EUVD-2026-39972

7-Zip for Windows through 26.02 fails to preserve the Mark-of-the-Web when extracting a crafted RAR5 archive, because its guard that suppresses an archive-supplied Zone.Identifier stream matches the exact name 'Zone.Identifier' while a RAR5 STM record named ':Zone.Identifier:$DATA' is not matched...

CVE-2026-52690

CVE-2026-52690 affects the PowerDNS Recursor. Spoofed replies can cause an authoritative server’s IP to be marked as not supporting EDNS, leading to DNSSEC validation failures for records served by that server. The vulnerability’s impact is documented as enabling validation failures in the presen...

CVE-2026-52690 Spoofed answers can mark an authoritative non-EDNS capable

Spoofing replies to Recursor might mark an IP of an authoritative server as not supporting EDNS, causing valdiation of DNSSEC records served by that server to fail...

CVE-2026-48772

ProxySQL is a proxy for MySQL and its forks, as well as PostgreSQL. In versions 2.0.0 through 3.0.8, the ProxySQL MySQL frontend accepts the PROXY UNKNOWN \r\n PP1 frame as a well-formed PROXY protocol header. The HAProxy PROXY protocol v1 specification says that when the protocol token is UNKNOW...

CVE-2026-48772

ProxySQL (versions 2.0.0–3.0.8) is vulnerable to a PROXY protocol v1 UNKNOWN frame bypass. The frontend accepts the PROXY UNKNOWN header and, despite the spec requiring ignoring the address fields, ProxySQL parses them via sscanf and writes a spoofed source address into the session, feeding i...

CVE-2026-49231

Authentication Bypass by Spoofing vulnerability in opa plugin. An attacker could relay spoofed identity headers to upstream capitalising on non-default configuration in opa plugin. This could allow the attacker to assume higher privileges on the upstream service. This issue affects Apache APISIX:...

CVE-2026-44046

Use of Less Trusted Source vulnerability in Apache APISIX. Attacker can take advantage of wolf-rbac plugin under default configuration to potentially pollute logs with spoofed identity information and exploit IP based access control rules. This issue affects Apache APISIX: from 1.2.0 through...

Astra Linux – Vulnerability in exim4

Before version 4.97.1, Exim allowed SMTP smuggling in certain pipeline/chunking configurations. Remote attackers could use a known exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, thereby bypassing an SPF protection mechanism. This issue arises because Exim...

Astra Linux – Vulnerability in NTP

In NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, ntpd allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address. This occurs because transmissions are rescheduled even when a packet lacks a valid origin timestamp...

Astra Linux – Vulnerability in NTP

In NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, remote attackers could exploit this vulnerability to cause a denial of service—resulting in the daemon exiting or the system time being changed. This was possible by predicting the transmit timestamps used in forged packets. The victim w...

Name of the Vulnerable Software and Affected Versions Apache APISIX versions 3.5.0 through 3.16.0 Description An authentication bypass issue exists in the opa plugin. An attacker can relay spoofed identity headers to upstream services by exploiting non-default configurations in the opa plugin,...

CVE-2026-50194

Steeltoe CVE-2026-50194 affects management endpoints when configured to listen on an alternate port. Versions 3.2.2–3.3.0 and 4.1.0 use the Host header to gate access instead of the socket port, enabling port-isolation bypass. Patches are in 3.4.0 and 4.2.0. If upgrading isn’t possible, apply exp...

Missing Authentication for Critical Function vulnerability in RTI Connext Professional Security Plugins allows Fake the Source of Data.This issue affects Connext Professional: from 7.4.0 before 7.7.0, from 7.0.0 before 7.3.1.3, from 6.1.0 before 6.1., from 6.0.0 before 6.0., from 5.3.0 before 5.3...

Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to exposure of QUIC stateless reset tokens through connection ID generation, which allows an on-path attacker to derive the token and send spoofed Stateless Reset packets to terminate active connections...

CVE-2026-44894

A flaw was found in Netty, specifically within the netty-codec-classes-quic component's NoQuicTokenHandler. A remote attacker can exploit this vulnerability by sending an Initial packet with any non-empty token bytes and a spoofed victim's IP address. This improper token validation causes the Net...

Over 400 Arch Linux AUR Packages Hijacked to Deploy Infostealer and eBPF Rootkit

Attackers took over more than 400 packages in the Arch User Repository AUR this week and rewrote their build scripts to install a credential stealer on any machine that built them. The malware is a Rust binary built to harvest developer secrets. When it lands with root, it can also load an eBPF...

CVE-2026-44894

Netty is a network application framework for development of protocol servers and clients. NoQuicTokenHandler is the tokenHandler used when the application does not set one. Prior to version 4.2.15.Final, its writeToken returns false server will not send Retry — acceptable, but validateToken...
