CVE-2026-61608: Solidinvoice

Medium severity, CVSS 6.8. EPSS: 0.3% chance of exploitation in the next 30 days.

SolidInvoice is an open-source invoicing platform. Prior to version 3.0.1, `UserInvitation` entities have no expiry timestamp. Invitation links mailed to users remain valid indefinitely, meaning a leaked, forwarded, or archived invitation email can be used at any time in the future to join a company or silently add a compromised email account to a company. Version 3.0.1 fixes the issue.
