# CVE-2026-50633: Apache CXF JNDI Injection vulnerability in DispatchMDBMessageListenerImpl

**Signal:** Normal patch cycle. No exploitation signal; fix it in your next routine update if you are affected. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 1.3% , percentile 70: FIRST’s model estimates a 1.3% chance of exploitation activity in the next 30 days, higher than 70% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.apache.cxf:cxf-integration-jca (Maven) >= 4.2.0, < 4.2.2, fixed in 4.2.2 ; org.apache.cxf:cxf-integration-jca (Maven) < 4.1.7, fixed in 4.1.7 . Check your lockfile, including transitive dependencies.

## What it is

A JNDI Injection vulnerability has been discovered in Apache CXF's JCA integration module, which can allow for code execution, if an attacker is able to manipulate the JCA deployment descriptor (ra.xml) or runtime activation parameters. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue.

## Affected packages

- Maven `org.apache.cxf:cxf-integration-jca` >= 4.2.0, < 4.2.2 → fixed: 4.2.2
- Maven `org.apache.cxf:cxf-integration-jca` < 4.1.7 → fixed: 4.1.7

## Affected products (CVE record)

- Apache Software Foundation Apache CXF: 4.2.0 < 4.2.2, 4.0.0 < 4.1.7, < 3.6.12

## Severity

- CISA-ADP CVSS 3.1: 8.1 `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`
- redhat-SADP CVSS 3.1: 8.1 `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.27% probability of exploitation activity in the next 30 days; percentile 70.
