EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 56% 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.

Versions of the package simple-git before 3.36.0 are vulnerable to Remote Code Execution (RCE) due to an incomplete fix for CVE-2022-25912 that blocks the -c option but not the equivalent --config form. If untrusted input can reach the options argument passed to simple-git, an attacker may still achieve remote code execution by enabling protocol.ext.allow=always and using an ext:: clone source.
