Thirteen agent repos with disclosed vulnerabilities
Real vulnerabilities in real projects, not a synthetic benchmark. MCP servers, agent
frameworks, and one skill file. Every case shows the code as written and the fix, with the
original disclosure linked and the finder credited. None of it is our own discovery unless
the credit says so. Every code block marked with a commit was read straight out of that
repository at that commit. For what the scanner reports today, see
what Glance finds by category.
describe_table interpolates the caller's table_name straight into a PRAGMA. A name like `mytable); DROP TABLE users; --` runs as a second statement, so a tool that only reads schema can delete data.

elif name == "describe_table":
if not arguments or "table_name" not in arguments:
raise ValueError("Missing table_name argument")
table = arguments["table_name"]

raise ValueError("Not a table name")
results = db._execute_query(
"SELECT * FROM pragma_table_info(?)", (table,)
)
Fix Validate the table name against an identifier pattern, then bind it as a parameter to pragma_table_info() instead of formatting it into SQL.

src/db/utils.ts:20-24at a9eb08e
CriticalMCPNodeFixed upstreamSelf-assigned grade
The schema is chosen by running a regex over the raw SQL. MySQL treats a comment as whitespace, so USE/**/other_db never matches, the permission check is applied to the wrong schema, and the statement still executes.
The source issue was closed (completed) when this was checked on 2026-09-06.

// Case 1: USE database statement
const useMatch = sql.match(/USE\s+`?([a-zA-Z0-9_]+)`?/i);
if (useMatch && useMatch[1]) {
return useMatch[1];
}
suggested fix, not the upstream patch
// Parse, do not pattern-match. MySQL treats a comment as whitespace, so
// USE/**/other_db slips past a regex and the permission check then runs
// against the wrong schema.
const ast = parser.astify(sql, { database: "mysql" });
const statements = Array.isArray(ast) ? ast : [ast];
const used = statements.find((s) => s.type === "use");
if (used) {
return used.db;
}
Fix Parse the statement into an AST and read the USE target from it. A regex over SQL text can always be split by a comment.

HighMCPTypeScriptFixed upstream
A malicious page can inject a non-http URL that triggers Android Intent actions — opening attacker-controlled apps or reading local device files via file:///.
exec() in the host process gives LLM-generated code full access to the filesystem, env vars, and network — prompt injection turns this into instant RCE.

# Option A: Restrict to subprocess with timeout

capture_output=True, text=True,
timeout=5, # kill runaway code
user="nobody" # drop privileges
)
return result.stdout[:4096] # cap output size
# Option B: Use RestrictedPython or a container sandbox
Fix Run in subprocess with timeout and dropped privileges, or use a container sandbox (e2b, modal). Never exec() in the host process.
Memory hooks execute with shell=True — a poisoned memory entry (written by the LLM) can inject shell commands that run as the agent process. CVE-2026-40111.
src/praisonai-agents/praisonaiagents/memory/hooks.py:302-310 at 84c4d22
Two bugs together: shell injection via agent-controlled args, plus every environment variable (API keys, tokens, secrets) forwarded to every subprocess.

shell=True,

capture_output=True,
text=True,
timeout=60
)
Fix shell=False with shlex.split, plus a minimal explicit env. The docstring already promises constraints the code never enforced.

executor.go:100-105at fcbb32b
HighMCPGoSelf-assigned grade
validateCommand at security.go:23 matches patterns against the raw string, and that same string is then handed to bash -c. Command substitution rebuilds a blocked word out of fragments, so the check passes and the command still runs.
The source issue was closed (completed) when this was checked on 2026-09-06.
Fix Parse with shlex, allowlist the base binary, and exec the argument vector directly. Dropping bash -c is what removes the bypass, not a longer blocklist.
Anything written into agent memory — including content from web pages or tool responses — gets promoted to system prompt trust on the next turn. One malicious page poisons all future reasoning.

# user tier, not system tier
self._messages.append({"role": "user", "content": formatted})
Fix Cap and strip each memory before it is joined, and append it as a user message rather than editing the system message. Memory is something the agent read, not something the operator wrote.

The page title is whatever the page says it is. It is read at _multimodal_web_surfer.py:885 and interpolated into the QA prompt, so a page titled 'Ignore previous instructions' arrives as part of the operator's own text.

The example interpolates caller-supplied product_website and product_details straight into the task description. Developers copy these crews into their own projects, so one crafted input rewrites the task and every agent step after it.

HighSkillMarkdownAnti-patternSelf-assigned grade
Credentials hardcoded in a skill file are sent to the LLM API in every agent context window — and committed to version control history. Two separate exfiltration surfaces.
The credentials in this sample are redacted here. The point is the shape of the mistake, not the strings: a skill file is loaded verbatim into agent context, so anything written in one travels to every API call.

## Database Connection
Connect to the production database:
```python
import psycopg2
conn = psycopg2.connect(
host="[redacted]",
database="customers",
user="app_user",
password="[redacted]" # production password
)
```
API key for analytics: sk-ant-api03-[redacted]
suggested fix, not the upstream patch
## Database Connection
Connect using environment variables — never hardcode credentials:
```python
import psycopg2, os
conn = psycopg2.connect(
host=os.environ["DB_HOST"],
database=os.environ["DB_NAME"],
user=os.environ["DB_USER"],
password=os.environ["DB_PASS"]
)
```
Set credentials in your environment or secrets manager.
See: docs/secrets-setup.md
Fix Use environment variables. Rotate any exposed credentials immediately. Run detect-secrets in CI to catch this before commit.

src/tools/command-executor.ts:28-40at 4cfe462
LabLabTypeScriptBenchmark lab
A public MCP security benchmark, deliberately vulnerable, used here to show a scan of code nobody wrote for us. The tool takes a command string from the caller and hands it to execSync with the full process environment attached, so a single shell metacharacter turns a tool call into arbitrary code execution with whatever secrets that process holds.
src/tools/command-executor.ts:28-40 at 4cfe462
export async function handleExecuteCommand(args: any) {
const { command } = args;
try {
// VULNERABILITY: Direct command execution without sanitization!
// Should use parameterized commands or allowlist of safe commands
// Should NEVER concatenate user input into shell commands
// WRONG: Directly executing user-provided command
const output = execSync(command, {
encoding: 'utf-8',
// VULNERABILITY: No timeout
timeout: 60000, // Way too long!
Fix Never pass a caller-supplied string to a shell. Map named actions to fixed argument vectors, use execFile rather than exec, cut the timeout, and pass a minimal environment instead of process.env.
