CVE-2026-40153 (GCVE-0-2026-40153)

Vulnerability from nvd – Published: 2026-04-09 21:27 – Updated: 2026-04-09 21:27

Title

PraisonAIAgents Affected by Environment Variable Secret Exfiltration via os.path.expandvars() Bypassing shell=False in Shell Tool

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the execute_command function in shell_tools.py calls os.path.expandvars() on every command argument at line 64, manually re-implementing shell-level environment variable expansion despite using shell=False (line 88) for security. This allows exfiltration of secrets stored in environment variables (database credentials, API keys, cloud access keys). The approval system displays the unexpanded $VAR references to human reviewers, creating a deceptive approval where the displayed command differs from what actually executes. This vulnerability is fixed in 1.5.128.

Severity ?

7.4 (High)

CVE-2026-40152 (GCVE-0-2026-40152)

Vulnerability from nvd – Published: 2026-04-09 21:26 – Updated: 2026-04-09 21:26

Title

PraisonAIAgents has a Path Traversal via Unvalidated Glob Pattern in list_files Bypasses Workspace Boundary

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, he list_files() tool in FileTools validates the directory parameter against workspace boundaries via _validate_path(), but passes the pattern parameter directly to Path.glob() without any validation. Since Python's Path.glob() supports .. path segments, an attacker can use relative path traversal in the glob pattern to enumerate arbitrary files outside the workspace, obtaining file metadata (existence, name, size, timestamps) for any path on the filesystem. This vulnerability is fixed in 1.5.128.

Severity ?

Vulnerability from nvd – Published: 2026-04-09 21:26 – Updated: 2026-04-09 21:26

Title

PraisonAIAgents has SSRF and Local File Read via Unvalidated URLs in web_crawl Tool

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the web_crawl() function in praisonaiagents/tools/web_crawl_tools.py accepts arbitrary URLs from AI agents with zero validation. No scheme allowlisting, hostname/IP blocklisting, or private network checks are applied before fetching. This allows an attacker (or prompt injection in crawled content) to force the agent to fetch cloud metadata endpoints, internal services, or local files via file:// URLs. This vulnerability is fixed in 1.5.128.

CVE-2026-40117 (GCVE-0-2026-40117)

Vulnerability from nvd – Published: 2026-04-09 21:21 – Updated: 2026-04-09 21:21

Title

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

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, read_skill_file() in skill_tools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skill_path parameter. Unlike file_tools.read_file which enforces workspace boundary confinement, and unlike run_skill_script which requires critical-level approval, read_skill_file has neither protection. An agent influenced by prompt injection can exfiltrate sensitive files without triggering any approval prompt. This vulnerability is fixed in 1.5.128.

CVE-2026-40111 (GCVE-0-2026-40111)

Vulnerability from nvd – Published: 2026-04-09 21:14 – Updated: 2026-04-09 21:14

Title

PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)

Summary

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 metacharacters are interpreted by /bin/sh before the intended command executes. Two independent attack surfaces exist. The first is via pre_run_command and post_run_command hook event types registered through the hooks configuration. The second and more severe surface is the .praisonai/hooks.json lifecycle configuration, where hooks registered for events such as BEFORE_TOOL and AFTER_TOOL fire automatically during agent operation. An agent that gains file-write access through prompt injection can overwrite .praisonai/hooks.json and have its payload execute silently at every subsequent lifecycle event without further user interaction. This vulnerability is fixed in 1.5.128.

Severity ?

CVE-2026-39888 (GCVE-0-2026-39888)

Vulnerability from nvd – Published: 2026-04-08 20:41 – Updated: 2026-04-09 20:21

Title

PraisonAIAgents has a sandbox escape via exception frame traversal in `execute_code` (subprocess mode)

Summary

PraisonAI is a multi-agent teams system. Prior to 1.5.115, execute_code() in praisonaiagents.tools.python_tools defaults to sandbox_mode="sandbox", which runs user code in a subprocess wrapped with a restricted __builtins__ dict and an AST-based blocklist. The AST blocklist embedded inside the subprocess wrapper (blocked_attrs of python_tools.py) contains only 11 attribute names — a strict subset of the 30+ names blocked in the direct-execution path. The four attributes that form a frame-traversal chain out of the sandbox are all absent from the subprocess list (__traceback__, tb_frame, f_back, and f_builtins). Chaining these attributes through a caught exception exposes the real Python builtins dict of the subprocess wrapper frame, from which exec can be retrieved and called under a non-blocked variable name — bypassing every remaining security layer. This vulnerability is fixed in 1.5.115.

Severity ?

CVE-2026-40153 (GCVE-0-2026-40153)

Vulnerability from cvelistv5 – Published: 2026-04-09 21:27 – Updated: 2026-04-09 21:27

Title

PraisonAIAgents Affected by Environment Variable Secret Exfiltration via os.path.expandvars() Bypassing shell=False in Shell Tool

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the execute_command function in shell_tools.py calls os.path.expandvars() on every command argument at line 64, manually re-implementing shell-level environment variable expansion despite using shell=False (line 88) for security. This allows exfiltration of secrets stored in environment variables (database credentials, API keys, cloud access keys). The approval system displays the unexpanded $VAR references to human reviewers, creating a deceptive approval where the displayed command differs from what actually executes. This vulnerability is fixed in 1.5.128.

Severity ?

7.4 (High)

Prior to 1.5.128, he list_files() tool in FileTools validates the directory parameter against workspace boundaries via _validate_path(), but passes the pattern parameter directly to Path.glob() without any validation. Since Python's Path.glob() supports .. path segments, an attacker can use relative path traversal in the glob pattern to enumerate arbitrary files outside the workspace, obtaining file metadata (existence, name, size, timestamps) for any path on the filesystem. This vulnerability is fixed in 1.5.128.

Severity ?

CVE-2026-40150 (GCVE-0-2026-40150)

Vulnerability from cvelistv5 – Published: 2026-04-09 21:26 – Updated: 2026-04-09 21:26

Title

PraisonAIAgents has SSRF and Local File Read via Unvalidated URLs in web_crawl Tool

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, the web_crawl() function in praisonaiagents/tools/web_crawl_tools.py accepts arbitrary URLs from AI agents with zero validation. No scheme allowlisting, hostname/IP blocklisting, or private network checks are applied before fetching. This allows an attacker (or prompt injection in crawled content) to force the agent to fetch cloud metadata endpoints, internal services, or local files via file:// URLs. This vulnerability is fixed in 1.5.128.

Severity ?

7.7 (High)

Vulnerability from cvelistv5 – Published: 2026-04-09 21:21 – Updated: 2026-04-09 21:21

Title

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

Summary

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, read_skill_file() in skill_tools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skill_path parameter. Unlike file_tools.read_file which enforces workspace boundary confinement, and unlike run_skill_script which requires critical-level approval, read_skill_file has neither protection. An agent influenced by prompt injection can exfiltrate sensitive files without triggering any approval prompt. This vulnerability is fixed in 1.5.128.

CVE-2026-40111 (GCVE-0-2026-40111)

Vulnerability from cvelistv5 – Published: 2026-04-09 21:14 – Updated: 2026-04-09 21:14

Title

PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)

Summary

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 metacharacters are interpreted by /bin/sh before the intended command executes. Two independent attack surfaces exist. The first is via pre_run_command and post_run_command hook event types registered through the hooks configuration. The second and more severe surface is the .praisonai/hooks.json lifecycle configuration, where hooks registered for events such as BEFORE_TOOL and AFTER_TOOL fire automatically during agent operation. An agent that gains file-write access through prompt injection can overwrite .praisonai/hooks.json and have its payload execute silently at every subsequent lifecycle event without further user interaction. This vulnerability is fixed in 1.5.128.

CVE-2026-39888 (GCVE-0-2026-39888)

Vulnerability from cvelistv5 – Published: 2026-04-08 20:41 – Updated: 2026-04-09 20:21

Title

PraisonAIAgents has a sandbox escape via exception frame traversal in `execute_code` (subprocess mode)

Summary

PraisonAI is a multi-agent teams system. Prior to 1.5.115, execute_code() in praisonaiagents.tools.python_tools defaults to sandbox_mode="sandbox", which runs user code in a subprocess wrapped with a restricted __builtins__ dict and an AST-based blocklist. The AST blocklist embedded inside the subprocess wrapper (blocked_attrs of python_tools.py) contains only 11 attribute names — a strict subset of the 30+ names blocked in the direct-execution path. The four attributes that form a frame-traversal chain out of the sandbox are all absent from the subprocess list (__traceback__, tb_frame, f_back, and f_builtins). Chaining these attributes through a caught exception exposes the real Python builtins dict of the subprocess wrapper frame, from which exec can be retrieved and called under a non-blocked variable name — bypassing every remaining security layer. This vulnerability is fixed in 1.5.115.

Severity ?
