CVE-2025-22871 (GCVE-0-2025-22871)
Vulnerability from cvelistv5 – Published: 2025-04-08 20:04 – Updated: 2025-04-18 14:57
VLAI?
Summary
The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.
Severity ?

CVE-2023-39326 (GCVE-0-2023-39326)
Vulnerability from cvelistv5 – Published: 2023-12-06 16:27 – Updated: 2025-02-13 17:02
VLAI?
Summary
A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small.
Severity ?
No CVSS data available.
