CVE-2023-22898Network attack vector

Service interruption via unbounded recursive ZIP extraction

Published Jan 10, 2023 · Updated Apr 7, 2025

Denial of service in Pandora 1.3.0 allows remote attackers to interrupt file analysis by submitting a deeply nested ZIP archive. The extractor recursively creates tasks for archive contents without enforcing depth or aggregate extracted-file limits. A user must cause the submitted archive to be analyzed; resource exhaustion can stall analysis but does not expose or alter data.
