Descrição resumida

Langflow contains a code injection vulnerability that allows unauthenticated attackers to achieve full remote code execution on default Langflow deployments.

Ação necessária

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Descrição técnica

IBM Langflow OSS 1.0.0 through 1.10.0 allows unauthenticated attackers to chain /api/v1/auto_login (mints SUPERUSER tokens to any network caller) with /api/v1/validate/code (executes user code via exec()) to achieve full RCE on default Langflow deployments

——0FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to 1.11.2, sofia_handle_sip_i_refer() placed raw Refer-To URI parameters and headers inside a sip_invite_params channel-variable block passed to switch_ivr_originate(). The originate parser treated a comma in the attacker-controlled value as a variable separator, allowing an authenticated caller on a bridged call to inject arbitrary variables into a newly originated leg. An injected execute_on_originate value could invoke the system dialplan application before answer and execute operating-system commands with the FreeSWITCH process privileges. SIP REFER is enabled by default, and the sender needs only a registered account and a call that takes the off-box transfer path, not administrative or Event Socket access. This issue is fixed in version 1.11.2.4h CVE-2026-100358—

——0SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the Studio Dropdown Editor passes $dropdown_name through html_entity_decode() and writes the result verbatim into a PHP language file under custom/ that is included on later page loads. An administrator can inject persistent PHP that executes as the web-server account, survives cache clears, and compromises application and host confidentiality, integrity, and availability. This issue is fixed in versions 7.15.2 and 8.10.2.5h CVE-2026-541419.0 CRÍ

——0OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before 0.57.13, a remote direct message received through a configured Yuanbao channel is converted into a generic channel AgentTurnRequest that uses the default tool policy without establishing an interactive approval context. Under the default Supervised autonomy policy with Node enabled, node_exec is classified as a write operation that should prompt for approval, but ApprovalGate treats missing APPROVAL_CHAT_CONTEXT as a non-interactive turn and allows execution. Because Yuanbao direct messages are open by default, an external sender who can message the connected bot can influence the agent to execute JavaScript and operating-system commands as the OpenHuman user without an approval prompt. The issue requires a configured Yuanbao channel, the default approval-requiring policy state, Node availability, and successful model selection of node_exec. This issue is fixed in version 0.57.13.7h CVE-2026-68524—

——0An unauthenticated attacker can exploit temporary-file handling, access an open file descriptor, and inject a "file:" URI to cause OFBiz to load an attacker-controlled Screen definition. This issue affects Apache OFBiz: before 24.09.08. Users are recommended to upgrade to version 24.09.08, which fixes the issue.9h CVE-2026-835429.8 CRÍ

——0Improper Control of Generation of Code ('Code Injection') in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to execute arbitrary code on the server by staging crafted widget XML in a multipart upload and overriding the mainDecoratorLocation used by a manager login route through an anonymous JSON request, causing OFBiz to load the staged XML through its live screen descriptor mechanism and evaluate an unsandboxed Groovy expression while rendering the authentication-failure page. Further validation established the following: -- The exploit does not require a malformed or incomplete multipart body: a well-formed multipart request that is kept in flight and then allowed to complete normally is sufficient. -- The screen loader reads the widget XML from a live process file descriptor while the upload is streaming, rather than from any file the attacker persists to disk. -- The same underlying issue is also reachable through the public, explicitly unauthenticated /sfa/control/editPortalPageColumnWidth route, returning command output directly in an HTTP 200 response — it is not limited to the login-failure rendering path used in the original report. Users are recommended to upgrade to version 24.09.08, which fixes this issue.8h CVE-2026-829608.8 ALT

——0Improper Control of Generation of Code ('Code Injection') in ModelFormField in the Apache OFBiz cms plugin before 24.09.08 on all platforms allows a remote authenticated attacker holding only CMS content-editor access to execute arbitrary operating system commands as the OFBiz process user via a single HTTP POST request, by submitting a crafted caContentIdTo parameter to EditAddContent, because the CMS screen copies that parameter into a top-level context variable that is interpolated into a form field's use-when attribute and the resulting string is passed unvalidated to GroovyUtil.eval(), whose compile-time SecureASTCustomizer sandbox does not restrict runtime reflection, allowing a payload that closes the expanded string literal and invokes java.lang.Runtime via reflection. Users are recommended to upgrade to version 24.09.08, which fixes this issue.8h
