Medium (6.3) in concretecms concrete cms. EPSS 0.7% chance of exploitation in the next 30 days.
Concrete CMS (formerly concrete5) below 8.5.10 and between 9.0.0 and 9.1.2 did not use strict comparison for the legacy_salt so that limited authentication bypass could occur if using this functionality. Remediate by updating to Concrete CMS 9.1.3+ or 8.5.10+.
