FortiGuard Center Outbreak Alerts

FortiGuard Labs has observed attack activity targeting CVE-2026-85706, a critical path traversal vulnerability in GitLab Community Edition and Enterprise Edition. The vulnerability affects the repository commits API and can allow an unauthenticated remote attacker to read arbitrary files from a vulnerable GitLab server due to improper path confinement and missing authentication enforcement. The vulnerability carries a CVSS score of 10.0 and requires no privileges or user interaction. CVE-2026-85706 was added to the CISA Known Exploited Vulnerabilities catalog on September 11, 2026. Public exploit and proof-of-concept material has also emerged, increasing the potential for exploitation against exposed, unpatched GitLab instances.

Attackers are actively targeting Orkes Conductor servers vulnerable to CVE-2026-58138, a critical unauthenticated remote code execution vulnerability in its GraalVM script evaluators. FortiGuard telemetry is observing active attack attempts targeting vulnerable Orkes Conductor deployments. The vulnerability allows an unauthenticated attacker to submit a malicious workflow definition containing JavaScript or Python expressions to the Conductor workflow API. Because vulnerable evaluators can be configured with unrestricted host access, the attacker can escape the intended scripting environment and execute arbitrary operating system commands with the privileges of the Conductor process. Public proof-of-concept exploit code is available, including a working exploit targeting Conductor v3.23.0. Exploit material has also been published through Exploit-DB, increasing the likelihood of opportunistic scanning and exploitation of exposed deployments.

FortiGuard Labs has uncovered a long-running supply chain compromise targeting QuickFox, a Windows VPN/network acceleration application primarily used by overseas Chinese users. Attackers tampered with official Windows installers to deploy a custom backdoor tracked as FDMTP, enabling selective victim profiling and post-compromise access. The campaign has reportedly been active since August 2025 before being publicly disclosed in August 2026.

FortiGuard Labs continues to detect exploitation attempts targeting the WP2Shell attack chain (CVE-2026-63030 and CVE-2026-60137), a critical unauthenticated remote code execution (RCE) vulnerability affecting WordPress Core. Telemetry collected over the past seven days shows the highest volume of blocked attacks originating from or targeting Poland, Australia, Japan, the United States, and Turkey.

Attackers are actively exploiting a PAN-OS GlobalProtect authentication bypass vulnerability to gain unauthorized VPN access to exposed Palo Alto Networks firewalls. An attacker who successfully exploits CVE-2026-0257 can: – Establish unauthorized VPN sessions through affected GlobalProtect gateways. – Bypass authentication controls without valid user credentials. – Gain network-level access typically reserved for authenticated VPN users. – Potentially facilitate further reconnaissance, lateral movement, or follow-on attacks within the victim environment.

FortiGuard Labs continues to observe active exploitation of CVE-2026-48908, a critical unauthenticated remote code execution vulnerability affecting the JoomShaper SP Page Builder extension for Joomla. At the time of release, FortiGuard telemetry recorded 1,210 blocked exploitation attempts in the last 24 hours and 15,626 attempts over the past 7 days.

FortiGuard Labs continues to observe exploitation attempts targeting CVE-2026-10520 following the public release of technical details and proof-of-concept (PoC) exploit code. At the time of publication, FortiGuard telemetry recorded 886 blocked attempts in the last 24 hours and 8,406 over the past 7 days, with weekly activity increasing by 82%. The Technology, Automotive, Banking/Finance/Insurance, and Education sectors remain among the most targeted.

FortiGuard Labs has observed a significant uptick in attacks targeting Langflow, leveraging a recently discovered authentication bypass vulnerability that allows unauthenticated remote attackers to fully compromise affected servers.

Security researchers have disclosed a new denial-of-service (DoS) attack technique dubbed HTTP/2 Bomb, tracked as CVE-2026-49975, that affects multiple major HTTP/2 server implementations. Unlike traditional volumetric DDoS attacks, HTTP/2 Bomb does not require a large botnet. Researchers demonstrated that a single attacker operating from a modest internet connection can generate sufficient resource exhaustion to disrupt vulnerable servers.

Exploitation activity targeting vulnerable Citrix NetScaler ADC and Gateway appliances remains persistent and widespread, with FortiGuard Labs telemetry continuously observing attack attempts from global sources probing exposed NetScaler SAML endpoints for vulnerable configurations. Analysis from FortiGuard IPS sensors shows sustained targeting of internet-facing NetScaler deployments configured as SAML Identity Providers (IdP). Attackers continue using malformed authentication requests to exploit the memory overread condition associated with CVE-2026-3055, potentially exposing sensitive session data, authentication tokens, and credential material.
