New Router Vulnerability 'WPSplinter' Affects Millions of Devices
A Belgian security researcher has uncovered a critical vulnerability in Broadcom's Wi-Fi implementation, dubbed 'WPSplinter'. The flaw, which is actually two separate bugs, allows attackers within Wi-Fi range to execute arbitrary code on affected routers via a crafted WPS message. Broadcom has stated the issue was known since 2010 and was supposedly fixed in 2018, but the patch was insufficient. The vulnerability potentially affects millions of devices from numerous router manufacturers that use Broadcom's Wi-Fi software. The researcher has published a list of affected devices on GitHub and has contacted Broadcom and Belgian authorities. No responses have been received yet, and no public fix is currently available.
The article highlights a widespread security vulnerability in Broadcom-based routers, which are fundamental to internet connectivity for many households and businesses. While not directly an AdTech story, the vulnerability could impact the infrastructure that supports digital advertising delivery, but the direct relevance is limited.

Critical Cisco Bug Exploited Since 2023, Global Alert Issued
Cisco disclosed a critical vulnerability (CVSS 10.0) in its Catalyst SD‑WAN product family that allows remote attackers to gain full, persistent privileged access to affected devices. Cisco’s researchers found evidence of exploitation dating back to 2023, and some impacted organizations are described as critical infrastructure. Governments including Australia, Canada, New Zealand, the United Kingdom and the United States issued warnings; U.S. agency CISA ordered civilian federal agencies to patch by the end of the specified Friday citing imminent threat. Cisco and governments did not publicly attribute the attacks to a named threat actor, though Cisco tracked a cluster of activity as UAT‑8616. The disclosure follows a December advisory for another actively exploited Cisco vulnerability in Async software.
Hackers Exploit Recently Patched WordPress Flaws
Security researchers and multiple cybersecurity firms warn that attackers are actively exploiting two recently patched critical WordPress vulnerabilities (affecting versions 6.9.0–6.9.4 and 7.0.0–7.0.1). WordPress pushed immediate and, where possible, forced updates after the fixes were released. Firms including Patchstack, Hexastrike, and WatchTowr reported in-the-wild exploitation. Researcher Daniel Card sampled ~4,200 sites and estimates under 15% remain vulnerable, which could extrapolate to roughly 90 million at-risk WordPress sites. The exploit chain includes a vulnerability dubbed WP2Shell, reported by Adam Kues of Searchlight Cyber. Cloudflare and web application firewalls have helped block some attacks while many sites remain exposed.
Cisco patches CVSS 10.0 Secure Workload authentication bypass
Cisco released emergency patches addressing a maximum-severity authentication-bypass vulnerability in its Secure Workload platform (tracked as CVE-2026-20223) that earned a CVSS 10.0 score. The flaw allows unauthenticated remote attackers to gain Site Admin privileges by sending specially crafted requests to Secure Workload's REST API, bypassing authentication. The vulnerability affects both SaaS-hosted and on-premises deployments, can enable cross-tenant access to sensitive telemetry and configuration, and has no known workaround — Cisco recommends applying the fixes immediately. Security publishers noted this is one of several 'perfect 10' bugs disclosed for Cisco in 2026 and emphasized the broad impact on enterprises that use Secure Workload as part of zero-trust and micro-segmentation architectures.
