Hi,

The following vulnerabilities were published for node-re2.

CVE-2026-68499[0]:
| 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.


CVE-2026-67550[1]:
| re2 provides Node.js bindings for Google's RE2 regular expression
| engine. Prior to 1.25.2, re2 validates lastIndex against the UTF-8
| byte length of a subject but uses it as a UTF-16 code-unit offset in
| exec, test, match, replace, and split, allowing an attacker-
| influenced lastIndex on a non-ASCII subject to trigger an out-of-
| bounds heap read and an uncatchable process crash, with limited heap
| information disclosure in some cases. This issue is fixed in 1.25.2.
