"value": "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:\r\n•\ta symlink entry named ss pointing to a target file, and\r\n•\ta regular file named ß containing attacker controlled data,\r\nwill cause the second write to follow the symlink and overwrite the target file."
