For all three currently supported Contao versions, Contao 4.13.49, 5.3.15 and 5.4.3 fix two security vulnerabilities. One was reported by Jakob Steeg from usd AG and the other was discovered by Andreas Schempp from the core team. The Contao core team has categorised the potential damage of one of the two vulnerabilities as «high». A quick update is therefore essential in any case, there are no workarounds.
