crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

github.com/go-jose/go-jose/v3: github.com/go-jose/go-jose/v4: Go JOSE: Denial of Service via crafted JSON Web Encryption (JWE) object

A flaw was found in Go JOSE, a library for handling JSON Web Encryption JWE objects. A remote attacker could exploit this vulnerability by providing a specially crafted JWE object. When decrypting such an object, if a key wrapping algorithm is specified but the encrypted key field is empty, the...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

CVE-2026-5090

The CVE concerns Template::Plugin::HTML for Perl, affecting versions up to and including 3.102. The root cause is that html_filter fails to escape single quotes, allowing HTML attributes delimited by single quotes to be injected with limited HTML/JavaScript. For example, in , a value like var = "...

Dasel: Denial of service in dasel selector lexer due to infinite loop on unterminated regex literal

Summary dasel's selector lexer enters a non-terminating loop when tokenizing an unterminated regex pattern such as r/abc. A 2-byte input r/ is sufficient to cause the tokenizer to consume 100% CPU on one core indefinitely. I confirmed the issue on v3.3.1 fba653c7f248aff10f2b89fca93929b64707dfc8 a...

USN-8276-1: Highlight.js vulnerability

It was discovered that Highlight.js used plain JavaScript objects for internal language name lookups, making them susceptible to prototype pollution attacks. An attacker could use this to cause a denial of service or unexpected application behaviour...
