JLSEC-2026-624 HTTP/2 client HPACK desynchronization via header blocks for unknown streams in HTTP.jl

Description The HTTP/2 client's processincomingframe! dropped HEADERS/CONTINUATION frames for stream ids absent from conn.streams without passing the header block through the connection's HPACK decoder. Because HPACK's dynamic table is connection-scoped and mutated as a side effect of decoding ea...

CVE-2026-55603

CVE-2026-55603 affects http-proxy-middleware (Node.js). In versions 3.0.4–3.0.7 and 4.1.1, fixRequestBody() rebuilds multipart/form-data by interpolating req.body into the wire format without neutralizing CR/LF. This can let an attacker inject a new multipart part (via unescaped CRLF in keys/valu...

CVE-2026-53655

node-tar (node-tar) before version 7.5.16 is vulnerable: it applies a PAX extended header size override to the next header entry, including intermediary L/K/x headers, which desynchronizes the stream cursor from other tar implementations. This yields a tar-parser interpretation differential (CWE-...
