    CVE-2026-13723 (GCVE-0-2026-13723)

    Vulnerability from nvd – Published: 2026-07-29 17:25 – Updated: 2026-07-29 18:21
    VLAI
    Title
    Develar's electron-builder allows arbitrary file overwrite
    Summary
    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., ß ↔ ss), while app builder performs no canonical normalization before validating or writing paths. As a result, a crafted ZIP archive containing: • a symlink entry named ss pointing to a target file, and • a regular file named ß containing attacker controlled data, will cause the second write to follow the symlink and overwrite the target file.
