Unauthenticated network-reachable auth bypass (CWE-290) in an SSO plugin plausibly yields arbitrary/admin account takeover, giving full C/I/A; I agree with the vendor pending confirmation of the sparse description.

Unauthenticated Broken Authentication in Headless Single Sign On <= 1.7.0 versions.
AnalysisAI
Unauthenticated attackers can bypass the authentication logic of the miniOrange Headless Single Sign On WordPress plugin at versions up to and including 1.7.0, gaining access as arbitrary users - potentially administrators - with full confidentiality, integrity, and availability impact (CVSS 3.1 9.8). Per the assessed vector (AV:N/AC:L/PR:N/UI:N), exploitation requires no credentials, no user interaction, and no client-side prerequisites against an affected installation; the practical limiting factor is deployment, since this is a niche headless-SSO component with a modest install footprint, and the precise configuration state that triggers the bypass is not described in the advisory. …

| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch status for CVE-2026-62108 is not confirmed from the available data: no vendor-released patch or fixed version is identified at time of analysis, and no fix reference (release tag, pull request, or commit) is provided in the advisory set. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress installations running the miniOrange Headless Single Sign On plugin at version 1.7.0 or earlier and, unless headless SSO is business-critical, deactivate and remove the plugin immediately; where removal is not feasible, place the affected SSO endpoints behind network allowlisting or WAF virtual patching that blocks unauthenticated requests to the plugin's authentication routes, and alert the security operations team to hunt for anomalous logins, unexpected administrator account creation, or privilege changes. …
