EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 10.0 under NVD CVSS v3. EPSS exploit probability: 1.7%, top 25% 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.

WeBid 1.0.2 contains a remote code injection vulnerability in the converter.php script, where unsanitized input in the to parameter of a POST request is written directly into includes/currencies.php. This allows unauthenticated attackers to inject arbitrary PHP code, resulting in persistent remote code execution when the modified script is accessed or included by the application.
