Hi @psuc,
sorry for all the trouble that is causing this.
First and foremost: You do not need an alternative to TablePress. TablePress, your site, and your server are safe.
I don’t know if you read through all my reples in that other thread. It explains why I feel that this is invalid, and that TablePress does nothing wrong here. Other users agree with that.
The alleged “vulnerability” can only affect people that have a site that was already compromised by an attacker, and that explicitly activate a dangerous feature in Excel on their computer, and that then explicitly ignore two very clear security warnings from Excel. And even then, the attacker (after already having hacked a site!) would have far easier attack vectors in other WordPress features.
Wordfence does agree that this is a very, very low risk and that websites are safe. However, their company policy is that they will still mark this as “critical” and recommend to delete a plugin, which they do for all vulnerability reports. I quote: “It’s just indicating that there is a security vulnerability present which we always deem a critical issue regardless of the vulnerability’s severity.” The “critical” here does in no way relate to the severity of the issue, which is actually “very low”.
And yes, I do blame the CSV program here, which by the way the security teams of Google, Twitter, and phpMyAdmin also do. So claiming this to be a “security risk based on industry standards” is at least debatable.
However, I’m currently testing a security enhancement that will filter out potentially dangerous formulas when exporting a table to a CSV file, without affecting legitimate formula use. This will be shipping with TablePress 2.0-RC2, likely available today or tomorrow at https://tablepress.org/8-million-downloads-tablepress-2-0/. Wordfence has agreed that such a change will allow them mark the issue as resolved in their scans.
Even though TablePress is doing nothing wrong, it doesn’t hurt to further protect people that, maybe unknowingly, do dangerous things on their computer without being aware of the implications.
To summarize: TablePress, your site, and server are safe. Regardless, an enhancement in TablePress 2.0 will make careless users safer.
Best wishes,
Tobias
