Laravel allows environment manipulation via query string

Laravel is a web application framework. 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. The vulnerability fixed in 6.20.45, 7.30.7, 8.83.28, 9.52.17, 10.48.23, and 11.31.0. The framework now ignores argv values for environment detection on non-cli SAPIs.

DirectoryIterator class silently truncates after a null byte

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access.

get_headers() silently truncates after a null byte

In PHP versions 7.2.x below 7.2.29, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using get_headers() with user-supplied URL, if the URL contains zero (\0) character, the URL will be silently truncated at it. This may cause some software to make incorrect assumptions about the target of the get_headers() and possibly send some information to a wrong server.
