Summary

NOTE: this issue has been disputed by the vendor and third parties. SQL injection vulnerability in Memberlist.php in Simple Machines Forum (SMF) 1.1 rc1 and earlier allows remote attackers to execute arbitrary SQL commands via the start parameter. NOTE: the vendor says that since only one character can be modified, there is no SQL injection. Thus this might be an "invalid SQL syntax error." Multiple followups support the vendor

Exploit prediction

1.38% chance of exploitation in the next 30 days, higher than 72% 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.
