CVE-2026-3590

Mattermost versions 10.11.x = 10.11.12, 11.5.x = 11.5.0, 11.4.x = 11.4.2, 11.3.x = 11.3.2 fail to enforce atomic single-use consumption of guest magic link tokens, which allows an attacker with access to a valid magic link to establish multiple independent authenticated sessions via concurrent...

JLSEC-2026-90

Poppler is a PDF rendering library. Versions prior to 25.06.0 use std::atomicint for reference counting. Because std::atomicint is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue...

ClickFix finds a new way to infect Macs

ClickFix campaigns are looking for alternatives now that many Mac users have been made aware of the dangers of pasting certain commands into Terminal. Researchers found that ClickFix has kept the same social engineering playbook but completely sidestepped Terminal by using the applescript:// URL...

CVE-2026-32602

Homarr is an open-source dashboard. Prior to 1.57.0, the user registration endpoint /api/trpc/user.register is vulnerable to a race condition that allows an attacker to create multiple user accounts from a single-use invite token. The registration flow performs three sequential database operation...

CVE-2026-23399

CVE-2026-23399 concerns the Linux kernel nf_tables code: when cloning the second stateful expression in a dynset element, the first expression could remain unfreed on error, causing a stateful memleak in error paths. The provided CVE description confirms a resolution in the kernel, with backtrace...

CVE-2026-32943

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.28 and 8.6.48, the password reset mechanism does not enforce single-use guarantees for reset tokens. When a user requests a password reset, the generated token can be...

CVE-2026-23316

A flaw was found in the Linux kernel's handling of multipath hash seeds on ARM64 architectures. This vulnerability can lead to a system crash kernel panic when the kernel is compiled with specific optimizations, such as Clang with Link-Time Optimization LTO, due to an alignment fault during memor...

CVE-2026-23383

CVE-2026-23383 affects the Linux kernel’s BPF JIT path on arm64. The root cause was 4-byte alignment in bpf_jit_binary_pack_alloc() causing the JIT buffer’s base to be only 4-byte aligned, which could misalign the 64-bit target field in struct bpf_plt. Consequences include UBSAN misaligned-access...
