Bolt CMS vulnerabilities

Bolt CMS version 5.1.12 and below contains a vulnerability that allows an authenticated user with ROLE_EDITOR privileges to upload and rename a malicious file, leading to remote code execution.

Bolt CMS renders content field values through Twig's full application-level Environment with no SandboxExtension registered. In src/Entity/Field.php, getTwigValue calls shouldBeRenderedAsTwig, which gates rendering only on the field definition's allow_twig flag and a regex, then compiles and renders the raw value without sandboxing.

In Bolt CMS up to version 3.7.5, in the TextType.php file of the HTML Attribute Handler component, manipulation of the style argument leads to HTML injection. The attack is remote, exploit is public. The GitHub repository is archived and read-only, and the product is no longer supported.

Bolt CMS up to version 3.7.0 contains an SQL injection vulnerability in the 'order' parameter of content listing pages. An authenticated attacker with low privileges can exploit this via the OrderDirective component, allowing extraction of sensitive information.

Bolt CMS version 4.2 and earlier is vulnerable to Remote Code Execution. Unsafe theme rendering allows an authenticated attacker to edit the theme and inject server-side template injection, leading to remote code execution.
