js-yaml: js-yaml: Denial of Service via crafted YAML ordered-map document

A flaw was found in js-yaml, a JavaScript YAML YAML Ain't Markup Language parser. An attacker could exploit this by providing a specially crafted YAML ordered-map document. This could lead to excessive CPU consumption, resulting in a denial of service DoS for applications processing the malicious...

js-yaml: js-yaml: Denial of Service via quadratic CPU time parsing with merge keys

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. When merge keys are enabled, a remote attacker could exploit this vulnerability by crafting a YAML document where a chain of mappings uses merge keys, each merging the previous one. This can lead to a significant increase in CPU ti...

openSUSE 16 Security Update : python-pytest-html (openSUSE-SU-2026:21176-1)

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21176-1 advisory. Changes in python-pytest-html: - Revendor updating shell-quote and js-yaml deps: - CVE-2026-13311: shell-quote: inefficient input parsing can le...

CVE-2026-54074

Tina is a headless content management system. @tinacms/cli versions prior to 2.4.3 contain a Remote Code Execution vulnerability in the Forestry-to-Tina migration command. The internal helper addVariablesToCode unquotes any value matching the marker "TINAINTERNAL:::.?:::" inside the stringified...

js-yaml: js-yaml: Denial of Service via crafted YAML merge keys

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker can exploit this vulnerability by providing a specially crafted YAML document that repeatedly uses the same alias in a merge sequence. This can lead to algorithmic CPU exhaustion, causing the Node.js worker or eve...

CVE-2026-49451

The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. From 2.0.0-preview11 until 2.7.5 and 3.5.4, a small OpenAPI document containing a circular schema reference can cause proce...

CVE-2026-49451

The issue affects the OpenAPI.NET SDK used for OpenAPI document parsing in .NET. A circular schema reference in a small OpenAPI document can cause process termination via stack overflow when using public OpenAPI.NET reader APIs, applicable to both JSON and YAML paths. Affected versions range from...

Microsoft.OpenAPI: Circular schema references may terminate OpenAPI parsing

Impact A small OpenAPI document containing a circular schema reference can cause process termination through stack overflow in Microsoft.OpenApi. The issue affects OpenAPI document parsing through public OpenAPI.NET reader APIs and has been confirmed across both JSON and YAML reader paths. Affect...

This update for python-pytest-html fixes the following issues: Changes in python-pytest-html: - Revendor updating shell-quote and js-yaml deps: - CVE-2026-13311: shell-quote: inefficient input parsing can lead to a denial of service bsc1269361 - CVE-2026-53550: js-yaml: quadratic complexity when...

PYSEC-2026-362 Jupyter Enterprise Gateway: Kubernetes Manifest Injection in Jinja2 Template Rendering

Summary The environment variables used during the rendering of the Kubernetes manifest allow YAML injection, enabling attackers to overwrite existing keys like securityContext and inject multi-document YAML to create additional unintended Kubernetes resources. Details The server interpolates...

PYSEC-2026-461 PraisonAI Vulnerable to OS Command Injection

The executecommand function and workflow shell execution are exposed to user-controlled input via agent workflows, YAML definitions, and LLM-generated tool calls, allowing attackers to inject arbitrary shell commands through shell metacharacters. --- Description PraisonAI's workflow system and...

PYSEC-2026-462 PraisonAI Vulnerable to Remote Code Execution via YAML Deserialization in Agent Definition Loading

Summary The AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed, executes arbitrary JavaScript code. An attacker can...

PYSEC-2026-488 PraisonAI has critical RCE via `type: job` workflow YAML

praisonai workflow run loads untrusted YAML and if type: job executes steps through JobWorkflowExecutor in jobworkflow.py. This supports: - run: → shell command execution via subprocess.run - script: → inline Python execution via exec - python: → arbitrary Python script execution A malicious YAML...

PYSEC-2026-402 Remote Code Execution via path traversal bypass in lollms

CVE-2024-4320 describes a vulnerability in the parisneo/lollms software, specifically within the ExtensionBuilder.buildextension function. The vulnerability arises from the /mountextension endpoint, where a path traversal issue allows attackers to navigate beyond the intended directory structure...

PYSEC-2026-393 Unsafe yaml deserialization in llama-hub
