CVE-2023-7114
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMattermost version 2.10.0 and earlier fails to sanitize deeplink paths, which allows an attacker to perform CSRF attacks against the server.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMattermost versions 2.10.0 and earlier do not properly sanitize deeplink paths, enabling attackers to craft malicious URLs that can trigger cross-site request forgery (CSRF) attacks against authenticated users on the server.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Mattermost server versionAccess the Mattermost System Console > About page, or query the API endpoint /api/v4/system/ping, or check the version file if present in the installation directoryAffected if The installed version is 2.10.0 or earlier (versions below 2.10.1)
-
Verify deeplink functionality is in useCheck if the server handles incoming deeplink URLs (typically URLs with custom schemes or paths used for mobile app deep linking). Inspect server logs for deeplink-related requests or check if the deeplink feature is explicitly enabled in configurationAffected if Deeplink handling is enabled and the server processes deeplink paths from URLs
-
Confirm CSRF token enforcement for state-changing operationsReview the application's session and request handling configuration. Check if anti-CSRF tokens (such as CSRF cookies or headers) are required for POST, PUT, DELETE requests. This may be visible in the server configuration or by inspecting HTTP responses for CSRF token presenceAffected if Anti-CSRF tokens are not implemented or are not validated for requests originating from deeplink paths
The environment is affected if Mattermost version is 2.10.0 or earlier AND deeplink paths are processed without proper sanitization and CSRF protection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data2.10.1
Upgrade to a version later than 2.10.0 and implement proper path sanitization for deeplinks along with anti-CSRF tokens for state-changing operations.
