CVE-2026-69205 Http4s: Ember Transfer-Encoding value parsing (TE.CL / TE.0 request smuggling)

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, Ember’s HeaderP.parse uses a case-sensitive substring test for the Transfer-Encoding value and decodes header bytes with the platform default charset. Values such as Chunked are not recognized, values such as notchunke...

CVE-2026-69205

Http4s (a Scala HTTP library) is affected in its Ember backend, specifically the HeaderP.parse function, which uses a case-sensitive substring test for the Transfer-Encoding value and decodes header bytes with the platform default charset. This causes mismatches with RFC-compliant intermediaries,...

CVE-2026-55859

MariaDB Connector/R2DBC is a non-blocking MariaDB and MySQL client implemented in Java. Prior to 1.4.1, org.mariadb:r2dbc-mariadb encodes and decodes all character data under the assumption that the connection character set is UTF-8. A server can announce a mid-session change to charactersetclien...

CVE-2026-55855

MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.4, 3.3.3, 3.4.6, and 3.5.3, MariaDB Connector/Node.js permits SQL injection when attacker-controlled Buffer parameters are escaped client-side under the big5, gbk, sjis,...

GHSA-G5XC-5W98-JFVM MariaDB has possible SQL injection in Buffer parameter escaping under big5/gbk/sjis/cp932/gb18030 client charsets

Summary A SQL injection is possible when the connector escapes Buffer parameters client-side under a multi-byte client character set whose trail-byte range overlaps the ASCII backslash 0x5C: big5, gbk, sjis, cp932, and gb18030. Under these charsets, an attacker-controlled lead byte can absorb the...
