——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 1.11.2.6h CVE-2026-1030205.3 MÉD

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the webroot admin.php multisite administration page is enabled without an authentication check, reads database configuration from sqlconf.php, and connects to each configured site database. An unauthenticated network actor can obtain site identifiers, database names, site names, exact OpenEMR versions and patch levels, pending upgrade status, and direct login and patient-portal links. This issue is fixed in version 8.3.0.6h CVE-2026-1232088.8 ALT

——0noname Electron desktop build v1.11.2 through v1.11.6.1 contains an unauthenticated local file server with wildcard CORS that allows malicious websites to read, overwrite, or delete installation files. Attackers can send cross-origin requests to /writeFile on localhost port 8089 to overwrite renderer scripts, executing JavaScript with Node.js access as the local user.7h CVE-2026-1232063.7 BAI

——0EdgeChat before 2.20.3 contains a missing authentication vulnerability in the GET /files/:key route that allows unauthenticated or banned users to download decrypted public-channel attachments because canAccessFile() accepts a null user id. Attackers holding an attachment object key can omit or supply an invalid token to retrieve plaintext attachments without a session or channel membership.7h 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 8.10.2.7h 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 0.57.13.9h
