CVE-2026-27794

A flaw was found in LangGraph Checkpoint. This vulnerability allows a remote attacker with write access to the cache backend to achieve remote code execution. This occurs when applications enable cache backends that inherit from BaseCache and opt nodes into caching via CachePolicy. If msgpack...

c3p0 vulnerable to Remote Code Execution via unsafe deserialization of userOverridesAsString property

Impact c3p0 is vulnerable to attack via maliciously crafted Java-serialized objects and javax.naming.Reference instances. Several c3p0 ConnectionPoolDataSource implementations have a property called userOverridesAsString which conceptually represents a Map. Prior to v0.12.0, that property was...
