Description
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.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.camel:camel-jira, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.apache.camel:camel-jira to 4.14.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-48206 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
When an Apache Camel route bridges an HTTP consumer to a JIRA producer, an unauthenticated client can bypass header filtering. This allows the client to manipulate JIRA issue operations by supplying specific non-Camel-prefixed headers, potentially leading to unauthorized actions within the bounds of the configured…
To mitigate this issue, configure routes that bridge an HTTP consumer to a JIRA producer to strip all non-Camel-prefixed JIRA control headers (e.g., IssueKey, ProjectKey, IssueTransitionId) from untrusted ingress before they reach the JIRA producer. Ensure that required JIRA operation parameters are set from a trusted source within the route.Source: Red Hat security advisory for CVE-2026-48206 (CC BY 4.0)
