CVE-2026-22783: Iris Allows Arbitrary File Deletion via Mass Assignment in Datastore File Management

Iris is a web collaborative platform that helps incident responders share technical details during investigations. Prior to 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.

Security readout for executives and security teams

Plain-English summary

CVE-2026-22783 affects DFIR-IRIS iris-web before 2.4.24. An authenticated user can manipulate datastore file metadata so a later delete action removes arbitrary server files. This can disrupt the IRIS platform or other files reachable by the application process. The vendor advisory says 2.4.24 fixes the issue.

Executive priority

Treat as urgent for any IRIS deployment, especially in incident response environments. A compromised or malicious authenticated account could damage investigation data or application stability. Prioritize upgrading before relying on IRIS for active investigations.

Technical view

The issue combines mass assignment of file_local_name with insufficient path validation in datastore file deletion. The CVSS 3.1 score is 9.6: network-accessible, low complexity, low privileges, no user interaction, with high integrity and availability impact. Listed weaknesses include CWE-434, CWE-73, and CWE-915.

Likely exposure

Exposure is limited to organizations running dfir-iris iris-web versions earlier than 2.4.24, especially where untrusted or broadly provisioned users can authenticate to IRIS. Public internet exposure increases operational risk, but authentication is required according to the advisory.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The vulnerability is serious because a low-privileged authenticated user could cause destructive file deletion through normal application functionality if the instance is vulnerable.

Researcher notes

Evidence is strongest from the GitHub security advisory and linked fix commit. The description identifies the vulnerable field and delete-path trust issue, but no public exploitation confirmation is provided in the supplied sources.

Mitigation direction

  • Upgrade dfir-iris iris-web to version 2.4.24 or later.
  • Review the GitHub advisory for any updated vendor guidance.
  • Restrict IRIS access to trusted networks and authenticated users only.
  • Review user permissions and remove unnecessary datastore access.

Validation and detection

  • Inventory IRIS deployments and confirm running version.
  • Verify no instance is below 2.4.24.
  • Review application logs for unusual datastore file metadata changes or delete activity.
  • Confirm access controls limit who can upload, modify, and delete datastore files.
