How to Fix CVE-2026-42864

To remediate this vulnerability, upgrade all affected Firefighter incident dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

firefighter-incident fixed: 0.0.54
pip install firefighter-incident>=0.0.54
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

pip show firefighter-incident

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-42864, inspect your installed packages using pip:

pip show firefighter-incident

Analyze the terminal output to locate any version of Firefighter incident in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.54), your application is affected.

Note: The pip show firefighter-incident command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-306: Missing Authentication for Critical Function, where the product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. In Firefighter incident, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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
