| Property | Value |
|---|---|
| Advisory ID | SGZ-2026-1B3C5 |
| Severity | LOW |
| CWE | CWE-400 |
| Confidence | 78% |
| Category | memory_bug |
| Exploitability | possible |
| Package | fspoll@latest (golang) |
| Location | fspoll/poller.go:22-24 |
| Attack Vector | NETWORK |
| Attack Complexity | LOW |
| Privileges Required | NONE |
| Discovered By | SafeGuard Zero-Day AI Discovery Engine |
The Poller creates its events and errors channels with a buffer size of 1. Under high-frequency file change scenarios, the buffer can fill, causing the polling goroutine to block when sending events, which may lead to a denial‑of‑service condition.
The vulnerability was identified in the file fspoll/poller.go at lines 22-24 within the fspoll package (version latest). Any code path that invokes these functions inherits this vulnerability.
File: fspoll/poller.go (lines 22-24)
events: make(chan Event, 1),\nerrors: make(chan error, 1),
The code above demonstrates the vulnerable pattern. This code is executed at runtime and can be directly exploited by an attacker with the appropriate access level.
Trigger rapid file modifications on a watched path (e.g., via a loop that touches the file thousands of times). The events channel fills, causing the polling goroutine to block on send, halting further processing.
Denial of service by stalling the file watcher, potentially affecting dependent services.
Increase the channel buffer size or implement non‑blocking send with select and a fallback (e.g., drop events or queue them). Consider using a buffered channel sized based on expected event rate or a dedicated worker pool.
Advisory: SGZ-2026-1B3C5 | Source: SafeGuard Zero-Day AI Discovery | Status: Candidate
This vulnerability was autonomously discovered by SafeGuard's AI-powered Zero-Day Discovery engine using TAOR (Think-Act-Observe-Repeat) agentic analysis on the package source code. It is not yet tracked in any public vulnerability database (CVE, NVD, GHSA, OSV). This finding should be triaged by a security engineer and, if confirmed, reported upstream to the package maintainer.
