Doc Text:
A flaw was found in the mime/multipart and net/textproto packages in Go. A remote attacker could exploit this vulnerability by submitting a crafted multipart form request that bypasses configured memory limits when the remaining boundary limit is small. This issue allows the application to read an arbitrarily long line into memory, leading to excessive resource consumption and a Denial of Service (DoS).

Description OSIDB Bzimport 2026-10-08 23:01:40 UTC
Parsing a multipart form can bypass memory limits and read an arbitrarily long line into memory when the remaining limit at the start of a part is less than 400 bytes.
