By sending an indefinite sequence of bytes with values `0x80` or above, a server or client can make the other peer parse these bytes into an ever-growing integer. Since Ruby integers are arbitrary precision, this can be used to make a WebSocket connection consume an unbounded amount of memory and lead to the host process running out of memory.\n\n### Patches\n\nThe issue has been patched in version 0.8.1. All users should upgrade to this version.\n\n### Workarounds\n\nNo known workarounds exist.\n\n### Acknowledgements\n\nThis issue was discovered and reported by Pranjali Thakur, DepthFirst Security Research Team.","public_affected_ranges":["< 0.8.1"]}],"null_published_at":"2026-11-03T10:03:26.542Z","source_updated_at":"2026-08-17T16:15:05.000Z","source_disclosed_at":"2026-07-15T22:01:52.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-02T20:15:44.568Z"}],"next_cursor":null,"snapshot_revision":"42594"}
