CVE-2026-84895
In proxygen from v2026.04.06.00 until v2026.09.28.00, QuicWtSession::closeSession accesses its member fields after calling the base QuicWtSessionBase::closeSession method. The base method notifies the session handler, which may release the last reference to the session and destroy it...
CVE-2026-84895
The proxygen software (versions 2026.04.06.00 through 2026.09.28.00 ) is vulnerable to a use-after-free condition in the QuicWtSession::closeSession function. The flaw occurs because the function accesses member fields after invoking the base QuicWtSessionBase::closeSession method, which may noti...
CVE-2026-91096: Use After Free
In proxygen from v2024.10.28.00 until v2026.09.28.00, WebTransportImpl::terminateSessionStreams WebTransportImpl::destroy in releases before v2025.08.18.00 failed to unregister read callbacks for streams that were no longer open before destroying them. The transport could then invoke a read...

CVE-2026-91095: Use After Free
In proxygen from v2024.10.28.00 until v2026.09.28.00, the HTTPTransaction::onWebTransportUniStream and HTTPTransaction::onWebTransportBidiStream APIs could return stream handles that the stream handler had already freed. HQSession then installed those handles as transport read callbacks, which...
CVE-2026-44909
A flaw was found in Proxygen. A remote, unauthenticated attacker could exploit a missing slow-consumer detection mechanism in the HTTP/2 protocol. By manipulating HTTP/2 flow-control settings, an attacker can force the server to buffer large amounts of data in memory indefinitely. This can lead t...
CVE-2026-44909
Proxygen lacked a generalized slow-consumer detection mechanism in its core HTTP session layer. A remote, unauthenticated attacker could exploit HTTP/2 flow-control by setting SETTINGSINITIALWINDOWSIZE to 0 or withholding WINDOWUPDATE frames, causing the server to buffer complete response bodies ...

CVE-2019-11921
An out of bounds write is possible via a specially crafted packet in certain configurations of Proxygen due to improper handling of Base64 when parsing malformed binary content in Structured HTTP Headers. This issue affects versions of proxygen prior to v2019.07.22.00...
CVE-2025-55181
A flaw was found in proxygen. This vulnerability allows a denial of service DoS via sending an HTTP Hypertext Transfer Protocol request/response body with greater than 2^31 bytes, triggering an infinite loop and unbounded memory growth...
CVE-2025-55181
Sending an HTTP request/response body with greater than 2^31 bytes triggers an infinite loop in proxygen::coro::HTTPQuicCoroSession which blocks the backing event loop and unconditionally appends data to a std::vector per-loop iteration. This issue leads to unbounded memory growth and eventually...
