EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
