SUSE CVE-2026-42554
Fiber is a web framework for Go. Prior to 2.52.12 and 3.1.0, Cross-Site Scripting vulnerability in Go Fiber allows a remote attacker to inject arbitrary HTML/JavaScript by supplying Accept: text/html on any request whose handler passes attacker-influenced data to the AutoFormat feature. The...
CVE-2026-66062
SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.70.2, the content negotiation header parser used by SvelteKit's request handling for headers such as Accept uses a regular expression vulnerable to quadratic backtracking, so a maliciously...
GHSA-29G2-3RMR-QM68 SvelteKit: ReDoS (O(n^2)) in content negotiation — unauthenticated DoS via the Accept header
Impact SvelteKit is vulnerable to remote CPU-exhaustion DoS attacks via specifically-crafted Accept headers. The impact is mitigated by default header length limits on most platforms, but in the case of raised or absent limits a denial of service is possible. Patches The vulnerability is patched ...

CVE-2026-66062
SvelteKit before 2.70.2 uses a content-negotiation header parser that employs a regular expression vulnerable to quadratic backtracking. A crafted Accept header can cause excessive CPU use, leading to degraded performance or denial of service. The issue is fixed in 2.70.2. No exploitation details...
