IBM Langflow versions 1.0.0 through 1.10.0 contain a vulnerability allowing remote code execution due to incomplete validation of MCP server configuration files. An attacker who can supply or modify an MCP server config could execute arbitrary code on the Langflow host, fully compromising the agent runtime and any connected tools or data.

Langflow, an open-source framework used to build AI agent workflows, contains a server-side request forgery vulnerability caused by weak default configuration and incomplete SSRF protections. An attacker could exploit this to make the Langflow server issue unauthorized requests to internal or cloud-metadata endpoints, potentially exposing sensitive infrastructure or credentials. This is a genuine, credibly documented vulnerability (CVSS 7.7) rather than a speculative or low-quality report.

IBM Langflow, an open-source visual builder for AI agent workflows, contains a path traversal flaw where a malicious flow can fetch attacker-controlled content and write it to arbitrary paths on the server via a crafted Content-Disposition header. An authenticated attacker can abuse this to overwrite configuration, code, or scheduled/startup files, likely leading to full compromise of the Langflow instance. This is a serious framework-level vulnerability requiring only low-privilege authenticated access.

A vulnerability in IBM Langflow's Python Interpreter component allows an authenticated user to execute arbitrary commands with elevated privileges due to improper input validation. This affects Langflow OSS versions 1.0.0 through 1.10.1, and could allow an attacker with low-level access to escalate privileges and take control of the underlying system. Given the CVSS score of 8.8, this is a serious flaw that requires prompt patching.

IBM Langflow OSS versions 1.0.0 through 1.10.1 expose a public flow build endpoint that allows unauthenticated remote code execution due to an incomplete security denylist. Attackers can construct flows using code-execution-capable agent components (OpenDsStarAgent, CodeActAgentSmolagents, CSVAgent) that are not blocked by the validation function, achieving arbitrary code execution without any authentication.

Microsoft released patches for at least 570 security vulnerabilities in its July 2026 Patch Tuesday, nearly triple the prior month's record-setting release. Microsoft attributes the surge in discovered flaws to AI-assisted vulnerability research, signaling both increased attacker and defender use of AI tooling to find bugs at scale. Organizations face a substantially expanded patching burden across Windows and related Microsoft products.

Researchers at Checkmarx identified seven malicious npm packages targeting the Vite frontend tooling ecosystem, codenamed ViteVenom, which deliver a remote access trojan (RAT). The campaign extends the previously observed ChainVeil operation, leveraging a four-tier blockchain-based command-and-control infrastructure spanning multiple chains including Tron to evade takedown and detection.

A previously undisclosed OpenSSL flaw dubbed HollowByte allows an attacker to send an 11-byte crafted TLS request that forces an unpatched server to allocate up to 131 KB of memory for a message fragment that never completes, permanently consuming that memory on glibc-based systems until the process is restarted. OpenSSL silently patched the issue in June without issuing a CVE, advisory, or changelog entry, and Okta's Red Team later identified, named, and disclosed the bug.

A critical unauthenticated remote code execution vulnerability, dubbed wp2shell, was discovered in WordPress core affecting versions 6.9 and 7.0, exploitable via a single anonymous HTTP request even on default installs with no plugins. WordPress released patched versions 6.9.5 and 7.0.2 and pushed forced auto-updates to mitigate mass exploitation. Researcher Adam Kues of Assetnote (Searchlight Cyber) discovered and reported the flaw.

Ernst & Young (EY) disclosed a data breach stemming from the compromise of a third-party support ticket system used by its IT staff. The incident highlights ongoing risks associated with vendor and supply-chain access to sensitive internal support infrastructure. Details on the scope of data accessed and the threat actor responsible remain limited based on available reporting.

HollowByte is a denial-of-service vulnerability in OpenSSL that allows unauthenticated remote attackers to exhaust server memory using a malicious 11-byte payload. The flaw affects any service exposing an OpenSSL-based TLS listener, potentially causing crashes or severe resource exhaustion with minimal attacker effort.

Abbott Laboratories is investigating two separate cybersecurity incidents: unauthorized access to legacy Exact Sciences systems within its Cancer Diagnostics business, and a separate extortion claim involving alleged theft of data from its LabCentral portal. Both incidents are under active investigation and details on scope, data types affected, and threat actor identity remain limited.

A high-severity denial-of-service vulnerability (CVE-2026-9653) affects Rockwell Automation 1756-EN2, 1756-EN3, and 1756-ENBT communication modules due to improper validation of CIP Implicit Connection packets. A network-based attacker can send crafted packets to repeatedly disrupt device connections, though connections recover automatically. Rockwell Automation has released patches for the EN2 and EN3 modules, while the ENBT module is discontinued and will not receive a fix.

A stored cross-site scripting (XSS) vulnerability affects Rockwell Automation FactoryTalk DataMosaix Private Cloud versions 8.02 and earlier, allowing an authenticated high-privilege attacker to inject persistent malicious scripts via the Workflows configuration. Successful exploitation could lead to account takeover, credential theft, or redirection of other users to malicious sites when they access the affected page. No public exploitation has been reported to date.

Three vulnerabilities (CVE-2025-12011, CVE-2025-12012, CVE-2025-11698) affect multiple Rockwell Automation Logix controller families, allowing an unauthenticated remote attacker to send an invalid project or malformed file data that triggers a classic buffer overflow, causing the device to enter a major non-recoverable fault (MNRF). Exploitation results in denial-of-service impacting industrial control processes rather than data confidentiality or integrity loss. No known public exploitation has been reported to CISA at this time.

The Bricksforge WordPress plugin (versions up to 3.1.8.6) contains a critical privilege escalation flaw in its Pro Forms registration action. Improper validation of the fieldIds parameter allows unauthenticated attackers to whitelist arbitrary form fields, including the administrator role field, enabling full site takeover via crafted registration requests.

Yamcs, an open-source mission control framework, contains a vulnerability in its authentication endpoint that allows unlimited password-guessing attempts due to missing rate limiting and account lockout mechanisms. An unauthenticated remote attacker could exploit this to brute-force credentials for any user account. The issue is patched in versions 5.12.7 and 5.13.0.

CVE-2026-56453 affects HCL DFXAnalytics, allowing a remote attacker to intercept and manipulate HTTP responses to bypass authentication or authorization controls. This can result in unauthorized access to targeted user accounts without requiring credential theft.

Open WebUI versions prior to 0.3.14 contain a CORS misconfiguration (allow_origins=*) combined with authenticated cookie-based requests to the /api/v1/functions endpoint, enabling attacker-controlled websites to trigger arbitrary code execution on the server. Exploitation requires an authenticated admin to visit a malicious webpage, after which the attacker can silently deploy or modify server-side functions to achieve RCE. This poses a serious risk to any organization self-hosting Open WebUI as an interface for LLMs or agentic workflows.

Open WebUI versions prior to 0.9.5 contain a stored cross-site scripting vulnerability in the OAuth 'picture' claim handling, where MIME type validation relies on file extension instead of Content-Type headers. This allows attackers to smuggle malicious SVG files that execute script content when rendered, enabling authentication token theft and account takeover of Open WebUI users.
