CVE-2026-73842
Unauthenticated internal API exposure allows secrets theft, workload mutation, and remote command execution.
Is CVE-2026-73842 being exploited?
Not confirmed. CVE-2026-73842 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-73842?
CVE-2026-73842 is rated Critical with a CVSS score of 9.0. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-73842?
Yes. A fix has been recorded for CVE-2026-73842. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-73842 affect?
CVE-2026-73842 affects OpenChoreo versions before 1.0.3, 1.1.3, and 1.2.0-rc.2, cluster-gateway internal APIs: /api/proxy/, /api/exec/, /api/wirelogs/. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
