What is CWE-1050?

This vulnerability occurs when a loop contains code that repeatedly consumes critical system resources like file handles, database connections, memory, or session locks. Each iteration of the loop drains these finite platform assets without proper release.
At its core, this is a resource management flaw within an iterative process. The loop body or its exit condition performs operations—such as opening files, creating network connections, or acquiring synchronization locks—that allocate platform-level resources. If these resources are not explicitly freed or closed within the same iteration, they accumulate with each pass. This quickly exhausts available pools, leading to severe performance degradation, application instability, or complete failure when the system runs out of descriptors, memory, or other critical assets. While this often manifests as a performance bug, it becomes a security vulnerability when an attacker can control the loop's iteration count. By forcing an excessive number of cycles—for example, by submitting specially crafted input—they can trigger sustained resource exhaustion. This creates a reliable denial-of-service (DoS) condition, rendering the application or even the host platform unresponsive as it starves other processes of necessary resources.

How attackers exploit it

Step-by-step attacker path

  1. 1

    Identify a code path that handles untrusted input without validation.

  2. 2

    Craft a payload that exercises the unsafe behavior — injection, traversal, overflow, or logic abuse.

  3. 3

    Deliver the payload through a normal request and observe the application's reaction.

  4. 4

    Iterate until the response leaks data, executes attacker code, or escalates privileges.

Vulnerable code example

Vulnerable pseudo

MITRE has not published a code example for this CWE. The pattern below is illustrative — see Resources for canonical references.

Vulnerable pseudo 
// Example pattern — see MITRE for the canonical references.
function handleRequest(input) {
  // Untrusted input flows directly into the sensitive sink.
  return executeUnsafe(input);
}
Secure code example

Secure pseudo

Secure pseudo 
// Validate, sanitize, or use a safe API before reaching the sink.
function handleRequest(input) {
  const safe = validateAndEscape(input);
  return executeWithGuards(safe);
}
What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
Prevention checklist

How to prevent CWE-1050

  • Architecture Use safe-by-default frameworks and APIs that prevent the unsafe pattern from being expressible.
  • Implementation Validate input at trust boundaries; use allowlists, not denylists.
  • Implementation Apply the principle of least privilege to credentials, file paths, and runtime permissions.
  • Testing Cover this weakness in CI: SAST rules + targeted unit tests for the data flow.
  • Operation Monitor logs for the runtime signals listed in the next section.
Detection signals

How to detect CWE-1050

SAST High

Run static analysis (SAST) on the codebase looking for the unsafe pattern in the data flow.

DAST Moderate

Run dynamic application security testing against the live endpoint.

Runtime Moderate

Watch runtime logs for unusual exception traces, malformed input, or authorization bypass attempts.

Code review Moderate

Code review: flag any new code that handles input from this surface without using the validated framework helpers.
