Description

Impact

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 — including the cloud metadata endpoint at http://169.254.169.254/ — 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.

Affected code paths:

  • src/firefighter/raid/views/__init__.py — CreateJiraBotView
  • src/firefighter/raid/serializers.py — LandbotIssueRequestSerializer.attachments
  • src/firefighter/raid/client.py — RaidJiraClient.add_attachments_to_issue

Patches

Fixed in firefighter-incident 0.0.54:

  • CreateJiraBotView now enforces BearerTokenAuthentication + IsAuthenticated.
  • attachments URLs are validated: http(s) scheme only, max 10 URLs, rejection of any host resolving to a private, loopback, link-local, reserved, multicast or unspecified IP (IPv4 and IPv6).
  • Fixes an unrelated KeyError('attachments') surfaced during regression testing.

Users should upgrade to 0.0.54 or later.

Workarounds

Until upgrade is possible, any one of the following blocks end-to-end exploitation:

  • Restrict ingress access to /api/v2/firefighter/raid/jira_bot to trusted networks only (VPN, internal load balancer).
  • Rotate or revoke the Jira API token configured as RAID_JIRA_API_PASSWORD; this breaks jira.create_issue() before the vulnerable attachment fetch is reached (legitimate traffic is also blocked — emergency mitigation only).
  • Enforce IMDSv2 with HttpPutResponseHopLimit=1 on EC2/EKS nodes. This does not fix the SSRF itself but neutralises the IAM-credential-theft path.

Resources

  • CWE-918: Server-Side Request Forgery
  • CWE-306: Missing Authentication for Critical Function
Risk Scores
Base Score
9.9

The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a low impact on the integrity of the data. There is a low impact on the availability of the system.
