CVE-2026-48206
MEDIUMCVE-2026-48206 is a medium-severity (CVSS 5.3) Improper Input Validation vulnerability in org.apache.camel:camel-jira. O3 Security confirms whether CVE-2026-48206 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
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
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2026-48206 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 365,950 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.camel:camel-jira. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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.
How O3 protects you
O3 pinpoints whether CVE-2026-48206 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-48206. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
