CVE-2026-48206 — Apache Camel JIRA: A set of non-Camel-prefixed Exchange header constants bypass the HTTP header filter, allowing an HTTP client to drive arbitrary JIRA issue operations using the endpoint's configured credentials

Improper Input Validation, Authorization Bypass Through User-Controlled Key vulnerability in Apache Camel JIRA component. The camel-jira producers read their operation parameters - the issue key, project key, transition id, summary, type, assignee, components, watchers, link type, work-log minutes and others - from Exchange message headers. The header constants defined in JiraConstants (for example ISSUE_KEY = IssueKey, ISSUE_PROJECT_KEY = ProjectKey, ISSUE_TRANSITION_ID = IssueTransitionId, LINK_TYPE = linkType) used plain, non-Camel-prefixed values. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a jira: producer, any HTTP client could therefore supply these headers and override the values the route intended, driving JIRA operations against the configured JIRA instance with the endpoint's configured service-account credentials - for example deleting or transitioning an arbitrary issue (via IssueKey / IssueTransitionId), creating an issue in a different project (via ProjectKey), modifying issue fields, adding or removing watchers, or logging work. The operations are bounded by what the configured service account is permitted to do. No credentials are required from the attacker when the bridging consumer is unauthenticated. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, routes that drive JIRA operations via the raw header names must use the CamelJira* names (for example CamelJiraIssueKey) instead of the old values. For deployments that cannot upgrade immediately, strip the camel-jira control headers from any untrusted ingress before the jira: producer (for example removing the IssueKey, ProjectKey, IssueTransitionId and related headers at the start of the route), and set the required JIRA operation parameters from a trusted source.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.6% (30-day exploitation probability)+7
  • Technical severity (medium)+3
  • Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

  • Documented mitigation — camel.apache.org (NIST National Vulnerability Database)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Apache Software Foundation Apache Camel JIRA, Apache Software Foundation Camel).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. Apply the documented mitigations until a definitive fix is available.
  4. Search available logs for exploit probes matching the vulnerability class (input validation), errors and authentication anomalies.
