Authorization Bypass in Apache Camel JIRA Component

Executive Summary

CVE-2026-48206 is a medium-severity security vulnerability in the Apache Camel camel-jira component. It arises because certain Exchange message headers used by the camel-jira producers, such as IssueKey, ProjectKey, and IssueTransitionId, do not have the Camel-specific prefix and thus bypass the HTTP header filtering mechanism. This allows an attacker to supply these headers via an HTTP request and override intended values, causing unauthorized JIRA operations to be executed using the endpoint's configured service-account credentials without needing any attacker credentials.

Specifically, an attacker can delete or transition arbitrary issues, create issues in different projects, modify issue fields, add or remove watchers, or log work by manipulating these headers. The vulnerability affects Apache Camel versions from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, and from 4.19.0 before 4.21.0.

The issue is fixed by renaming these headers to use CamelJira-prefixed constants (e.g., CamelJiraIssueKey) to ensure proper filtering, and users are advised to upgrade to fixed versions or mitigate by stripping untrusted headers before the jira: producer.

Impact Analysis

This vulnerability can allow an attacker to perform unauthorized JIRA operations using the service account configured in the Apache Camel route without needing any credentials. Potential impacts include:

• Deleting or transitioning arbitrary JIRA issues.
• Creating issues in projects not intended by the route configuration.
• Modifying issue fields, adding or removing watchers, or logging work on issues.

These actions can lead to unauthorized data manipulation, disruption of project workflows, and potential loss or corruption of issue tracking data.

Detection Guidance

This vulnerability can be detected by monitoring HTTP requests to routes bridging HTTP consumers to jira: producers for the presence of non-Camel-prefixed headers such as IssueKey, ProjectKey, IssueTransitionId, and related headers. These headers should normally not be accepted from untrusted sources.

You can inspect incoming HTTP requests or logs for these headers to identify potential exploitation attempts.

Suggested commands include using network packet capture or HTTP log inspection tools to filter for these headers. For example, using tcpdump or tshark to capture HTTP traffic and grep or jq to search for these header names.

• tcpdump -A -s 0 'tcp port 80 or tcp port 443' | grep -i 'IssueKey'
• tshark -Y 'http.header contains "IssueKey" or http.header contains "ProjectKey" or http.header contains "IssueTransitionId"'
• Review application logs or HTTP access logs for presence of these headers in requests to the vulnerable routes.

Mitigation Strategies

Immediate mitigation steps include upgrading Apache Camel to a fixed version: 4.14.8 if on the 4.14.x LTS stream, 4.18.3 if on the 4.18.x stream, or 4.21.0 for other versions.

If upgrading immediately is not possible, strip the camel-jira control headers (such as IssueKey, ProjectKey, IssueTransitionId, and related headers) from any untrusted ingress before the jira: producer in your routes.

Additionally, update routes to use the new CamelJira-prefixed header names (e.g., CamelJiraIssueKey) instead of the old non-prefixed values after upgrading.

• Upgrade Apache Camel to version 4.14.8, 4.18.3, or 4.21.0 depending on your release stream.
• Remove untrusted HTTP headers like IssueKey, ProjectKey, IssueTransitionId before they reach the jira: producer.
• Modify routes to use CamelJira* header names for JIRA operations.
