The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a one byte over-read in streams when using the convert.quoted-printable-decode filter. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


3) CRLF injection (CVE-ID: CVE-2024-11234)

CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of URIs in streams component when using proxy. A remote attacker can pass specially crafted data to the application containing CR-LF characters and perform a spoofing attack.


4) Input validation error (CVE-ID: CVE-2025-1217)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to Header parser of HTTP Stream wrapper does not handle folded headers. A remote attacker can perform spoofing attack by manipulating HTTP headers.


5) Improper Authentication (CVE-ID: CVE-2025-1736)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in Stream HTTP wrapper header check, which can omit Basic authentication header. A remote attacker can bypass authentication mechanisms that rely on Basic authentication.


6) Input validation error (CVE-ID: CVE-2025-1734)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to the Streams HTTP wrapper does not fail for headers without a colon. A remote attacker can potentially perform header injection, which can lead to a spoofing attack.


7) Resource management error (CVE-ID: CVE-2025-1219)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists in libxml streams due to usage of an incorrect Content-Type header when requesting a redirected resource. A remote attacker can leverage this vulnerability to perform content spoofing or XSS attacks.


8) Input validation error (CVE-ID: CVE-2025-1861)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to redirect the application to a malicious URL.

The vulnerability exists due to insufficient validation of user-supplied input. The Stream HTTP wrapper truncates redirect location to 1024 bytes, which can lead to the application being redirected to a wrong URL.


9) Improper error handling (CVE-ID: CVE-2025-1735)

CWE-ID: CWE-388 - Error Handling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect handling of error messages and situations in pgsql extension. A remote attacker can pass specially crafted data to the application and perform a denial of service attack under certain circumstances. 


10) NULL pointer dereference (CVE-ID: CVE-2025-6491)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the PHP SOAP extension. A remote attacker can pass a large XML namespace prefix to the application and perform a denial of service (DoS) attack.


11) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-1220)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:L/SI:L/SA:N/E:U/U:Green


The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of the null byte in the fsockopen() function implementation when handling hostnames. A remote attacker can pass a specially crafted hostname to the application and force it to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.


12) Heap-based buffer overflow (CVE-ID: CVE-2025-14178)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the array_merge() PPH function. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


13) Memory leak (CVE-ID: CVE-2025-14177)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform DoS attack on the target system.
