CVE-2022-27258
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 · uneditedMultiple Cross-Site Scripting (XSS) vulnerabilities in Hubzilla 7.0.3 and earlier allows remote attacker to include arbitrary web script or HTML via the rpath parameter.
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 confidenceMultiple Cross-Site Scripting (XSS) vulnerabilities exist in Hubzilla 7.0.3 and earlier versions. The rpath parameter fails to properly sanitize user input, allowing remote attackers to inject arbitrary HTML or JavaScript code that executes in the context of other users' browsers.

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 Hubzilla versionLocate the installed Hubzilla version number, typically found in the admin panel under Site Information, in a version file within the application directory, or in a CHANGELOG/VERSION file at the root of the installationAffected if The installed version is 7.0.3 or any earlier version of Hubzilla
-
Verify rpath parameter is accessibleIdentify whether the application accepts and processes the rpath parameter in HTTP requests, typically through URL parameters or form inputs used for navigation or redirection purposesAffected if The rpath parameter is accepted and used by the application without sanitization
-
Inspect input handling for rpathExamine the application code or configuration that handles the rpath parameter to determine if user-supplied values are validated before being stored or displayedAffected if User input to rpath is not validated, filtered, or encoded before output
-
Test for reflected XSS in rpathSubmit a test payload containing HTML or JavaScript characters (such as <script>alert(1)</script>) as the rpath parameter value and observe if the payload is rendered unmodified in subsequent page outputAffected if The submitted rpath value appears in the response page without encoding or removal of script tags
You are affected if your Hubzilla installation is version 7.0.3 or earlier and the rpath parameter processes user input without proper sanitization, allowing injected script content to execute in other users browsers.

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 dataImplement proper input validation and output encoding on the rpath parameter and all user-supplied input throughout the application. Upgrade to a patched version of Hubzilla if available, or apply context-aware output encoding at every point where rpath data is rendered.
