CVE-2026-13723

Develar’s app-builder zipx.Unzip in macOS APFS is vulnerable to arbitrary file overwrite via Unicode normalization collision combined with unsafe symlink following. The root cause is lack of canonical normalization before path validation/writes, allowing a crafted ZIP with a symlink named ss (poi...

CVE-2026-13723 Develar's electron-builder allows arbitrary file overwrite

A vulnerability in the zipx.Unzip extraction routine of Develar's app-builder allows an attacker to overwrite arbitrary files on macOS APFS by exploiting a Unicode Normalization Collision combined with symlink following behavior. APFS treats certain Unicode equivalent filenames as identical e.g.,...

GHSA-7RQJ-J65F-68WH Auth.js: Email normalizer validates the address before Unicode normalization, allowing a homoglyph @ bypass

Summary The default email-address normalizer used by the email/magic-link sign-in flow validates the address before applying Unicode normalization. An address can contain a Unicode character that is not an ASCII @ U+0040 but canonicalizes to one under NFKC/NFKD normalization the normalization...
