CVE-2026-42534 MEDIUM PATCH This Month

Resolution performance degradation in NLnet Labs Unbound 1.25.0 and earlier allows an unauthenticated remote attacker - who also controls a malicious or slow authoritative nameserver - to subvert the jostle logic designed to evict stalled queries, ultimately causing denial of resolution service. The jostle mechanism, which activates when the num-queries-per-thread limit is reached, is bypassed because retransmitted duplicate queries reset the aging timestamp to the latest duplicate rather than preserving the original query start time, preventing aged queries from being correctly identified and replaced. No public exploit has been identified at time of analysis; however, the vendor has confirmed the issue and released a patch in version 1.25.1.

CVE-2026-41136 Go MEDIUM PATCH GHSA This Month

Improper error handling in free5GC AMF prior to version 1.4.3 allows remote attackers to invoke the HTTPUEContextTransfer handler with uninitialized request objects by sending requests with unsupported Content-Type headers. The missing default case in the Content-Type switch statement silently skips deserialization without raising an error, resulting in integrity loss when malformed or crafted payloads reach the processor with null/uninitialized state. CVSS score of 5.5 reflects low integrity impact; publicly available exploit code exists (E:P).

CVE-2026-3344 MEDIUM This Month

WatchGuard Fireware OS contains a filesystem integrity bypass vulnerability in versions 12.0-12.11.7, 12.5.9-12.5.16, and 2025.1-2026.1.1 that allows authenticated attackers with high privileges to deploy malicious firmware updates and establish limited persistence on affected appliances. An attacker could circumvent security checks designed to validate firmware authenticity, though currently no patch is available.

CVE-2025-13940 MEDIUM This Month

An Expected Behavior Violation [CWE-440] vulnerability in WatchGuard Fireware OS may allow an attacker to bypass the Fireware OS boot time system integrity check and prevent the Firebox from shutting down in the event of a system integrity check failure. The on-demand system integrity check in the Fireware Web UI will correctly show a failed system integrity check message in the event of a failure.This issue affects Fireware OS: from 12.8.1 through 12.11.4, from 2025.1 through 2025.1.2.

CVE-2025-52953 MEDIUM PATCH This Month

An Expected Behavior Violation vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker sending a valid BGP UPDATE packet to cause a BGP session reset, resulting in a Denial of Service (DoS).  Continuous receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue affects iBGP and eBGP and both IPv4 and IPv6 are affected by this vulnerability. This issue affects Junos OS: * All versions before 21.2R3-S9, * from 21.4 before 21.4R3-S11, * from 22.2 before 22.2R3-S7, * from 22.4 before 22.4R3-S7, * from 23.2 before 23.2R2-S4, * from 23.4 before 23.4R2-S4, * from 24.2 before 24.2R2, * from 24.4 before 24.4R1-S3, 24.4R2 Junos OS Evolved: * All versions before 22.2R3-S7-EVO, * from 22.4-EVO before 22.4R3-S7-EVO, * from 23.2-EVO before 23.2R2-S4-EVO, * from 23.4-EVO before 23.4R2-S4-EVO, * from 24.2-EVO before 24.2R2-EVO, * from 24.4-EVO before 24.4R1-S3-EVO, 24.4R2-EVO.

CVE-2025-6211 PyPI MEDIUM POC PATCH This Month

A vulnerability in the DocugamiReader class of the run-llama/llama_index repository, up to version 0.12.28, involves the use of MD5 hashing to generate IDs for document chunks. This approach leads to hash collisions when structurally distinct chunks contain identical text, resulting in one chunk overwriting another. This can cause loss of semantically or legally important document content, breakage of parent-child chunk hierarchies, and inaccurate or hallucinated responses in AI outputs. The issue is resolved in version 0.3.1.
