CVE-2026-27626— OliveTin 操作系统命令注入漏洞

OliveTin vulnerable to OS Command Injection via `password` argument type and webhook JSON extraction bypasses shell safety checks

OliveTin gives access to predefined shell commands from a web interface. In versions up to and including 3000.10.0, OliveTin's shell mode safety check (`checkShellArgumentSafety`) blocks several dangerous argument types but not `password`. A user supplying a `password`-typed argument can inject shell metacharacters that execute arbitrary OS commands. A second independent vector allows unauthenticated RCE via webhook-extracted JSON values that skip type safety checks entirely before reaching `sh -c`. When exploiting vector 1, any authenticated user (registration enabled by default, `authType: none` by default) can execute arbitrary OS commands on the OliveTin host with the permissions of the OliveTin process. When exploiting vector 2, an unauthenticated attacker can achieve the same if the instance receives webhooks from external sources, which is a primary OliveTin use case. When an attacker exploits both vectors, this results in unauthenticated RCE on any OliveTin instance using Shell mode with webhook-triggered actions. As of time of publication, a patched version is not available.

OliveTin 操作系统命令注入漏洞

OliveTin是OliveTin开源的一个Web应用。 OliveTin 3000.10.0及之前版本存在操作系统命令注入漏洞，该漏洞源于shell模式安全检查不足，可能导致未经验证的远程代码执行。
