CVE-2024-2757 1 Php 1 Php 2025-06-18 N/A 7.5 HIGH
In PHP 8.3.* before 8.3.5, function mb_encode_mimeheader() runs endlessly for some inputs that contain long strings of non-space characters followed by a space. This could lead to a potential DoS attack if a hostile user sends data to an application that uses this function.
CVE-2024-3096 2 Debian, Php 2 Debian Linux, Php 2025-06-18 N/A 6.5 MEDIUM
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.
CVE-2025-1219 1 Php 1 Php 2025-05-23 N/A 5.3 MEDIUM
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 requesting a HTTP resource using the DOM or SimpleXML extensions, the wrong content-type header is used to determine the charset when the requested resource performs a redirect. This may cause the resulting document to be parsed incorrectly or bypass validations.
CVE-2025-1217 1 Php 1 Php 2025-05-23 N/A 3.1 LOW
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.
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 2025-05-08 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-2024-11235 1 Php 1 Php 2025-04-30 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-2015-8994 1 Php 1 Php 2025-04-20 6.8 MEDIUM 7.5 HIGH
An issue was discovered in PHP 5.x and 7.x, when the configuration uses apache2handler/mod_php or php-fpm with OpCache enabled. With 5.x after 5.6.28 or 7.x after 7.0.13, the issue is resolved in a non-default configuration with the opcache.validate_permission=1 setting. The vulnerability details are as follows. In PHP SAPIs where PHP interpreters share a common parent process, Zend OpCache creates a shared memory object owned by the common parent during initialization. Child PHP processes inherit the SHM descriptor, using it to cache and retrieve compiled script bytecode ("opcode" in PHP jargon). Cache keys vary depending on configuration, but filename is a central key component, and compiled opcode can generally be run if a script's filename is known or can be guessed. Many common shared-hosting configurations change EUID in child processes to enforce privilege separation among hosted users (for example using mod_ruid2 for the Apache HTTP Server, or php-fpm user settings). In these scenarios, the default Zend OpCache behavior defeats script file permissions by sharing a single SHM cache among all child PHP processes. PHP scripts often contain sensitive information: Think of CMS configurations where reading or running another user's script usually means gaining privileges to the CMS database.
CVE-2017-12934 1 Php 1 Php 2025-04-20 5.0 MEDIUM 7.5 HIGH
ext/standard/var_unserializer.re in PHP 7.0.x before 7.0.21 and 7.1.x before 7.1.7 is prone to a heap use after free while unserializing untrusted data, related to the zval_get_type function in Zend/zend_types.h. Exploitation of this issue can have an unspecified impact on the integrity of PHP.
CVE-2017-11362 1 Php 1 Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
In PHP 7.x before 7.0.21 and 7.1.x before 7.1.7, ext/intl/msgformat/msgformat_parse.c does not restrict the locale length, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact within International Components for Unicode (ICU) for C/C++ via a long first argument to the msgfmt_parse_message function.
CVE-2016-7479 1 Php 1 Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
In all versions of PHP 7, during the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain arbitrary code execution.
CVE-2017-12868 2 Php, Simplesamlphp 2 Php, Simplesamlphp 2025-04-20 7.5 HIGH 9.8 CRITICAL
The secureCompare method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.13 and earlier, when used with PHP before 5.6, allows attackers to conduct session fixation attacks or possibly bypass authentication by leveraging missing character conversions before an XOR operation.
CVE-2016-5399 1 Php 1 Php 2025-04-20 6.8 MEDIUM 7.8 HIGH
The bzread function in ext/bz2/bz2.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted bz2 archive.
CVE-2017-11142 1 Php 1 Php 2025-04-20 7.8 HIGH 7.5 HIGH
In PHP before 5.6.31, 7.x before 7.0.17, and 7.1.x before 7.1.3, remote attackers could cause a CPU consumption denial of service attack by injecting long form variables, related to main/php_variables.c.
CVE-2017-9227 2 Oniguruma Project, Php 2 Oniguruma, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching. Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer.
CVE-2017-9224 2 Oniguruma Project, Php 2 Oniguruma, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer.
CVE-2017-9226 2 Oniguruma Project, Php 2 Oniguruma, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption.
CVE-2017-9067 2 Modx, Php 2 Modx Revolution, Php 2025-04-20 4.4 MEDIUM 7.0 HIGH
In MODX Revolution before 2.5.7, when PHP 5.3.3 is used, an attacker is able to include and execute arbitrary files on the web server due to insufficient validation of the action parameter to setup/index.php, aka directory traversal.
CVE-2017-5630 1 Php 1 Pear 2025-04-20 5.0 MEDIUM 7.5 HIGH
PECL in the download utility class in the Installer in PEAR Base System v1.10.1 does not validate file types and filenames after a redirect, which allows remote HTTP servers to overwrite files via crafted responses, as demonstrated by a .htaccess overwrite.
CVE-2017-9119 2 Netapp, Php 3 Clustered Data Ontap, Storage Automation Store, Php 2025-04-20 7.5 HIGH 9.8 CRITICAL
The i_zval_ptr_dtor function in Zend/zend_variables.h in PHP 7.1.5 allows attackers to cause a denial of service (memory consumption and application crash) or possibly have unspecified other impact by triggering crafted operations on array data structures.
CVE-2016-5873 1 Php 1 Pecl Http 2025-04-20 7.5 HIGH 9.8 CRITICAL
Buffer overflow in the HTTP URL parsing functions in pecl_http before 3.0.1 might allow remote attackers to execute arbitrary code via non-printable characters in a URL.
