CVE-2026-13676

A flaw was found in fast-uri. This vulnerability occurs because fast-uri fails to properly convert Unicode Internationalized Domain Name - IDN hostnames for HTTP-family URLs. This can lead to a situation where security policies, such as denylists or redirect validations, are bypassed when...

gnutls: GnuTLS: Policy bypass due to case-sensitive nameConstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

CVE-2026-13676

fast-uri versions 2.3.1 through 3.1.2 and 4.0.0 fail to canonicalize Unicode IDN hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize and equal still return...

CVE-2026-13676

The CVE concerns the fast-uri library (versions 2.3.1–3.1.2 and 4.0.0) where the IDN host canonicalization path fails to normalize Unicode hosts for HTTP URLs. A helper used in IDN conversion does not exist on the global URL constructor, leaving the host in Unicode form while normalize() and equa...

CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo implementation subsys/net/lib/sockets/getaddrinfo.c passes a pointer to a stack-allocated state object struct getaddrinfostate aistate as the userdata of an asynchronous DNS resolver query. The socket layer waits on a semaphore with a timeout deliberately set...

CVE-2026-10646

Zephyr's BSD-sockets getaddrinfo() (subsys/net/lib/sockets/getaddrinfo.c) has a use-after-return risk from a stack-allocated ai_state being kept as user_data during a DNS resolver retry. If a semaphore wait times out and the code retries without cancelling the previous query or resetting the sema...

CVE-2026-10646 Use-after-return in `zsock_getaddrinfo()` when a timed-out DNS query is retried without cancellation

Zephyr's BSD-sockets getaddrinfo implementation subsys/net/lib/sockets/getaddrinfo.c passes a pointer to a stack-allocated state object struct getaddrinfostate aistate as the userdata of an asynchronous DNS resolver query. The socket layer waits on a semaphore with a timeout deliberately set...

SUSE CVE-2026-56123

socat versions 1.8.0.0 through 1.8.1.1 contain a heap-based buffer overflow vulnerability that allows a malicious SOCKS5 proxy server to overwrite adjacent heap memory by exploiting a sign-extension flaw in the DOMAINNAME reply parser. During connection setup, the domain name length byte is read...

EulerOS 2.0 SP15 : bind (EulerOS-SA-2026-2434)

According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : If a BIND resolver is performing DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU...

Statamic Vulnerable to Server-Side Request Forgery via Glide (DNS rebinding)

Impact The Glide image proxy's URL validation could be bypassed using DNS rebinding. The remote hostname was validated as publicly routable, but resolved again when the image was actually fetched, so an attacker controlling the hostname's DNS could rebind it to an internal address after validatio...
