CVE-2026-28277 LangGraph: Unsafe msgpack deserialization in LangGraph checkpoint loading

LangGraph SQLite Checkpoint is an implementation of LangGraph CheckpointSaver that uses SQLite DB both sync and async, via aiosqlite. In version 1.0.9 and prior, LangGraph checkpointers can load msgpack-encoded checkpoints that reconstruct Python objects during deserialization. If an attacker can...

CVE-2026-28277

CVE-2026-28277 affects LangGraph checkpoint loading using an SQLite-backed checkpoint store. In versions ≤1.0.9, msgpack-encoded checkpoints may deserialize into Python objects, enabling an attacker with write access to the checkpoint store to craft payloads that trigger unsafe reconstruction whe...

SUSE CVE-2026-25899

Fiber is an Express inspired web framework written in Go. In versions on the v3 branch prior to 3.1.0, the use of the fiberflash cookie can force an unbounded allocation on any server. A crafted 10-character cookie value triggers an attempt to allocate up to 85GB of memory via unvalidated msgpack...

GHSA-2MR3-M5Q5-WGP6 Fiber is Vulnerable to Denial of Service via Flash Cookie Unbounded Allocation

Summary The use of the fiberflash cookie can force an unbounded allocation on any server. A crafted 10-character cookie value triggers an attempt to allocate up to 85GB of memory via unvalidated msgpack deserialization. No authentication is required. Every GoFiber v3 endpoint is affected regardle...

Fiber 安全漏洞

Fiber is an open-source web framework written in Go language. Versions of Fiber prior to 3.1.0 have a security vulnerability. This vulnerability stems from the fiberflash cookie, which can trigger excessive memory allocation through unvalidated msgpack deserialization, potentially leading to...
