CVE-2026-59990: Allocation of Resources Without Limits or Throttling

Jawn is an open source JSON parser. Prior to 1.7.0, Jawn parse methods accept arbitrarily deep JSON array and object nesting without a depth limit, allowing a remote attacker who can submit untrusted JSON to grow parser contexts until the JVM heap is exhausted. The resulting...

SUSE CVE-2026-93488

A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAXVALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYNSTREAM...

com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...

com.github.luben/zstd-jni: zstd-jni: Denial of Service via out-of-bounds read in ZstdDictDecompress

A flaw was found in zstd-jni. This vulnerability, an out-of-bounds read, occurs in the ZstdDictDecompress constructor due to insufficient validation of offset and length arguments against dictionary array bounds. A remote attacker could exploit this by providing specially crafted input, leading t...

com.github.luben/zstd-jni: zstd-jni: Denial of Service (DoS) via out-of-bounds read in Zstd.trainFromBufferDirect

A flaw was found in zstd-jni. Attackers can exploit this by supplying oversized per-sample lengths to the Zstd.trainFromBufferDirect function, which fails to validate the samples buffer capacity. This allows for reading past buffer boundaries, leading to out-of-bounds memory access and ultimately...
