Service interruption via unbounded preference decompression
Published Mar 20, 2025 · Updated Mar 20, 2025
Uncontrolled resource consumption in Redlib before 0.36.0 allows remote attackers to crash an instance via encoded preference restoration. The unauthenticated encoded_restore handler base2048-decodes an encoded_prefs form value and DEFLATE-decompresses it without input, time, or output limits. Network access to the public restoration route is sufficient; a decompression bomb exhausts memory, degrading or crashing the service without reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
