The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

libuv is a multi-platform support library with a focus on asynchronous I/O. The uv_getaddrinfo
function in src/unix/getaddrinfo.c
(and its windows counterpart src/win/getaddrinfo.c
), truncates hostnames to 256 characters before calling getaddrinfo
. This behavior can be exploited to create addresses like 0x00007f000001
, which are considered valid by getaddrinfo
and could allow an attacker to craft payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due to how the hostname_ascii
variable (with a length of 256 bytes) is handled in uv_getaddrinfo
and subsequently in uv__idna_toascii
. When the hostname exceeds 256 characters, it gets truncated without a terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar to MySpace) that allows users to have username.example.com
pages. Internal services that crawl or cache these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username. This issue has been addressed in release version 1.48.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
