CVE-2026-3690 Apr 11, 00:17 npm HIGH PATCH This Week

Unauthenticated remote attackers bypass authentication in OpenClaw canvas endpoints due to improper authentication implementation (CWE-291). Exploitation requires no user interaction and yields high confidentiality/integrity impact. Network-accessible attack vector with high complexity (CVSS:3.0 7.4 AV:N/AC:H/PR:N). No public exploit identified at time of analysis. Originally reported as ZDI-CAN-29311.

CVE-2026-4252 Mar 16, 16:32 HIGH POC This Week

A critical authentication bypass vulnerability exists in Tenda AC8 router firmware version 16.03.50.11 where the IPv6 handler function check_is_ipv6 relies on IP address for authentication, allowing remote attackers to gain unauthorized access. The vulnerability has a publicly available proof-of-concept exploit on GitHub and scores 9.8 CVSS, enabling complete compromise of the affected device with no authentication required. While not currently listed in CISA KEV, the combination of public exploit availability and ease of exploitation makes this a high-priority vulnerability for organizations using affected Tenda routers.

CVE-2026-86485 Sep 07, 16:26 LOW PATCH Monitor

IP spoofing via forged HTTP headers in JetBrains YouTrack before 2026.2.18634 allows unauthenticated remote attackers to bypass Bitbucket webhook source validation, causing YouTrack to process attacker-crafted webhook payloads as if they originated from a legitimate Bitbucket server. The root cause is CWE-291 - reliance on IP address for authentication - specifically trusting client-controlled headers such as X-Forwarded-For to gate webhook acceptance. No public exploit has been identified at time of analysis, and JetBrains has released a patched build.
