Tiny Tiny RSS before 829d478f is vulnerable to XSS window.opener attack

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 confidence

Tiny Tiny RSS before commit 829d478f contains a Cross-Site Scripting vulnerability via the window.opener object. When the application opens external links in new browser tabs or windows, the opened page can potentially manipulate the originating page through window.opener, allowing script execution in the context of the trusted Tiny Tiny RSS site.

MitigationAdd rel="noopener noreferrer" attribute to all links that open new browser windows/tabs, or use window.open() with the noopener feature set, to prevent the opened page from accessing the originating window object.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Tiny Tiny RSS version
    Check the version.php file in the tt-rss root directory, or run `git log --oneline -1` if using git
    Affected if The installed version is before commit 829d478f or the version cannot be determined to be at/after that commit
  2. Check for rel=noopener noreferrer in link code
    Search the codebase for external link generation: look for patterns like 'window.open' or anchor tags pointing to external URLs in files such as functions.php, view.php, or plugin files
    Affected if External links opened via window.open() or anchor tags lack the noopener and noreferrer rel attributes
  3. Inspect headline/external link handling
    Examine the code that handles displaying headlines or excerpts with external links - typically in lib/xmlphp.php or similar rendering files - to verify if link() or similar helper functions include rel="noopener noreferrer"
    Affected if The code that generates external links in headlines, excerpts, or user-generated content does not add rel="noopener noreferrer" attributes
  4. Verify link rendering in affected views
    View the HTML source of pages containing external links (such as the headline view or any feed content with external URLs) and inspect anchor tags for target="_blank" to confirm they include rel="noopener noreferrer"
    Affected if Links that open in new tabs (target=_blank) are missing the rel="noopener noreferrer" attribute in the rendered HTML

You are affected if your Tiny Tiny RSS installation is before commit 829d478f AND external links in the application are missing rel="noopener noreferrer" attributes on links that open in new browser tabs.
