RSA access key disclosure via internal-index logging
Published Feb 18, 2026 · Updated Feb 18, 2026
Sensitive-data exposure in Splunk Enterprise affected releases allows remote authenticated users to read an RSA access key in plaintext. The splunkd component writes the accessKey value from authentication.conf into the _internal index without redaction. Exposure requires a Search Head Cluster deployment and a role allowed to read _internal; the disclosed consequence is plaintext secret access.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.0 <10.0.2
- Affected versionversion=9.2 <9.2.11
- Affected versionversion=9.3 <9.3.9
- Affected versionversion=9.4 <9.4.7
