BIT-LIBPHP-2026-6104 Global buffer over-read in mb_convert_encoding() with attacker-supplied encoding

In PHP versions 8.4. before 8.4.21 and 8.5. before 8.5.6, when an encoding name containing an embedded NUL byte is passed to mbconvertencoding or related mbstring functions, the code incorrectly assumes that when strncasecmp returns 0 it means the strings have the same length. This can lead to...

BIT-LIBPHP-2025-14179 SQL injection in pdo_firebird via NUL bytes in quoted strings

In PHP versions 8.2. before 8.2.31, 8.3. before 8.3.31, 8.4. before 8.4.21, and 8.5. before 8.5.6, the PDO Firebird driver improperly handles NUL bytes when preparing SQL queries. During token-by-token query construction, a string token containing a NUL byte is copied via strncat, which stops at...
