HIGHPre-NVD 7.57.5—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 64% 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, the DataGrid LiveComponent deserializes a context prop value using PHP's unserialize() after receiving it from the client. Because the prop is marked writable: true, an authenticated attacker can supply an arbitrary PHP serialized payload. Version 3.0.1 fixes the issue.
