CVE-2023-46480
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 · uneditedAn issue in OwnCast v.0.1.1 allows a remote attacker to execute arbitrary code and obtain sensitive information via the authHost parameter of the indieauth function.
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 · high confidenceOwnCast v0.1.1 contains a critical vulnerability in the indieauth function where the authHost parameter is not properly validated or sanitized, allowing remote unauthenticated attackers to inject and execute arbitrary system commands and obtain sensitive information.

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.
-
Identify OwnCast versionRun 'owncast --version' or check the admin dashboard for the installed version numberAffected if The installed version is exactly 0.1.1
-
Locate indieauth configurationCheck for indieauth-related configuration files in the OwnCast data directory, typically under config/ or similar paths where OwnCast stores settingsAffected if Indieauth configuration files exist and the authHost parameter is present without proper validation
-
Verify indieauth feature statusCheck OwnCast admin panel or configuration to determine if the indieauth authentication feature is enabledAffected if Indieauth is enabled and the authHost parameter can be controlled via user input
-
Inspect network exposureCheck if the indieauth endpoints are exposed to unauthenticated network access by reviewing OwnCast web server logs and access patternsAffected if Indieauth endpoints are accessible without authentication from untrusted networks
A user is affected if they are running OwnCast version 0.1.1 with indieauth enabled and the authHost parameter is exposed to unauthenticated attackers.

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 dataUpgrade to a patched version of OwnCast; if unavailable, implement strict input validation and sanitization on the authHost parameter in the indieauth function, preferably using an allowlist approach for permitted hosts.
