| CVE | Severity | CVSS | Published | Summary |

| CVE-2018-10125 | MEDIUM | 6.1 | Mar 16, 2020 | Contao before 4.5.7 has XSS in the system log. |
| CVE-2024-30262 | MEDIUM | 5.9 | Apr 9, 2024 | Contao is an open source content management system. Prior to version 4.13.40, when a frontend member changes their password in the personal data or the password lost module, the corresponding remember-me tokens are not removed. If someone compromises an account and is able to get a remember-me token, changing the password would not be enough to reclaim control over the account. Version 4.13.40 contains a fix for the issue. As a workaround, disable "Allow auto login" in the login module. |
| CVE-2024-45604 | MEDIUM | 4.3 | Sep 17, 2024 | Contao is an Open Source CMS.

There are no known workarounds for this vulnerability. |

Starting in version 2.0.0 and prior to versions 4.13.40 and 5.3.4, it is possible to inject CSS styles via BBCode in comments. Installations are only affected if BBCode is enabled. Contao versions 4.13.40 and 5.3.4 have a patch for this issue. As a workaround, disable BBCode for comments. |
| CVE-2023-29200 | MEDIUM | 4.3 | Apr 25, 2023 | Contao is an open source content management system. Prior to versions 4.9.40, 4.13.21, and 5.1.4, logged in users can list arbitrary system files in the file manager by manipulating the Ajax request.
