VulnerabilityCVE-2025-55181cvecve-2025-55181cwe-834
Published: Tue Dec 02 2025 (12/02/2025, 22:13:31 UTC)
Source: CVE Database V5
Vendor/Project: Facebook
Product: proxygen

Description

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 causes the process to run out of memory.
