Is JabRef Browser Extension safe?
JabRef Browser Extension fetches translator scripts from repo.zotero.org and executes them in active tabs without integrity checks.
When the extension initializes or encounters a translator cache miss, it downloads JavaScript code from repo.zotero.org and passes the raw response to an eval pipeline that executes the code in the current tab via browser.tabs.executeScript. No hash, HMAC, or signature validation is performed at any step, meaning a compromised or malicious response from repo.zotero.org would run arbitrary code in the context of whatever page the user has open.
