The last week has seen a flurry of severe and critical software vulnerabilities affecting thousands of major sites and sending people into a panic. What’s going on here, and what can we do about it? The bugs If we want to understand what’s going on in the world of software security at the moment, we need to understand what’s going on with all these bugs. I’m not a cybersecurity expert, so I’m going to link to external explanations instead of going into the gory technical details myself as these people are always going to do a better job at that. PHP2Shell – CVE-2026-109618 and CVE-2026-109619 (a.k.a. “the big one in the news”) Two different security teams, one from California security company Calif (as part of OpenAI’s “Patch the Planet” program) and another from Israeli-U.S. cloud security company Wiz (they’re part of Google Cloud, apparently), both found these two Remote Code Execution (RCE) bugs in PHP. They were both using frontier AI models (a.k.a. LLMs, specifically GPT-5.6 Sol/Gemini 4 Argon) to find these vulnerabilities and build the exploits. Interestingly, one of the bugs (CVE-2026-109618) was found by a security audit the PHP Foundation did in 2024 (funded by the Sovereign Tech Agency which is coincidentally one of the most interesting things happening in the open source space at the moment) but they basically ignored it because they had bigger concerns and couldn’t agree on a fix. The reasoning behind it was that no-one could really figure out how to create an actual exploit based on the theoretical issue. One thing LLMs are very good at is taking a theoretical security vulnerability, even if that vulnerability is a vague description of what the issue could be, and building it into a full exploit. This has become a major issue in recent months as any notice of a security patch will immediately result in people pointing their LLMs at the codebase, whereupon the agents can very quickly read through diffs until they find something that looks like a security patch, then go backwards to the vulnerability it covers, and follow this all the way to an exploit. This happens so fast, in fact, that at this point I think it is a reasonable that the moment you announce a security patch should be taken as a last possible date that the full exploit is not being publicly or privately distributed. This PHP2Shell (as it’s being marketed, vulnerabilities seem to come bundled with their own marketing departments now) is estimated to affect upwards of 70% of the …
