XSS within PHP-FPM status endpoint

In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, 8.5.* before 8.5.6, due to improper sanitation of user data, it allows an attacker to compose an URL, which will cause the target to execute arbitrary JavaScript code (XSS) on the target's machine when the target is viewing the PHP-FPM status page.

pgsql extension does not check for errors during escaping

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* pgsql and pdo_pgsql escaping functions do not check if the underlying quoting functions returned errors. This could cause crashes if Postgres server rejects the string as invalid.

Null byte termination in hostnames

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 some functions like fsockopen() lack validation that the hostname supplied does not contain null characters. This may lead to other functions like parse_url() treat the hostname in different way, thus opening way to security problems if the user code implements access checks before access using such functions.

NULL Pointer Dereference in PHP SOAP Extension via Large XML Namespace Prefix

In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 when parsing XML data in SOAP extensions, overly large (>2Gb) XML namespace prefix may lead to null pointer dereference. This may lead to crashes and affect the availability of the target server.

Stream HTTP wrapper truncates redirect location to 1024 bytes

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when parsing HTTP redirect in the response to an HTTP request, there is currently limit on the location value size caused by limited size of the location buffer to 1024. However as per RFC9110, the limit is recommended to be 8000. This may lead to incorrect URL truncation and redirecting to a wrong location.

Stream HTTP wrapper header check might omit basic auth header

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when user-supplied headers are sent, the insufficient validation of the end-of-line characters may prevent certain headers from being sent or lead to certain headers be misinterpreted.

Streams HTTP wrapper does not fail for headers with invalid name and no colon

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when receiving headers from HTTP server, the headers missing a colon (:) are treated as valid headers even though they are not. This may confuse applications into accepting invalid headers.

Header parser of http stream wrapper does not handle folded headers

In PHP from 8.1.* before 8.1.32, from 8.2.* before 8.2.28, from 8.3.* before 8.3.19, from 8.4.* before 8.4.5, when http request module parses HTTP response obtained from a server, folded headers are parsed incorrectly, which may lead to misinterpreting the response and using incorrect headers, MIME types, etc.

PDO::quote() may return unquoted string

In PHP versions 8.0.* before 8.0.27, 8.1.* before 8.1.15, 8.2.* before 8.2.2 when using PDO::quote() function to quote user-supplied data for SQLite, supplying an overly long string may cause the driver to incorrectly quote the data, which may further lead to SQL injection vulnerabilities.

Single byte overread with convert.quoted-printable-decode filter

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.

Configuring a proxy in a stream context might allow for CRLF injection in URIs

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.

Integer overflow in the firebird and dblib quoters causing OOB writes

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.

Leak partial content of the heap through heap buffer over-read in mysqlnd

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.

OOB access in ldap_escape

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.

cgi.force_redirect configuration is bypassable due to the environment variable collision

In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, HTTP_REDIRECT_STATUS variable is used to check whether or not CGI binary is being run by the HTTP server. However, in certain scenarios, the content of this variable can be controlled by the request submitter via HTTP headers, which can lead to cgi.force_redirect option not being correctly applied. In certain configurations this may lead to arbitrary file inclusion in PHP.

Erroneous parsing of multipart form data

In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, erroneous parsing of multipart form data contained in an HTTP POST request could lead to legitimate data not being processed. This could lead to malicious attacker able to control part of the submitted data being able to exclude portion of other data, potentially leading to erroneous application behavior.

Filter bypass in filter_var (FILTER_VALIDATE_URL)

In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error, filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of URLs the function will result in invalid user information (username + password part of URLs) being treated as valid user information. This may lead to the downstream code accepting invalid URLs as valid and parsing them incorrectly.

PHP function password_verify can erroneously return true when argument contains NUL

In PHP  version 8.1.* before 8.1.28, 8.2.* before 8.2.18, 8.3.* before 8.3.5, if a password stored with password_hash() starts with a null byte (\x00), testing a blank string as the password via password_verify() will incorrectly return true.

In PHP version 8.0.* before 8.0.30,  8.1.* before 8.1.22, and 8.2.* before 8.2.8, when loading phar file, while reading PHAR directory entries, insufficient length checking may lead to a stack buffer overflow, leading potentially to memory corruption or RCE.
