Vulnerability from fkie_nvd - Published: 2025-03-20 19:15 - Updated: 2026-06-17 09:08
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Redlib is an alternative private front-end to Reddit. A vulnerability has been identified in Redlib where an attacker can cause a denial-of-service (DOS) condition by submitting a specially crafted base2048-encoded DEFLATE decompression bomb to the restore_preferences form. This leads to excessive memory consumption and potential system instability, which can be exploited to disrupt Redlib instances. This vulnerability is fixed in 0.36.0.
