Excessive read buffering DoS in http.client
CVE-2025-13836 is fixed in 142 products on 2 platforms, first by idle-python3.10 3.10.12-1~22.04.13, released December 1, 2025. 9 other affected products have no fix yet. It is not reported as exploited. Patch Radar priority: High.
When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS.
