• 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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

| Description | 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. | |
