CVE-2026-59941

CVE-2026-59941 (Dompdf) affects Dompdf (PHP HTML-to-PDF converter) up through version 3.15. The root cause is that a BMP image’s declared width/height in the header is trusted, leading to allocation of a full GD canvas (e.g., 6000×6000) even if pixel data is minimal. This enables a lightweight 16...

CVE-2026-64646

CVE-2026-64646 affects Next.js versions 13.0.0–15.5.20 and 16.0.0–16.2.10 where App Router Server Actions running in the Edge runtime can cause unbounded memory growth from oversized Server Action payloads. Impact is excessive memory consumption; fix is upgrade to Next.js 15.5.21 or 16.2.11 (or l...

CVE-2026-64646 Next.js: Unbounded Server Action payload in Edge runtime

Next.js is a React framework for building full-stack web applications. In versions 13.0.0 through 15.5.20 and 16.0.0 through 16.2.10, requests targeting Next.js applications using App Router with at least one Server Action can lead to excessive memory consumption if that Server Actions uses the...

dovecot: Dovecot: Denial of Service via excessive IMAP bracing

A flaw was found in Dovecot. A remote attacker can exploit this vulnerability by sending excessive open braces over the Internet Message Access Protocol IMAP, leading to uncontrolled memory usage. This can cause the affected system to consume memory up to its configured limit, resulting in a Deni...

SUSE CVE-2026-11622

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

Denial Of Service (DoS)

pypdf is vulnerable to Denial Of Service DoS. The vulnerability is due to improper validation of declared image size values during PDF image parsing, which allows an attacker to craft a malicious PDF that triggers excessive memory consumption and causes a denial-of-service condition...
