Overview

CVE-2026-42864 is a critical-severity vulnerability. It was published on May 11, 2026 and has a CVSS 3.1 base score of 9.9 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.9, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

FireFighter is an incident management application. Prior to 0.0.54, the POST /api/v2/firefighter/raid/jira_bot endpoint (CreateJiraBotView) is reachable without authentication (permission_classes = [permissions.AllowAny]). Its attachments payload is fetched server-side via httpx.get() with no URL validation, then uploaded as an attachment on the Jira ticket that gets created. An unauthenticated caller able to reach the ingress can coerce the pod into fetching arbitrary URLs and exfiltrate the response as a Jira attachment. On EC2/EKS deployments that do not enforce IMDSv2, this allows theft of the temporary AWS credentials attached to the pod's IAM role. The docstring on the view claims a Bearer token is required, but the code does not enforce it. This vulnerability is fixed in 0.0.54.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
