CVE-2024-11236 1 Php 1 Php 2026-06-17 N/A 9.8 CRITICAL
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.
CVE-2024-11235 1 Php 1 Php 2026-06-17 N/A 8.1 HIGH
In PHP versions 8.3.* before 8.3.19 and 8.4.* before 8.4.5, a code sequence involving __set handler or ??=  operator and exceptions can lead to a use-after-free vulnerability. If the third party can control the memory layout leading to this, for example by supplying specially crafted inputs to the script, it could lead to remote code execution.
CVE-2024-11234 1 Php 1 Php 2026-06-17 N/A 4.8 MEDIUM
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.
CVE-2024-11233 1 Php 1 Php 2026-06-17 N/A 4.8 MEDIUM
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.
CVE-2023-3824 3 Debian, Fedoraproject, Php 3 Debian Linux, Fedora, Php 2026-06-17 N/A 9.4 CRITICAL
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.
CVE-2023-3823 3 Debian, Fedoraproject, Php 3 Debian Linux, Fedora, Php 2026-06-17 N/A 8.6 HIGH
In PHP versions 8.0.* before 8.0.30, 8.1.* before 8.1.22, and 8.2.* before 8.2.8 various XML functions rely on libxml global state to track configuration variables, like whether external entities are loaded. This state is assumed to be unchanged unless the user explicitly changes it by calling appropriate function. However, since the state is process-global, other modules - such as ImageMagick - may also use this library within the same process, and change that global state for their internal purposes, and leave it in a state where external entities loading is enabled. This can lead to the situation where external XML is parsed with external entities loaded, which can lead to disclosure of any local files accessible to PHP. This vulnerable state may persist in the same process across many requests, until the process is shut down.
CVE-2023-3247 1 Php 1 Php 2026-06-17 N/A 2.6 LOW
In PHP versions 8.0.* before 8.0.29, 8.1.* before 8.1.20, 8.2.* before 8.2.7 when using SOAP HTTP Digest Authentication, random value generator was not checked for failure, and was using narrower range of values than it should have. In case of random generator failure, it could lead to a disclosure of 31 bits of uninitialized memory from the client to the server, and it also made easier to a malicious server to guess the client's nonce. 
CVE-2023-0662 1 Php 1 Php 2026-06-17 N/A 7.5 HIGH
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, excessive number of parts in HTTP form upload can cause high resource consumption and excessive number of log entries. This can cause denial of service on the affected server by exhausting CPU resources or disk space.
CVE-2023-0568 1 Php 1 Php 2026-06-17 N/A 7.5 HIGH
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, core path resolution function allocate buffer one byte too small. When resolving paths with lengths close to system MAXPATHLEN setting, this may lead to the byte after the allocated buffer being overwritten with NUL value, which might lead to unauthorized data access or modification.
CVE-2022-4900 2 Php, Redhat 3 Php, Enterprise Linux, Software Collections 2026-06-17 N/A 6.2 MEDIUM
A vulnerability was found in PHP where setting the environment variable PHP_CLI_SERVER_WORKERS to a large value leads to a heap buffer overflow.
CVE-2022-37454 8 Debian, Extended Keccak Code Package Project, Fedoraproject and 5 more 8 Debian Linux, Extended Keccak Code Package, Fedora and 5 more 2026-06-17 N/A 9.8 CRITICAL
The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface.
CVE-2022-31631 2 Php, Sqlite 2 Php, Sqlite 2026-06-17 N/A 9.1 CRITICAL
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.
CVE-2022-31630 1 Php 1 Php 2026-06-17 N/A 6.5 MEDIUM
In PHP versions prior to 7.4.33, 8.0.25 and 8.1.12, when using imageloadfont() function in gd extension, it is possible to supply a specially crafted font file, such as if the loaded font is used with imagechar() function, the read outside allocated buffer will be used. This can lead to crashes or disclosure of confidential information. 
CVE-2022-31629 3 Debian, Fedoraproject, Php 3 Debian Linux, Fedora, Php 2026-06-17 N/A 6.5 MEDIUM
In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.
CVE-2022-31628 3 Debian, Fedoraproject, Php 3 Debian Linux, Fedora, Php 2026-06-17 N/A 2.3 LOW
In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the phar uncompressor code would recursively uncompress "quines" gzip files, resulting in an infinite loop.
CVE-2022-31627 1 Php 1 Php 2026-06-17 N/A 7.7 HIGH
In PHP versions 8.1.x below 8.1.8, when fileinfo functions, such as finfo_buffer, due to incorrect patch applied to the third party code from libmagic, incorrect function may be used to free allocated memory, which may lead to heap corruption.
CVE-2022-31626 2 Debian, Php 2 Debian Linux, Php 2026-06-17 6.0 MEDIUM 7.5 HIGH
In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when pdo_mysql extension with mysqlnd driver, if the third party is allowed to supply host to connect to and the password for the connection, password of excessive length can trigger a buffer overflow in PHP, which can lead to a remote code execution vulnerability.
CVE-2022-31625 2 Debian, Php 2 Debian Linux, Php 2026-06-17 6.8 MEDIUM 8.1 HIGH
In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of service.
