Iris is a web collaborative platform that helps incident responders share technical details during investigations. Prior to version 2.4.24, the DFIR-IRIS datastore file management system has a vulnerability where mass assignment of the file_local_name field combined with path trust in the delete operation enables authenticated users to delete arbitrary filesystem paths. The vulnerability manifests through a three-step attack chain: authenticated users upload a file to the datastore, update the file's file_local_name field to point to an arbitrary filesystem path through mass assignment, then trigger the delete operation which removes the target file without path validation. This vulnerability is fixed in 2.4.24.
With a CVSS score of 9.6, this vulnerability is classified as critical, indicating a severe risk to organizations that use the affected version of dfir-iris iris. The potential for exploitation highlights an urgent need for immediate action to patch systems and prevent unauthorized access.
Risk to organizations includes unauthorized deletion of critical files, which can disrupt operations and compromise incident response efforts. Given the low attack complexity and the fact that no user interaction is required, attackers may leverage this vulnerability effectively through a network.
Organizations should prioritize patching immediately. The vulnerability's presence in versions prior to 2.4.24 necessitates swift action to mitigate potential impacts.
The exploitation status remains unconfirmed, with no known exploits or public proof-of-concept reported. However, the critical nature of the vulnerability calls for heightened awareness in the security community.
Vulnerability Details
The vulnerability allows authenticated users to delete arbitrary filesystem paths due to improper handling of the file_local_name field within the DFIR-IRIS datastore. This oversight stems from a lack of validation during the delete operation. The vulnerability is formally categorized under several Common Weakness Enumeration (CWE) identifiers, including CWE-73 (External Control of File Name or Path), CWE-434 (Unrestricted File Upload), and CWE-915 (Improperly Controlled Modification of Object Attribute).
The vulnerability's CVSS score of 9.6, categorized as critical, indicates it poses a significant threat. It has a low attack complexity, requires low privileges, and does not necessitate user interaction, making it easier to exploit. The potential impacts on confidentiality are none, while integrity and availability can be severely affected.
The vulnerability was disclosed on January 12, 2026, and affects all versions of dfir-iris iris prior to 2.4.24, as identified in the configurations.
Technical Analysis
The root cause of the vulnerability lies in the DFIR-IRIS datastore's file management system, where insufficient validation allows the mass assignment of the file_local_name field. This oversight creates a vector for exploitation through a three-step attack sequence. Attackers begin by uploading a file, manipulating the file_local_name to point to a malicious path, and subsequently executing the delete operation, which removes files without verifying their validity.
The attack vector is network-based, with low complexity, requiring only low privileges for exploitation. Importantly, no user interaction is necessary. The impacts of successful exploitation include high integrity and availability impacts, as unauthorized file deletions can disrupt critical processes and data integrity.
Risk & Impact Analysis
The deployment of this vulnerability significantly increases the risk profile for organizations utilizing dfir-iris iris. The ability for authenticated users to delete arbitrary filesystem paths can have devastating effects, particularly in environments where data integrity and operational uptime are paramount. The blast radius of this vulnerability extends to all users with authenticated access, thereby amplifying the risk of insider threats.
Organizations must assess the urgency of this vulnerability based on its CVSS score of 9.6. The critical nature of the vulnerability and its potential for exploitation necessitate immediate action. Failure to address this vulnerability can lead to unauthorized access to sensitive information, operational disruptions, and long-term reputational damage.
