This medium-severity CVE scores 6.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (7th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
