EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 43.5%, top 1% 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.

angular-base64-upload prior to v0.1.21 is vulnerable to unauthenticated remote code execution via demo/server.php. Exploiting this vulnerability allows an attacker to upload arbitrary content to the server, which can subsequently be accessed through demo/uploads. This leads to the execution of previously uploaded content and enables the attacker to achieve code execution on the server. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
