Short explanation
CVE-2026-118773 is an AbortSignal cancellation bypass vulnerability in isaacs node-glob from version 9.0.0 until 14.0.2. Execution continuing after cancellation signals can lead to unintended filesystem traversal and resource consumption [S0].
This vulnerability can stack background filesystem operations and CPU work through repeated timed-out requests, degrading worker throughput or service availability [S0].
What should be done?
- Follow the vendor advisory to apply appropriate guidance [S0].
- Review exposure regarding attacker-influenced patterns and directory trees [S0].
Chain of evidence and sources
9.0.0 ile 14.0.2 sürümleri arasındaki node-glob bileşeninde AbortSignal iptal atlatması görülebilir [S0].
Zafiyet, gizlilik veya bütünlük üzerinde etki yaratmazken hizmet erişilebilirliğini düşürebilir [S0].
Show the technical text from the sources
Glob matches files using patterns the shell uses. From 9.0.0 until 14.0.2, abort branches in src/walker.ts, including GlobUtil.walkCB(), GlobUtil.walkCB2(), GlobUtil.walkCBSync(), and GlobUtil.walkCB2Sync(), invoke the callbacks without returning. After AbortSignal or AbortSignal.timeout() rejects or emits an error, execution can continue into processor.processPatterns(), readdirCB(), and recursive traversal. The issue affects glob() and globStream() when applications expose attacker-influenced patterns or directory trees and rely on cancellation as a traversal budget. Repeated timed-out requests can stack background filesystem operations and CPU work, degrading worker throughput or service availability; no confidentiality or integrity impact was observed. This issue is fixed in 14.0.2.
