Zarro Technology · Security briefing
Since this morning’s briefing, CVE records have been published for three self-hosting issues. The underlying reports and fixes predate today: these are newly registered CVEs, not claims of newly discovered vulnerabilities or confirmed new attacks. Scores below use the CNA’s CVSS v4.0 assessments.
CVE-2026-116068 (8.7)
The CVE record published today covers Dokploy through 0.30.10. An authenticated organisation owner or administrator can act on another tenant’s applications by supplying a foreign application identifier, potentially changing environment variables, deployment settings or availability.
Review retained application/audit logs and configuration history for changes made by users outside the owning organisation, unexpected deployments and altered environment settings. These are investigation leads; the cited disclosures do not establish active exploitation or provide campaign-specific IPs or hashes.
Verify that your deployed build contains the maintainer’s organisation-boundary fix, commit b3cd3c5. The cited CVE record does not identify a fixed tagged release, so do not assume that any particular later version is safe without checking. Until verified, avoid hosting mutually untrusted organisations on the affected control plane.

CVE-2026-116070 (6.9)
Today’s record covers the third-party dqzboy/Docker-Proxy project through 5.1.9, not Docker Engine generally. Missing authentication in the hubcmdui configuration routes can expose notification credentials and allow configuration changes, including monitoring destinations.
Review available web logs for unexpected access to /api/config, then compare current notification destinations, menu links and proxy settings with your approved configuration. Legitimate requests use this route too; a request alone does not prove compromise. No campaign-specific IoCs are established by the cited record.
Deploy a maintainer build containing fix a173bef, which restricts sensitive configuration reads and requires authentication for writes. Confirm the deployed image includes it; the CVE record gives no fixed release number. Restrict or disable the affected management interface pending remediation. If credentials may have been exposed, rotate the affected bot tokens and webhook credentials.

CVE-2026-116187 (6.1)
The record published today assigns a CVE to an earlier rclone advisory affecting 1.68.0 through 1.75.1 when running serve s3 --auth-proxy for multiple tenants. An authenticated tenant who obtains another tenant’s bucket, object and upload identifier may interfere with in-flight multipart uploads and access associated metadata. This is not a general flaw in ordinary rclone copy operations.
Check the server’s version and launch configuration. The following command is read-only; run it in the environment hosting the service, including inside its container where applicable:
rclone versionUpgrade to 1.75.2 or a later fixed release. Review retained S3 request logs for multipart-upload operations inconsistent with tenant ownership. The cited sources do not provide campaign IoCs or establish active exploitation; missing or incomplete logs cannot rule out misuse.
