The S5 Register module by JoomlaShine/Shape5, versions 1.0.0 through 3.0.0, is affected by an SQL injection vulnerability. Update the module to a release above 3.0.0 (3.1.0 or later, current builds are 4.x). This rule matches a module, not a component - look for "S5 Register" under Extensions, Modules rather than in the components list.
Affected versions: ≥ 1.0.0 and ≤ 3.0.0
Official record: cve.org · NVD
Every connected Joomla site is checked against this rule on each audit, and flagged if it runs an affected version.
