Summary

app/plug/attachment/controller/admincontroller.php in SDCMS 1.6 allows reading arbitrary files via a /?m=plug&c=admin&a=index&p=attachment&root= directory traversal. The value of the root parameter must be base64 encoded (note that base64 encoding, instead of URL encoding, is very rare in a directory traversal attack vector).

Exploit prediction

2.02% chance of exploitation in the next 30 days, higher than 81% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
