In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, due to an error in convert.quoted-printable-decode filter certain data can lead to buffer overread by one byte, which can in certain circumstances lead to crashes or disclose content of other memory areas.

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, uncontrolled long string inputs to ldap_escape() function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write.

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, when using streams with configured proxy and "request_fulluri" option, the URI is not properly sanitized which can lead to HTTP request smuggling and allow the attacker to use the proxy to perform arbitrary HTTP requests originating from the server, thus potentially gaining access to resources not normally available to the external user.

The Custom CSS, JS & PHP plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg & remove_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.3.0. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, a hostile MySQL server can cause the client to disclose the content of its heap containing data from other SQL requests and possible other data belonging to different users of the same server.

In PHP versions 8.1.* before 8.1.31, 8.2.* before 8.2.26, 8.3.* before 8.3.14, uncontrolled long string inputs to ldap_escape() function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Yonatan Reinberg yPHPlista allows Stored XSS.This issue affects yPHPlista: from n/a through 1.1.1.

PhpSpreadsheet is a PHP library for reading and writing spreadsheet files. The `XmlScanner` class has a scan method which should prevent XXE attacks. However, in a bypass of the previously reported `CVE-2024-47873`, the regexes from the `findCharSet` method, which is used for determining the current encoding can be bypassed by using a payload in the encoding UTF-7, and adding at end of the file a comment with the value `encoding="UTF-8"` with `"`, which is matched by the first regex, so that `encoding='UTF-7'` with single quotes `'` in the XML header is not matched by the second regex. An attacker can bypass the sanitizer and achieve an XML external entity attack. Versions 1.9.4, 2.1.3, 2.3.2, and 3.4.0 fix the issue.

PhpSpreadsheet is a PHP library for reading and writing spreadsheet files. The XmlScanner class has a scan method which should prevent XXE attacks. However, prior to versions 1.9.4, 2.1.3, 2.3.2, and 3.4.0, the regexes used in the `scan` method and the findCharSet method can be bypassed by using UCS-4 and encoding guessing. An attacker can bypass the sanitizer and achieve an XML external entity attack. Versions 1.9.4, 2.1.3, 2.3.2, and 3.4.0 fix the issue.

phpIPAM version 1.5.1 contains a vulnerability where an attacker can bypass the IP block mechanism to brute force passwords for users by using the 'X-Forwarded-For' header. The issue lies in the 'get_user_ip()' function in 'class.Common.php' at lines 1044 and 1045, where the presence of the 'X-Forwarded-For' header is checked and used instead of 'REMOTE_ADDR'. This vulnerability allows attackers to perform brute force attacks on user accounts, including the admin account. The issue is fixed in version 1.7.0.
