CVE-2026-71430: Reachable Assertion

node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.25.1, the WrappedRE2::Replace function built its replacement result and passed it to V8 using ToLocalChecked without checking for the empty MaybeLocal that V8 returns when the resulting string or buffer exceeds V8's...

CVE-2026-71498: Out-of-bounds Read

node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated incomplete multi-byte UTF-8 sequence could cause the native binding to read past the end of the allocated buffer while attempting to decode the final,...

PT-2026-68815

Name of the Vulnerable Software and Affected Versions node-re2 versions prior to 1.26.1 Description An out-of-bounds read exists when passing a Buffer whose final bytes form a truncated multi-byte UTF-8 sequence. The native binding fails to validate the remaining buffer size when decoding the fin...

CVE-2026-67550

A flaw was found in re2, a component that provides Node.js bindings for Google's RE2 regular expression engine. An attacker can exploit a vulnerability by manipulating the lastIndex parameter with a non-ASCII input. This manipulation can lead to an out-of-bounds heap read, causing the process to...

GHSA-FF84-5F28-78QJ re2: Out-of-bounds heap read in `exec`/`test`/`match` via attacker-influenced `lastIndex` on a non-ASCII subject → uncatchable process crash (DoS)

Summary re2 validates the user-settable lastIndex against the subject's UTF-8 byte length but then uses it as a UTF-16 code-unit count to walk the subject buffer, with no bounds check. For any non-ASCII subject, the byte length is larger than the true character count, so a lastIndex between those...

re2: Global `String.prototype.match` with an empty-matchable pattern never advances → infinite loop with unbounded native memory growth (DoS)

Summary String.prototype.match with a global RE2 collects all matches in a native loop that advances the cursor by the match length. A zero-width empty match has length 0, so the cursor never advances: the same empty match is found forever and appended to an ever-growing native vector. Any patter...
