CyberRota Analysis
AI-GeneratedGrist versions prior to 1.7.15 are vulnerable to cross-site scripting (XSS) due to insufficient escaping of user-controlled values in server-rendered pages, allowing attackers to inject malicious scripts. This vulnerability can lead to unauthorized access and manipulation of documents, enabling a document editor to escalate their privileges to owner-level access. Organizations using Grist should prioritize this update to mitigate the risk of data breaches and unauthorized changes to document settings.

Original NVD Description
Grist is spreadsheet software using Python as its formula language. Prior to 1.7.15, several server-rendered Grist pages embedded user-controlled values into the page and into inline scripts without fully escaping them, allowing cross-site scripting. On the main application page, a document's name or description, set by a document editor, is rendered into the page that other users load when opening the document. On the OAuth2 end-of-flow page, the openerOrigin request parameter was reflected back into the served page. Injected script runs in the victim's Grist origin and can act through the authenticated session, reading or modifying data and changing sharing settings and access rules. A document editor could therefore escalate to owner-level access. This issue is fixed in version 1.7.15.
