Cisco Identity Services Engine RADIUS Denial of Service Vulnerability

Cisco patched a RADIUS flaw in Identity Services Engine letting unauthenticated remote attackers trigger denial of service on ISE nodes.

A vulnerability in the RADIUS feature of Cisco Identity Services Engine allows an unauthenticated remote attacker to cause a denial of service by sending crafted RADIUS requests directly to an affected device. The flaw stems from improper handling of certain RADIUS requests and can render ISE nodes unavailable. In single-node deployments, endpoints that have not yet authenticated would be unable to access the network until the node recovers. Cisco has released software updates addressing the issue.

LiteLLM Flaws Let Attackers Execute Code as Root and Steal Cloud Credentials

Wiz disclosed LiteLLM flaws including CVE-2026-59822 MCP auth bypass, now in CISA KEV, enabling root RCE and AWS credential theft from exposed gateways.

Wiz researchers disclosed weaknesses in the open-source LiteLLM AI gateway: CVE-2026-59821 allows authenticated administrators to execute code as root via the Custom Code Guardrails feature, while CVE-2026-59822 is an MCP authentication bypass where a meaningless Bearer token establishes a valid session. The MCP bypass was observed in the wild through Wiz honeypots and added to CISA's Known Exploited Vulnerabilities catalog on September 2. A scan of 3,074 internet-facing instances found 294 (9.6%) accepting the default master key sk-1234 or lacking authentication. Fixes shipped in LiteLLM 1.82.0 (guardrail hardening) and 1.84.0 (MCP bypass); exposed instances can leak provider API keys and temporary AWS IAM credentials via the pass-through feature and metadata service, with a related config-check issue tracked as CVE-2026-35029.

Attackers actively exploit two CVSS 9.8 auth bypasses (CVE-2026-61979, CVE-2026-15981) in the miniOrange SAML WordPress plugin, forging SAML responses to become admin.

CVE-2026-61979 is a SAML algorithm confusion flaw that lets attackers sign forged assertions using the identity provider's RSA public key as an HMAC secret; CVE-2026-15981 stems from PHP treating openssl_verify()'s -1 error return as true, allowing a crafted signature that triggers an OpenSSL error to validate. Both bugs independently let unauthenticated attackers obtain WordPress administrator sessions and both are confirmed exploited in the wild.

VU#889462: Casdoor authentication server is vulnerable to authorization bypass

Casdoor IAM versions 3.115.0 and earlier allow organization admins to bypass tenant isolation through inconsistent authorization checks, tracked as CVE-2026-15630.

CERT/CC published VU#889462 describing an authorization bypass in Casdoor, an open-source access management platform, affecting versions 3.115.0 and earlier. The flaw (CVE-2026-15630) stems from controllers ignoring the ?id= query parameter used for authorization decisions and acting on JSON body fields instead, letting a single-organization administrator perform unauthorized administrative actions against arbitrary organizations in multi-tenant deployments. Impact can escalate to complete tenant-isolation compromise and potential compromise of the entire Casdoor instance, including SSO/SAML disruption. No vendor patch is available because researchers could not reach Casdoor; mitigations include least privilege, MFA for admin accounts, and alerting on cross-organization administrative activity.

CVE-2026-50522: Microsoft SharePoint Server RCE Vulnerability

CVE-2026-50522 is an unauthenticated .NET deserialization RCE in SharePoint Server Subscription, 2019, and 2016; Microsoft patched it July 14, 2026.

CVE-2026-50522 (CWE-502) lets unauthenticated attackers send crafted serialized .NET payloads to network-accessible SharePoint endpoints, triggering gadget-chain deserialization and remote code execution under the privileged SharePoint service account. It affects SharePoint Server Subscription Edition, SharePoint Server 2019, and SharePoint Server 2016 Enterprise; Microsoft published the advisory on July 14, 2026. The EPSS score is 20.346%, but no public PoC exists and the flaw is not in CISA's KEV catalog at publication. Mitigations include applying Microsoft updates, rotating SharePoint machine keys, enabling AMSI, and restricting internet exposure.

One runaway AI agent racked up a $50,000 cloud bill

Mandiant's AI Risk and Resilience report details prompt injection, AI supply chain compromises, agent abuse, and a runaway agent that accrued $50,000 in cloud charges.

Mandiant, drawing on Google Threat Intelligence Group (GTIG) observations, warns that poisoned data sources, model dependencies, and extension hooks can turn AI agents into channels for reconnaissance, lateral movement, and sandbox escape. Mandiant responded to incidents involving UNC6780 (TeamPCP), who stole AI service credentials and used prompt injection against AI coding assistants, while GTIG disclosed the first confirmed criminal use of an AI-developed zero-day exploit in a planned mass exploitation campaign. Red team tests showed an AI assistant manipulated into cloning internal repositories to an external GitHub account, and a runaway accounting agent made over 15,000 costly API calls in under an hour, generating roughly $50,000 in cloud charges.

Critical ArangoDB Flaws Allow Authentication Bypass and Remote Code Execution as Root

Two critical ArangoDB flaws (CVSS 9.8 and 9.9) enable unauthenticated API access and root code execution; fixes shipped in version 3.12.11

Remedio researchers found two ArangoDB flaws: GHSA-rrgq-978q-36mq (CVSS 9.8), an authentication bypass caused by the server inconsistently interpreting URL-encoded '/_api' paths, and GHSA-rvhw-4hpw-9vrx (CVSS 9.9), which lets users with database write access run JavaScript tasks with root privileges via the isSystem flag. Chained, they allow administrative database access without credentials, theft of the root password hash, and root code execution, exposing files such as /etc/shadow, TLS keys and cluster signing material on the official container image. ArangoDB shipped fixes in version 3.12.11 on August 31, 2026, with advisories published September 6; CVE identifiers were still pending. Users on 3.12.10.1 or earlier should upgrade, restrict exposure and rotate potentially exposed credentials.

Exploits in the Wild for Citrix ADC and Citrix Gateway Directory Traversal Vulnerability CVE-2019

Unit 42 confirmed in-the-wild exploitation of CVE-2019-19781, a critical Citrix ADC/Gateway directory traversal flaw enabling unauthenticated file access and RCE.

CVE-2019-19781, a CVSS 9.8 directory traversal vulnerability, affects all supported versions of Citrix ADC and Citrix Gateway. Unit 42 captured multiple exploitation attempts in the wild and identified scanning activity from roughly 700 Shodan-exposed hosts. The flaw stems from improper pathname handling in Apache, allowing unauthenticated attackers to read sensitive files like smb.conf or achieve remote code execution via crafted XML. Palo Alto Networks released Threat Prevention signatures 57497 and 57570 on January 7, 2020, while Citrix published advisories CTX267027 and CTX267679 with responder policy mitigations pending a late-January patch.
