CVE-2026-91769
PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN w...
UBUNTU-CVE-2026-17545
On Windows, PHP's filesystem and stream APIs do not reject reserved device names such as CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9, CONIN$ and CONOUT$ when they appear as a component of a path. An attacker-controlled filename therefore reaches CreateFileW and opens a device instead of the...

CVE-2026-91767
A flaw was found in PHP. When validating secure connections using Transport Layer Security TLS, an error in how wildcard domain names in server certificates are verified can lead to an out-of-bounds memory read. A malicious server presenting a specially crafted certificate can exploit this issue...
CVE-2026-91766
A flaw was found in PHP. When following a redirect, the built-in HTTP Hypertext Transfer Protocol stream wrapper forwards sensitive request headers—such as authentication tokens and session cookies—unchanged, even when directed to a different host, port, or unencrypted connection. A malicious...
CVE-2026-17545
A flaw was found in PHP. When running on Windows environments, PHP's filesystem and stream handlers fail to reject reserved system device names in file paths. An attacker who can control file or stream paths can supply these reserved names to open system devices instead of standard files. This ca...
CVE-2026-91765
A flaw was found in PHP. An unauthenticated remote attacker could cause a Denial of Service DoS by sending a specially crafted request to an affected Simple Object Access Protocol SOAP server endpoint. Due to a lack of recursion depth limits when parsing deeply nested XML elements, processing suc...
CVE-2026-92842
The convert.base64-encode, convert.quoted-printable-encode and convert.quoted-printable-decode stream filters accept a line-break-chars option whose length is tracked separately from the string itself. The filter constructors duplicate the value with pestrdup, which stops at the first NUL byte,...
CVE-2025-1218
A flaw was found in PHP. The MySQL Native Driver mysqlnd wire protocol parser fails to verify that an incoming packet contains enough bytes before reading its fields. A malicious or compromised database server can send a truncated packet, causing the client application to read past the buffer...
CVE-2026-6103
A flaw was found in PHP. An integer overflow vulnerability in the Phar extension occurs when parsing TAR archive headers containing excessively large size fields. An attacker can exploit this issue by supplying a specially crafted archive file to an application that processes TAR archives, causin...
CVE-2026-91769
PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN w...
CVE-2026-91769 TLS Hostname Verification Falls Back to CN After SAN Mismatch
PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN w...
CVE-2026-91769
A flaw exists in PHP 's OpenSSL stream peer verification where the system improperly falls back to the Common Name (CN) if no Subject Alternative Name (SAN) matches the requested hostname. This violates RFC 6125 , as the CN should be ignored when service identities are present. An attacker could ...
