Some libraries (like Zip4j ) fail to verify the Message Authentication Code (MAC) during decryption, potentially allowing for information disclosure or file modification. Mitigation Strategies
Applications must sanitize file paths to prevent directory traversal attacks. l0g.zip
A file like l0g.zip may be a non-recursive zip bomb . Unlike older recursive bombs that nested archives within archives, modern versions use overlapping files inside the container to achieve massive compression ratios (e.g., 46MB expanding to 4.5PB) without nesting.
