| CVE-2025-5222 | A stack buffer overflow was found in Internationl components for unicode (ICU ). While running the genrb binary, the 'subtag' struct overflowed at the SRBRoot::addTag function. This issue may lead to memory corruption and local arbitrary code execution. | [email protected] | 7.0 | 0.30% | 2025-05-27 | 2026-06-17 |
| CVE-2021-42694 | An issue was discovered in the character definitions of the Unicode Specification through 14.0. The specification allows an adversary to produce source code identifiers such as function names using homoglyphs that render visually identical to a target identifier. Adversaries can leverage this to inject code via adversarial identifier definitions in upstream software dependencies invoked deceptively in downstream software.

| CVE-2021-42574 | An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers.

| CVE-2020-21913 | International Components for Unicode (ICU-20850) v66.1 was discovered to contain a use after free bug in the pkg_createWithAssemblyCode function in the file tools/pkgdata/pkgdata.cpp. | [email protected] | 5.5 | 1.13% | 2021-09-20 | 2026-06-17 |
| CVE-2016-10610 | unicode-json is a unicode lookup table. unicode-json before 2.0.0 downloads data resources over HTTP, which leaves it vulnerable to MITM attacks. | [email protected] | 8.1 | 0.55% | 2018-06-01 | 2026-06-17 |
