CVE-2026-33949 Details
Description
Tina is a headless content management system. Prior to version 2.2.2, a path traversal vulnerability in @tinacms/graphql allows unauthenticated users to write and overwrite arbitrary files within the project root. This is achieved by manipulating the relativePath parameter in GraphQL mutations. The impact includes the ability to replace critical server configuration files and potentially execute arbitrary commands by sabotaging build script. This issue has been patched in version 2.2.2.
A path traversal vulnerability has been identified in TinaCMS versions prior to 2.2.2, specifically within the @tinacms/graphql package. This vulnerability allows unauthenticated users to write and overwrite arbitrary files in the project root by manipulating the relativePath parameter in GraphQL mutations. The issue arises from the path validation logic, which fails to properly recognize backslashes as directory separators on non-Windows platforms. Exploiting this vulnerability could lead to the replacement of critical server configuration files and potentially allow for the execution of arbitrary commands by disrupting build scripts.
Users are advised to update TinaCMS to version 2.2.2 or later, where this vulnerability has been patched.
