🔒 Cloudflare disclosed multiple HTTP/1.x request smuggling vulnerabilities in the open-source Pingora framework (CVE-2026-2833, CVE-2026-2835, CVE-2026-2836) that can desynchronize proxy and backend request framing when Pingora is used as an ingress proxy. The issues — reported by Rajat Raghav via Cloudflare’s bug bounty — allow bypass of proxy-layer checks, cross-user hijacking, or cache poisoning in exposed standalone deployments. Cloudflare confirmed its CDN and customer traffic were not affected and released fixes and hardening in Pingora 0.8.0. If you run Pingora as a proxy, upgrade to 0.8.0 as soon as possible.

⚠️ CISA has added three vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2021-22054 (Omnissa Workspace ONE SSRF), CVE-2025-26399 (SolarWinds Web Help Desk insecure deserialization), and CVE-2026-1603 (Ivanti Endpoint Manager authentication bypass). BOD 22-01 requires Federal Civilian Executive Branch agencies to remediate listed KEV entries by the specified deadlines. CISA strongly urges all organizations to prioritize timely patching and mitigation to reduce exposure to active exploitation.

🔍 Anthropic reported discovering 22 new vulnerabilities in the Firefox browser using Claude Opus 4.6 during a two-week assessment in January 2026. Fourteen issues were rated high, seven moderate and one low, and most were patched in Firefox 148. The model detected a JavaScript use-after-free bug in about 20 minutes, which researchers validated in a virtualized environment. When tasked to produce exploits the model succeeded only twice after many attempts and roughly $4,000 in API spend, underscoring that discovery is cheaper than reliable exploitation.

⚠️ Researchers at Imperva disclosed a configuration weakness in the OAuth credential handling of n8n that fails to sanitize the authorization URL, enabling a stored XSS payload to be saved in the application database. An attacker with access to a victim's n8n instance can replace a legitimate URL with malicious JavaScript that executes when other users interact with the same credential. Because the payload is persistent, it can expose multiple OAuth credentials and enable broader system compromise. The flaw was fixed in n8n v2.6.4 on February 6.

🔒 CISA added two critical vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog affecting Hikvision and Rockwell Automation. CVE-2017-7921 (CVSS 9.8) is an improper authentication flaw that can enable privilege escalation and exposure of sensitive information in multiple Hikvision products. CVE-2021-22681 (CVSS 9.8) involves insufficiently protected credentials in Studio 5000 Logix Designer, RSLogix 5000 and Logix Controllers, which can allow an unauthorized network user to bypass verification and modify controller configuration or application code. SANS has detected exploit attempts targeting vulnerable Hikvision cameras; there are no public reports of active attacks exploiting the Rockwell issue. Federal civilian agencies are required to update to supported software by March 26, 2026 under BOD 22-01, and CISA urges all organizations to prioritize remediation of KEV-listed vulnerabilities.

⚠️ A critical vulnerability in the User Registration & Membership WordPress plugin (CVE-2026-1492, CVSS 9.8) is being actively exploited to create unauthenticated administrator accounts. The flaw allows attackers to supply a role during membership registration and obtain full admin privileges. Defiant's Wordfence blocked over 200 exploit attempts in the past 24 hours, indicating live attacks. WPEverest released a fix in 5.1.3 (the article notes 5.1.4 was released last week); update immediately or disable the plugin until you can patch.

🚨 Cisco released its March 4 semiannual firewall update addressing 25 security advisories and 48 CVEs, led by two “perfect 10” flaws in Secure Firewall Management Center (FMC).
