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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable 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 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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.

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

Apply vendor patches immediately once available to address the vulnerability in the unpackFile function.
Until patches are released, implement strict input validation and sanitization on all archive files processed by the platform, ensuring no path traversal sequences are allowed.
Configure the application environment to restrict file system permissions, limiting the ability of the application to write outside designated directories.
Employ application-layer firewalls or intrusion detection systems to monitor and block suspicious archive uploads or extraction attempts.
Conduct regular security audits and code reviews focusing on file handling routines.
Educate administrators and developers about secure archive processing practices.
Isolate critical systems running lsfusion to reduce exposure to remote attacks.
Monitor logs for unusual file extraction activities that may indicate exploitation attempts.

Description

A weakness has been identified in lsfusion platform up to 6.1. This vulnerability affects the function unpackFile of the file server/src/main/java/lsfusion/server/physics/dev/integration/external/to/file/ZipUtils.java. This manipulation causes path traversal. It is possible to initiate the attack remotely.

Impact

For European organizations using the lsfusion platform, this vulnerability can lead to unauthorized file system modifications, potentially resulting in data breaches, service disruption, or system compromise. Sensitive data could be overwritten or exposed, and attackers might implant malicious files to facilitate further attacks. Organizations in sectors such as finance, government, healthcare, and critical infrastructure that rely on lsfusion for business processes are at higher risk. The ability to exploit remotely without authentication increases the threat landscape, especially for internet-facing deployments. Disruption of business operations or leakage of confidential information could lead to regulatory penalties under GDPR and damage to reputation. The medium severity rating suggests that while the vulnerability is not immediately catastrophic, the consequences can be significant if exploited in high-value environments.

Summary

CVE-2025-13265 identifies a path traversal vulnerability in the lsfusion platform, specifically affecting versions 6.0 and 6.1. The vulnerability resides in the unpackFile function of the ZipUtils.java file, which is responsible for extracting files from archives. Due to insufficient validation of file paths during extraction, an attacker can craft malicious archive files containing file paths that traverse directories (e.g., using '../' sequences) to write files outside the intended extraction directory. This can lead to overwriting critical system or application files, potentially allowing code execution, privilege escalation, or data corruption. The vulnerability is remotely exploitable without requiring user interaction or elevated privileges, increasing its risk profile. The CVSS 4.0 score is 5.3 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, and the ease of exploitation. No known exploits have been reported in the wild yet, but the vulnerability's nature makes it a candidate for future exploitation. The lack of vendor patches at the time of publication necessitates immediate mitigation efforts by affected organizations. The vulnerability highlights the importance of secure file handling and input validation in software dealing with archive extraction.
