EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 79% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

An issue in the billing and license activation subsystem allows remote attackers to bypass payment authorization workflows. By exploiting insufficient cryptographic validation or lack of server-side state verification on promotional/lifetime-deal (LTD) redemption codes, an unauthenticated attacker can forge valid redemption tokens or replay existing single-use codes to activate permanent, tier-highest paid subscriptions without a financial transaction.
