: 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 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: 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.

AI-suggested

Implement strict file upload validation to restrict allowed file types and scan uploaded PDFs for embedded scripts or suspicious content.
Sanitize and validate all user inputs related to file uploads and metadata to prevent injection of malicious payloads.
Apply output encoding and Content Security Policy (CSP) headers to limit script execution from untrusted sources.
Restrict access to uploaded PDF files by implementing authentication and authorization checks rather than serving them via public static URLs.
Monitor and log file upload activities to detect anomalous behavior or unauthorized uploads.
Educate users about the risks of clicking on untrusted links, especially those pointing to uploaded documents.
Regularly update jshERP to the latest versions once patches become available and subscribe to vendor security advisories.
Employ web application firewalls (WAFs) with rules to detect and block XSS payloads in file uploads and HTTP requests.
Conduct periodic security assessments and penetration testing focusing on file upload functionalities.
Isolate ERP systems and limit network exposure to reduce the attack surface.

Description

jshERP versions 3.5 and earlier are affected by a stored XSS vulnerability. This vulnerability allows attackers to upload PDF files containing XSS payloads. Additionally, these PDF files can be accessed via static URLs, making them accessible to all users.

Impact

For European organizations, this vulnerability poses a moderate risk to the confidentiality and integrity of ERP system data. Attackers exploiting this flaw could steal session tokens, impersonate users, or perform unauthorized actions within jshERP, potentially leading to data leakage or manipulation of business-critical information. Since ERP systems often integrate with financial, HR, and operational data, the impact could extend to regulatory compliance issues such as GDPR violations if personal data is exposed. The requirement for low privileges to upload files means insider threats or compromised accounts could be leveraged to exploit this vulnerability. The static URLs make it easier for attackers to share malicious links internally or externally, increasing the likelihood of successful phishing or social engineering campaigns. Although availability is not directly impacted, the trustworthiness and integrity of the ERP system could be undermined, affecting business operations and decision-making. European organizations in manufacturing, logistics, and services sectors that rely on jshERP are particularly at risk, especially if they have not implemented strict file upload controls or content sanitization.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
