minimatch: Minimatch: Denial of Service via catastrophic backtracking in glob expressions

A flaw was found in minimatch. A remote attacker could exploit this vulnerability by providing a specially crafted glob expression with nested unbounded quantifiers. This could lead to catastrophic backtracking in the V8 JavaScript engine, causing the application to become unresponsive and...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS when including multiple regular expression parameters in a single segment, separated by something that is not a period .. Poor performance will block the event loop and can lead to a DoS. Note:...

CVE-2026-4867

Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period .. For example, /:a-:b-:c or /:a-:b-:c-:d. The backtrack protection added in [email protected] only prevents ambiguity for two...
