Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Laravel is a web application framework. Laravel contain a possible cross-site scripting (XSS) vulnerability in the Blade templating engine. A broken HTML element may be clicked and the user taken to another location in their browser due to XSS. This is due to the user being able to guess the parent placeholder SHA-1 hash by trying common names of sections. If the parent template contains an exploitable HTML structure an XSS vulnerability can be exposed. This vulnerability has been patched by determining the parent placeholder at runtime and using a random hash that is unique to each request.

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
Laravel is a web application framework. Versions of Laravel before 6.20.11, 7.30.2 and 8.22.1 contain a query binding exploitation. This same exploit applies to the illuminate/database package which is used by Laravel. If a request is crafted where a field that is normally a non-array value is an array, and that input is not validated or cast to its expected type before being passed to the query builder, an unexpected number of query bindings can be added to the query. In some situations, this will simply lead to no results being returned by the query builder; however, it is possible certain queries could be affected in a way that causes the query to return unexpected results.

Laravel environment manipulation via query string
When the `register_argc_argv php` directive is set to `on` , and users call any URL with a special crafted query string, they are able to change the environment used by the framework when handling the request.

Incorrect Authorization
An issue was discovered in Laravel before 6.18.35 and 7.x before 7.24.0. The $guarded property is mishandled in some situations involving requests with JSON column nesting expressions.

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: none.

Laravel has a File Validation Bypass
When using wildcard validation to validate a given file or image field array (`files.*`), a user-crafted malicious request could potentially bypass the validation rules.

Unexpected database bindings
This is a follow-up to the previous security advisory (GHSA-3p32-j457-pg5x) which addresses a few additional edge cases.

If a request is crafted where a field that is normally a non-array value is an array, and that input is not validated or cast to its expected type before being passed to the query builder, an unexpected number of query bindings can be added to the query. In some situations, this will simply lead to no results being returned by the query builder; however, it is possible certain queries could be affected in a way that causes the query to return unexpected results.

Unrestricted Upload of File with Dangerous Type
Laravel Framework does not sufficiently block the upload of executable PHP content because `Illuminate/Validation/Concerns/ValidatesAttributes.php` lacks a check for `.phar` files, which are handled as application/x-httpd-php on systems based on Debian. Note, this CVE Record is for Laravel Framework, and is unrelated to any reports concerning incorrectly written user applications for image upload.

Laravel RCE vulnerability in "cookie" session driver
Applications using the "cookie" session driver that were also exposing an encryption oracle via their application were vulnerable to remote code execution. An encryption oracle is a mechanism where arbitrary user input is encrypted and the encrypted string is later displayed or exposed to the user. This combination of scenarios lets the user generate valid Laravel signed encryption strings for any plain-text string, thus allowing them to craft Laravel session payloads when an application is using the "cookie" driver.

SQL Server LIMIT / OFFSET SQL Injection in laravel/framework and illuminate/database
### Impact

Those using SQL Server with Laravel and allowing user input to be passed directly to the `limit` and `offset` functions is vulnerable to SQL injection. Other database drivers such as MySQL and Postgres are not affected by this vulnerability.

### Patches

This problem has been patched on Laravel versions 6.20.26, 7.30.5, and 8.40.0.

### Workarounds

You may workaround this vulnerability by ensuring that only integers are passed to the `limit` and `offset` functions, as well as the `skip` and `take` functions.
