JavaScript vulnerability analysis and mitigation
Overview
Validate.js, a JavaScript library providing declarative object validation, contains a vulnerability identified as CVE-2020-26308 in versions 0.13.1 and prior. The vulnerability was discovered and reported by GitHub team member Erik Krogh Kristensen on November 30, 2020 (GitHub Issue).
Technical details
The vulnerability is classified as a Regular Expression Denial of Service (ReDoS) issue. The regular expression used to validate emails in the library contains patterns that are vulnerable to exponential backtracking, which can cause extremely poor performance given specifically crafted input strings (GitHub SecLab).
Impact
This vulnerability may lead to a denial of service condition when processing maliciously crafted input. When the affected regular expression processes certain specially constructed strings, it can cause the application to consume excessive CPU resources, potentially making the service unresponsive (GitHub SecLab).
Mitigation and workarounds
As of the time of publication, no known patches were available for this vulnerability (CVE Mitre).
