#	CVE ID	CWE ID	Vulnerability Type(s)	Publish Date	Update Date	Score	Gained Access Level	Access	Complexity	Authentication	Conf.	Integ.	Avail.
1	CVE-2021-21707			2021-11-29	2023-02-16	5.0	None	Remote	Low	Not required	Partial	None	None
In PHP versions 7.3.x below 7.3.33, 7.4.x below 7.4.26 and 8.0.x below 8.0.13, certain XML parsing functions, like simplexml_load_file(), URL-decode the filename passed to them. If that filename contains URL-encoded NUL character, this may cause the function to interpret this as the end of the filename, thus interpreting the filename differently from what the user intended, which may lead it to reading a different file than intended.
2	CVE-2021-21705	20		2021-10-04	2022-10-29	5.0	None	Remote	Low	Not required	None	Partial	None
In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using URL validation functionality via filter_var() function with FILTER_VALIDATE_URL parameter, an URL with invalid password field can be accepted as valid. This can lead to the code incorrectly parsing the URL and potentially leading to other security implications - like contacting a wrong server or making a wrong access decision.
3	CVE-2021-21702	476		2021-02-15	2021-12-10	5.0	None	Remote	Low	Not required	None	None	Partial
In PHP versions 7.3.x below 7.3.27, 7.4.x below 7.4.15 and 8.0.x below 8.0.2, when using SOAP extension to connect to a SOAP server, a malicious SOAP server could return malformed XML data as a response that would cause PHP to access a null pointer and thus cause a crash.
4	CVE-2020-7071	20		2021-02-15	2022-08-29	5.0	None	Remote	Low	Not required	None	Partial	None
In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14 and 8.0.0, when validating URL with functions like filter_var($url, FILTER_VALIDATE_URL), PHP will accept an URL with invalid password as valid URL. This may lead to functions that rely on URL being valid to mis-parse the URL and produce wrong data as components of the URL.
5	CVE-2020-7070	565		2020-10-02	2021-12-02	5.0	None	Remote	Low	Not required	None	Partial	None
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-8184 for more information.
6	CVE-2020-7067	125		2020-04-27	2022-05-16	5.0	None	Remote	Low	Not required	Partial	None	None
In PHP versions 7.2.x below 7.2.30, 7.3.x below 7.3.17 and 7.4.x below 7.4.5, if PHP is compiled with EBCDIC support (uncommon), urldecode() function can be made to access locations past the allocated memory, due to erroneously using signed numbers as array indexes.
7	CVE-2020-7064	125		2020-04-01	2022-08-29	5.8	None	Remote	Medium	Not required	Partial	None	Partial
In PHP versions 7.2.x below 7.2.9, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while parsing EXIF data with exif_read_data() function, it is possible for malicious data to cause PHP to read one byte of uninitialized memory. This could potentially lead to information disclosure or crash.
8	CVE-2020-7063	281		2020-02-27	2022-05-08	5.0	None	Remote	Low	Not required	None	Partial	None
In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all access) even if the original files on the filesystem were with more restrictive permissions. This may result in files having more lax permissions than intended when such archive is extracted.
9	CVE-2019-19246	125		2019-11-25	2022-08-29	5.0	None	Remote	Low	Not required	None	None	Partial

In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18 and 7.4.x below 7.4.6, when HTTP file uploads are allowed, supplying overly long filenames or field names could lead PHP engine to try to allocate oversized memory storage, hit the memory limit and stop processing the request, without cleaning up temporary files created by upload request. This potentially could lead to accumulation of uncleaned temporary files exhausting the disk space on the target server.
11	CVE-2019-11046	125		2019-12-23	2022-12-20	5.0	None	Remote	Low	Not required	Partial	None	None
In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations.
12	CVE-2019-11044			2019-12-23	2022-12-14	5.0	None	Remote	Low	Not required	Partial	None	None
In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 on Windows, PHP link() function 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.
13	CVE-2019-11042	125		2019-08-09	2023-02-28	5.8	None	Remote	Medium	Not required	Partial	None	Partial

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 SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition.
37	CVE-2017-9118	125		2018-08-02	2022-08-29	5.0	None	Remote	Low	Not required	None	None	Partial
PHP 7.1.5 has an Out of bounds access in php_pcre_replace_impl via a crafted preg_replace call.
38	CVE-2017-7963	770	DoS	2017-04-19	2019-10-03	5.0	None	Remote	Low	Not required	None	None	Partial
DISPUTED The GNU Multiple Precision Arithmetic Library (GMP) interfaces for PHP through 7.1.4 allow attackers to cause a denial of service (memory consumption and application crash) via operations on long strings. NOTE: the vendor disputes this, stating "There is no security issue here, because GMP safely aborts in case of an OOM condition. The only attack vector here is denial of service. However, if you allow attacker-controlled, unbounded allocations you have a DoS vector regardless of GMP's OOM behavior."
39	CVE-2017-7272	918		2017-03-27	2018-02-26	5.8	None	Remote	Medium	Not required	Partial	Partial	None
PHP through 7.1.11 enables potential SSRF in applications that accept an fsockopen or pfsockopen hostname argument with an expectation that the port number is constrained. Because a :port syntax is recognized, fsockopen will use the port number that is specified in the hostname argument, instead of the port number in the second argument of the function.
40	CVE-2017-7189	20		2019-07-10	2019-07-17	5.0	None	Remote	Low	Not required	Partial	None	None
main/streams/xp_socket.c in PHP 7.x before 2017-03-07 misparses fsockopen calls, such as by interpreting fsockopen('127.0.0.1:80', 443) as if the address/port were 127.0.0.1:80:443, which is later truncated to 127.0.0.1:80. This behavior has a security risk if the explicitly provided port number (i.e., 443 in this example) is hardcoded into an application as a security policy, but the hostname argument (i.e., 127.0.0.1:80 in this example) is obtained from untrusted input.
41	CVE-2017-6441	476	DoS	2017-04-03	2017-04-10	5.0	None	Remote	Low	Not required	None	None	Partial
DISPUTED The _zval_get_long_func_ex in Zend/zend_operators.c in PHP 7.1.2 allows attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted use of "declare(ticks=" in a PHP script. NOTE: the vendor disputes the classification of this as a vulnerability, stating "Please do not request CVEs for ordinary bugs. CVEs are relevant for security issues only."
42	CVE-2016-10712	20		2018-02-09	2019-05-22	5.0	None	Remote	Low	Not required	None	Partial	None
