ecosystem impact- 298,825 npm packages depend on braces (5,739 direct, 293,215 indirect)
Ecosystem-wide dependent count for version 3.0.3.
DescriptionCVE.org
The NPM package braces, versions prior to 3.0.3, fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In lib/parse.js, if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.
AnalysisAI
The NPM package braces, versions prior to 3.0.3, fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
Technical ContextAI
This vulnerability is classified under CWE-1050. The NPM package braces, versions prior to 3.0.3, fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In lib/parse.js, if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash. Affected products include: Jonschlinkert Braces. Version information: prior to 3.0.3.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Apply vendor patches when available. Implement network segmentation and monitoring as interim mitigations.
