CVE-2026-84894
Last modified
CVE-2026-84894 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In moxygen before commit 004123dd24c3, MoQSession::dataStreamReadLoop keeps using a stream read handle after reading a FIN, which invalidates the handle under proxygen's WebTransport API. A remote peer can trigger the stale use by opening a data stream that names an unknown track alias and carries the FIN in the same write.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
