Tornado: Quadratic DoS via Crafted Multipart Parameters

Summary The parseparam function in Tornado's httputil.py is used to parse specific HTTP header values, such as those in multipart/form-data. This function uses an inefficient algorithm that repeatedly calls string.count within a nested loop while processing quoted semicolons e.g., param=";". As a...

IBM Langflow OSS path traversal vulnerability (CNVD-2026-31206)

IBM Langflow OSS is an open-source low-code visualization AI workflow building tool developed by IBM. It enables developers to quickly build, deploy, and iterate AI agents and RAG applications by dragging and dropping components. Additionally, it supports deep customization using Python to...

CVE-2026-8859

IBM Langflow OSS 1.0.0 through 1.10.0 Langflow could allow an attacker to write arbitrary files to unintended locations due to improper input validation in the APIRequest component. A path traversal vulnerability exists when the "Save to File" feature is enabled, where filenames extracted from HT...

CVE-2026-7667

IBM Langflow OSS 1.0.0 through 1.10.0 allows an authenticated attacker to create a malicious flow pointing to an attacker-controlled URL that returns a specially crafted Content-Disposition header e.g., filename="../../../target/path" , enabling arbitrary file write operations with...

CVE-2026-44974

CVE-2026-44974 affects the @hapi/content header parser. Before v6.0.2, Content.disposition() kept the last value for duplicate parameters while Content.type() kept the first for duplicate charset/boundary parameters, creating a parameter-smuggling primitive when duplicates are resolved inconsiste...

CVE-2026-44974 Parameter smuggling in @hapi/content header parser allows upload-filter bypass via duplicate parameters

@hapi/content provided HTTP Content- headers parsing. Prior to 6.0.2, Content.disposition retained the last occurrence of each duplicate parameter while Content.type retained the first occurrence of duplicate charset and boundary parameters, creating a parameter-smuggling primitive when another...
