LastPass, the online service that keeps your passwords safe behind one master password, is currently not nearly as secure as it should be.
According to Google's vulnerability researcher Tavis Ormandy, there's at least one unpatched vulnerability in LastPass that allows attackers to steal passwords "from any domain."

One security vulnerability, described in detail by Ormandy here, not only allows for an attacker to steal passwords, but -- in certain circumstances -- it can also be used to run arbitrary code on the victim's computer.
On Tuesday, LastPass announced that that particular issue has been resolved, but on Wednesday, the company acknowledged that there is an unpatched bug in its Firefox add-on.
The issue reported by Tavis Ormandy has been resolved. We will provide additional details on our blog soon.

Replying to a commenter to Tuesday's tweet, LastPass said that users needn't do anything at this point. However, the company still hasn't published anything on its official blog regarding these new security holes.
While no software is safe from security holes, vulnerabilities that affect password managers such as LastPass are particularly worrisome, as these services safeguard users' entire password collections. Especially when they come in droves, as they do these days.
This is not the first serious security issue LastPass has encountered. The service got hacked in 2011 and again in June 2015. And in 2013, a bug caused some users' Internet Explorer passwords to get exposed to the public.
UPDATE: March 22, 2017, 6:52 p.m. CET LastPass responded to our query by pointing us to their freshly published blog post, here. In the post, the company says it has worked with Ormandy to investigate and fix these vulnerabilities. The company claims it has fixed all issues now, and patches will be applied automatically for most users. According to LastPass, there is no indication that any of these vulnerabilities were exploited in the wild. The company vowed to provide a more comprehensive overview of these vulnerabilities, as well as its efforts to fix them and prevent further issues, in the future.
