Summary
IBM WebSphere Automation is affected by a MongoDB security vulnerability (CVE-2025-14847).
Vulnerability Details
CVEID: CVE-2025-14847
DESCRIPTION: Mismatched length fields in Zlib compressed protocol headers may allow a read of uninitialized heap memory by an unauthenticated client. This issue affects all MongoDB Server v7.0 prior to 7.0.28 versions, MongoDB Server v8.0 versions prior to 8.0.17, MongoDB Server v8.2 versions prior to 8.2.3, MongoDB Server v6.0 versions prior to 6.0.27, MongoDB Server v5.0 versions prior to 5.0.32, MongoDB Server v4.4 versions prior to 4.4.30, MongoDB Server v4.2 versions greater than or equal to 4.2.0, MongoDB Server v4.0 versions greater than or equal to 4.0.0, and MongoDB Server v3.6 versions greater than or equal to 3.6.0.
CWE: CWE-130: Improper Handling of Length Parameter Inconsistency
CVSS Source: cna@mongodb.com
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
Affected Products and Versions
IBM recommends that customers update to a supported version by referring the End of Support dates for WebSphere Automation.
| Affected Product(s) | Version(s) |
| IBM WebSphere Automation | 1.10.0, 1.11.0 |
Remediation/Fixes
IBM strongly recommends addressing the vulnerability now by upgrading to 1.11.1 or higher.
Follow https://www.ibm.com/docs/en/ws-automation?topic=installing-validating-installation to confirm the WebSphere Automation operator version.
Follow https://www.ibm.com/docs/en/ws-automation?topic=installing-updating-websphere-automation to update the WebSphere Automation operator installation.
Workarounds and Mitigations
IBM strongly suggest you upgrade immediately. However, if you cannot upgrade immediately, disable zlib compression on the MongoDB Server by performing the following steps.
1. Check if the zlib library is listed under compressions using the following command:
oc exec -it <mongo-pod-name> \
-c mongo \
-n <namespace> \
-- sh -c '
mongosh \
--host localhost \
--tls \
--tlsCAFile data/configdb/tls.crt \
--tlsCertificateKeyFile work-dir/mongo.pem \
-u "$(head -n 1 work-dir/credentials.txt)" \
-p "$(tail -n 1 work-dir/credentials.txt)" \
--eval "db.serverStatus().network.compression"
'
2. If the library exists, edit the wsa-mongo-conf config map and add the following under the net field.
net:
compression:
compressors: snappy,zstd
3. Perform command : oc rollout restart statefulset wsa-mongo
4. Verify zlib library is removed using the first command

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
