CVE-2026-68499: Uhop Node-RE2

Medium severity, CVSS 6.2. EPSS: 0.2% chance of exploitation in the next 30 days.

re2 provides Node.js bindings for Google's RE2 regular expression engine. Prior to 1.25.2, re2's String.prototype.match implementation with a global RE2 pattern that can match the empty string fails to advance its native matching cursor in lib/match.cc, causing an infinite loop and unbounded native memory growth that blocks the event loop and can exhaust host memory. This issue is fixed in 1.25.2.

Affected products

• Uhop Node-RE2: before 1.25.2 (fixed in 1.25.2)
