PYSEC-2026-1429 GuardDog Zip Bomb Vulnerability in safe_extract() Allows DoS

Summary GuardDog's safeextract function does not validate decompressed file sizes when extracting ZIP archives wheels, eggs, allowing attackers to cause denial of service through zip bombs. A malicious package can consume gigabytes of disk space from a few megabytes of compressed data...

PYSEC-2026-1553 Litestar X-Forwarded-For Header Spoofing Vulnerability Enables Rate Limit Evasion

While testing Litestar's RateLimitMiddleware, I discovered that rate limits can be completely bypassed by manipulating the X-Forwarded-For header. This renders IP-based rate limiting ineffective against determined attackers. The Problem Litestar's RateLimitMiddleware uses cachekeyfromrequest to...

Fides has a Lack of Brute-Force Protections on Authentication Endpoints

SummaryThe Fides Admin UI login endpoint relies on a general IP-based rate limit for all API traffic and lacks specific anti-automation controls designed to protect against brute-force attacks. This could allow attackers to conduct credential testing attacks, such as credential stuffing or passwo...

PYSEC-2026-1608 MaterialX Lack of MTLX Import Depth Limit Leads to DoS (Denial-Of-Service) Via Stack Exhaustion

Summary Nested imports of MaterialX files can lead to a crash via stack memory exhaustion, due to the lack of a limit on the "import chain" depth. Details The MaterialX specification supports importing other files by using XInclude tags. When parsing file imports, recursion is used to process...

protobuf-python has a potential Denial of Service issue

SummaryAny project that uses Protobuf pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUP tags can be corrupted by exceeding the Python recursion limit.Reporter: Alexis Challande, Trail of Bits...

CVE-2026-56811 Phoenix transports do not limit channel joins per connection, enabling process-exhaustion denial of service

Allocation of Resources Without Limits or Throttling vulnerability in phoenixframework phoenix Phoenix.Socket module allows an unauthenticated attacker to cause a denial of service against any endpoint that mounts a Phoenix socket with a reachable channel transport WebSocket or LongPoll. This...

CVE-2026-56811

The CVE-2026-56811 issue affects the Phoenix framework (Phoenix.Socket) where transports (WebSocket/LongPoll) allow an unbounded number of channel joins per transport, enabling a single unauthenticated client to exhaust BEAM processes and cause a denial-of-service across the node. Root cause is l...

Aim Uncontrolled Resource Consumption vulnerability

A vulnerability in aimhubio/aim version 3.25.0 allows for a denial of service DoS attack. The issue arises when a large number of tracked metrics are retrieved simultaneously from the Aim web API, causing the web server to become unresponsive. The root cause is the lack of a limit on the number o...

Synapse allows unsupported content types to lead to memory exhaustion

ImpactIn Synapse before 1.120.1, multipart/form-data requests can in certain configurations transiently increase memory consumption beyond expected levels while processing the request, which can be used to amplify denial of service attacks. PatchesSynapse 1.120.1 resolves the issue by denying...

Litestar allows unbounded resource consumption (DoS vulnerability)
