Routine
MEDIUM 6.2
CVE-2026-68499 is a medium-severity flaw (CVSS 6.2) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
