0 Apache bRPC versions prior to 1.18.0 contain a vulnerability where unbounded memory accumulation occurs in the stream message reassembly process. Remote attackers can exploit this by sending an endless sequence of continuation data frames, causing the server to exhaust memory and potentially crash or become unavailable. The issue arises because fragmented stream messages accumulate continuation frames without limits, and default flow-control settings do not throttle the sending rate. The vulnerability affects services accepting streams from untrusted clients using the built-in streaming protocol. The issue is fixed in version 1.18.0 by limiting the accumulated payload to max_body_size (default 64MB), closing streams that exceed this limit with an error. Adjusting max_body_size is possible to accommodate legitimate large messages. Join the discussion | CVE Database V5 | 10/21/2026, 11:57:30 UTC Added: 10/21/2026, 12:04:02 UTC |
