Doc Text:	A flaw was found in node-re2, a library providing RE2 regular expression bindings for Node.js. A local attacker could exploit this vulnerability by providing a specially crafted input buffer that ends with an incomplete multi-byte UTF-8 character. This could lead to an out-of-bounds read, potentially disclosing sensitive information from adjacent memory locations.	Story Points:	---

Description OSIDB Bzimport 2026-08-06 22:26:08 UTC

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, incomplete code point. This could result in an out-of-bounds read and potential disclosure of adjacent memory contents. This issue is fixed in version 1.26.1.
