Critical XXE Clusterfuck: Apache Tika Gets Slammed with CVE-2025-66516

Oh wonderful, another “critical as fuck” vulnerability to brighten up everyone’s miserable existence. This time, our lucky winner is Apache Tika – that oh-so-helpful toolkit for content detection and file analysis. Turns out, the bloody thing has been swallowing external XML entities like a drunken intern clicking random links. The delightful folks at security land gave it a whopping CVSS score of 10.0 — because of course it’s a total shitstorm.

So what’s the problem? Some absolute genius managed to find an XXE (XML External Entity) vulnerability that lets an attacker pry open your system like a tin of spam. You know, that cute little flaw where XML parsing decides to trust external data sources because “what could possibly go wrong?” Well, if you’re running this pile of digital duct tape, expect your system files to end up in some hacker’s data zoo. And yes, this little gem affects *all* versions before the patch, because apparently we love living dangerously.

The Apache team has now dumped out a patch faster than a panicking intern realizing they hit “Reply All.” So if you’ve got Tika running anywhere — and if you don’t know, that’s even worse — you better patch the crap out of it right now. Otherwise, don’t come crying when some basement-dwelling cyber-goblin starts rifling through your sensitive documents.

Moral of the story? Never trust XML. Hell, never trust *anything*. Everything’s on fire, everything’s broken, and if something’s “secure,” that just means no one’s looked at it yet.

For those masochistic enough to read the full horror show, here’s your link to doom:

Reminds me of the time I watched a junior admin “fix an XML error” by giving a parser root access and write permissions everywhere. It worked great — right up until the server screamed, caught fire, and started emailing everyone’s SSH keys to HR. Kids these days, I swear.
