CVE-2026-61614: Solidinvoice

Medium severity, CVSS 5.9. EPSS: 0.4% chance of exploitation in the next 30 days.

SolidInvoice is an open-source invoicing platform. Prior to version 3.0.1, the REST API authenticator accepts bearer tokens via a `?token=` URL query parameter as a fallback to the `X-API-TOKEN` header. This causes long-lived API credentials to be recorded in server access logs, proxy logs, browser history, and HTTP Referer headers sent to third-party origins. Version 3.0.1 fixes the issue.
