Critical Grist-Core Vulnerability: Because Apparently Even Spreadsheets Wanna Kill You Now

Well, some bright spark discovered that Grist-Core — that open-source spreadsheet thing used by teams pretending they know how to manage data — has a bloody Remote Code Execution (RCE) flaw. Yep, that’s right, folks. Someone figured out how to turn a damn spreadsheet formula into a full-blown system compromise. Because who *doesn’t* dream of getting pwned by a cell full of math symbols and equal signs?

So the issue lies in the way Grist processes formula inputs. Apparently, the system was naive enough to let users shove arbitrary code through formulas. Hackers — being the resourceful little bastards they are — realized they could slip malicious payloads in there, have the server obediently run them, and basically take over the whole goddamn thing. Lovely. Just what infrastructure needs — spreadsheet-driven chaos.

The engineers at Grist have since patched the hole (finally), releasing updates that neuter this particular insanity. And of course, they’re “advising users to upgrade immediately” — which, translated from dev-speak, means “we have no clue how many of you idiots ignored the last update, but we’re begging you to fix your shit before someone mines crypto on your servers.”

Moral of the story: stop treating production tools like toys, keep your damn software up-to-date, and maybe, just maybe, think twice before putting formulas you copy from Stack Overflow straight into your precious business spreadsheets. Otherwise, your next quarterly report might just come with a side of ransomware.

Reminds me of the time some genius clicked “Enable Macros” on an Excel file from “Sexy_Invoice_Final_v3.xlsm” — and then wondered why the accounting server started belching spam about crypto investments in Russian. Same shit, different spreadsheet.
