Netty: [codec-http2] Lack of Host Header Deduplication in HTTP/2→HTTP/1.x Translation Leads to Request Routing Bypass

Netty's HTTP/2-to-HTTP/1.x translation layer Http2StreamFrameToHttpObjectCodec and InboundHttp2ToHttpAdapter fails to deduplicate or validate Host headers when an HTTP/2 client supplies both the :authority pseudo-header and a literal host header in a single HEADERS frame. The translator maps...

GHSA-4MP9-239F-G9HG Netty: WebSockets V07/V08 handshaker missing Connection/Upgrade validation

Summary An attacker can force WebSocket upgrade via the lax V07 or V08 handshaker by sending Sec-WebSocket-Version: 7 and omitting Connection: Upgrade / Upgrade: websocket headers, completing a protocol switch that a proxy would not recognize as an Upgrade request and enabling HTTP request...

CVE-2026-13089 OIDC::Lite versions through 0.12.1 for Perl allow ID Token signature verification bypass via a token-controlled algorithm allowlist in verify

OIDC::Lite versions through 0.12.1 for Perl allow ID Token signature verification bypass via a token-controlled algorithm allowlist in verify. When the caller does not pin an algorithm, OIDC::Lite::Model::IDToken::verify sets $self-alg$self-header-alg from the token's own header and then calls...

CVE-2026-14899

The code to parse MIME headers for display when forwarding a message if the setting to view all headers was enabled had an off-by-one error, allowing a single byte to be read from the memory after the buffer for the headers, and potentially crashing Thunderbird. This vulnerability was fixed in...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the rtpasffixheader function in libavformat/rtpdecasf.c. An attacker can exhaust CPU and prevent normal service by sending a crafted RTP/ASF stream containing ASF objects with a chunksize smaller than the 24-byte...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read through the spdifheaderdts4 function in libavformat/spdifenc.c. An attacker can read memory beyond the packet buffer by supplying a crafted DTS-HD stream with a coresize value larger than the actual packet length duri...
