CVE-2026-55858 MEDIUM POC PATCH GHSA This Month

Charset-confusion in MariaDB Connector/J (all branches prior to 2.7.14, 3.3.5, 3.4.3, and 3.5.9) allows a server-side character set change mid-session to silently decouple the driver's UTF-8 encoding assumption from the server's active encoding. Because the driver continues escaping SQL string literals as UTF-8 while the server parses incoming bytes under a different multi-byte encoding (e.g., GBK or BIG5), the mismatch can defeat byte-wise SQL quoting and enable SQL injection - a well-documented attack class for charset-confusion primitives. No public exploit has been identified and this CVE is not listed in CISA KEV at time of analysis.

CVE-2026-47079 LOW PATCH Monitor

Incorrect entity-passthrough logic in joshnuss xml_builder (Elixir) versions 0.0.6 through 2.4.0 allows attacker-supplied text containing pre-encoded entity sequences such as <script> to be emitted verbatim into serialized XML, rather than being double-encoded to <script>. When a downstream parser decodes the output and renders it in a markup-sensitive context - HTML, SVG, or RSS/Atom feeds - the entity sequences resolve into live markup, enabling content spoofing and cross-site scripting while bypassing upstream filters that block raw angle-bracket characters. No public exploit is identified at time of analysis, and no CISA KEV listing exists.
