LLM-Guided Prompt Evolution for Password Guessing

Passwords still remain a dominant authentication method, yet their security is routinely subverted by predictable user choices and large-scale credential leaks. Automated password guessing is a key tool for stress-testing password policies and modeling attacker behavior. This paper applies...

PT-2026-34828

Impact A crafted hostAlias argument such as -oProxyCommand=... was passed to ssh/scp without an argument terminator. SSH interprets arguments starting with - as options regardless of position, so the option-injection caused SSH to execute the attacker-supplied ProxyCommand locally on the machine...

CVE-2026-40087

A flaw was found in LangChain. A missing validation of f-string prompt templates in some classes, specifically in DictPromptTemplate and ImagePromptTemplate, can cause the evaluation of attribute access or indexing expressions during template formatting. Also, f-string validation based on parsed...

PraisonAIAgents: Arbitrary File Read via read_skill_file Missing Workspace Boundary and Approval Gate

Summary readskillfile in skilltools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skillpath parameter. Unlike filetools.readfile which enforces workspace boundary confinement, and unlike runskillscript which requires critical-level approval, readskillfile has...

CLIP-Inspector: Model-Level Backdoor Detection for Prompt-Tuned CLIP Via OOD Trigger Inversion

Organisations with limited data and computational resources increasingly outsource model training to Machine Learning as a Service MLaaS providers, who adapt vision-language models VLMs such as CLIP to downstream tasks via prompt tuning rather than training from scratch. This semi-honest setting...

PT-2026-33895

Summary The approval system in PraisonAI Agents caches tool approval decisions by tool name only, not by invocation arguments. Once a user approves execute command for any command e.g., ls -la, all subsequent execute command calls in that execution context bypass the approval prompt entirely...

Anthropic Claude Code < 2.0.65 API Key Leak via Project Settings (CVE-2026-21852)

The version of Anthropic Claude Code installed on the remote host is prior to 2.0.65. It is, therefore, affected by an information disclosure vulnerability. A vulnerability in the project-load flow allowed malicious repositories to exfiltrate data including Anthropic API keys before users confirm...

CVE-2026-40111

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, he memory hooks executor in praisonaiagents passes a user-controlled command string directly to subprocess.run with shell=True at src/praisonai-agents/praisonaiagents/memory/hooks.py. No sanitization is performed and shell...

CVE-2026-40111

PraisonAIAgents memory/hooks.py allows OS command injection via a user-controlled string passed to subprocess.run() with shell=True before 1.5.128. No sanitization occurs, shell metacharacters are interpreted by /bin/sh, enabling execution of arbitrary commands. Two attack surfaces exist: pre_run...
