CVE-2026-87824

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...

CVE-2025-27533-Exploit-for-Apache-ActiveMQ PoC exploit for CVE-2025-27533 , a Denial of Service DoS vulnerability in Apache ActiveMQ. This tool sends malicious OpenWire packets to exhaust the JVM heap memory of the target server, and potentially crashing the ActiveMQ service on port 61616. USE...

CVE-2026-87825

A flaw was found in zstd-jni. This use-after-free vulnerability occurs because streams and contexts only hold a dictionary's shared lock during the load call, allowing the dictionary to be closed while still being referenced. A remote attacker could exploit this by closing a dictionary after...

Log4jHotPatch This is a tool which injects a Java agent into a running JVM process. The agent will attempt to patch the lookup method of all loaded org.apache.logging.log4j.core.lookup.JndiLookup instances to unconditionally return the string "Patched JndiLookup::lookup". It is designed to addres...

CVE-2026-87877

zstd-jni versions before 1.5.7-14 fail to validate closed state in setDict, setLongMax, setLevel and setRefMultipleDDicts methods of stream classes. Attackers can call these methods on closed streams to write through freed native pointers, corrupting unrelated objects or crashing the JVM...

CVE-2026-87823

zstd-jni before 1.5.7-14 performs 32-bit signed bounds checks on three direct-ByteBuffer frame-size native methods, allowing out-of-bounds memory reads via negative or overflowing offsets. Attackers can supply negative offset values near Integer.MINVALUE to read unmapped memory, causing JVM...

CVE-2026-87824

zstd-jni before 1.5.7-14 fails to validate the samples buffer capacity in Zstd.trainFromBufferDirect, allowing attackers to read past buffer boundaries by supplying oversized per-sample lengths. Attackers can trigger out-of-bounds memory access by providing crafted sample length arrays that cause...

CVE-2026-87825

zstd-jni before 1.5.7-14 contains a use-after-free vulnerability where streams and contexts hold a dictionary's shared lock only during the load call, allowing the dictionary to be closed while still referenced. Attackers can close a dictionary after associating it with a stream or context, causi...

CVE-2026-87877

zstd-jni versions 1.3.8-4 through 1.5.7-13 are vulnerable to a use-after-free in stream classes. The root cause is a failure to validate the closed state in the setDict, setLongMax, setLevel, and setRefMultipleDDicts methods, allowing callers to write through freed native pointers on already-clos...

CVE-2026-87824

zstd-jni (Java binding for the zstd compression library) versions 1.3.3-1 through 1.5.7-13 contain an out-of-bounds read vulnerability in the Zstd.trainFromBufferDirect method. The root cause is a failure to validate the samples buffer capacity in the native implementation (jni_zdict.c): an attac...
