Critical PHP flaws: update PHP on your WordPress site now Two critical PHP flaws disclosed on 21 October 2026 (CVE-2026-109618 and CVE-2026-109619) let an attacker run code on a server without logging in. Update to PHP 8.2.35, 8.3.36, 8.4.27 or 8.5.12. Here is how to check, how to update, and what to do if you can't yet. 
AI agent identity: knowing which agent is calling, and why that is only half the problem Agent identity is becoming solvable: signed requests, published key directories, authorisation mandates. A verified agent can still buy all your inventory, so identity is the foundation and not the answer. ChatGPT Atlas has been discontinued: what replaced it and what it means for your site OpenAI switched Atlas off on 9 August 2026, 292 days after launch. The browser is gone, the agentic traffic is not, and the replacements reach your site from different places. 
Perplexity Comet: what an agentic browser does to your site, and the court case about it Comet is free on every platform and its agent acts on sites for a real user. Amazon sued over exactly that, won an injunction, then lost it on appeal. The access question is now a live legal one. 
MCP security: the five ways agent tool access goes wrong MCP turns tool descriptions into model context, which makes the integration layer an attack surface. Tool poisoning, confused deputy, token passthrough, SSRF and rogue servers are the five that matter. x402 and agent payments: what a machine-payable endpoint means for your site x402 revives HTTP 402 so an agent can pay for a request in stablecoins and retry it. That turns abuse into a priced transaction, and it does not decide who is allowed to buy. llms.txt: we publish one, and no AI crawler has ever read it We have published an llms.txt since May 2026. Across four days of IP-verified logs, AI crawlers fetched our robots.txt 120 times and our sitemap 43 times. They fetched llms.txt zero times. Agentic browsers: your customer is now a robot, and that is fine An agentic browser is automation operated by a real customer. It fails every classic bot test and still deserves to reach your checkout. The answer is to require evidence of a human on particular steps, rather than to judge the client. OWASP API Security Top 10: which two a bot layer actually fixes Eight of the ten risks in the 2023 OWASP API Security Top 10 are authorization and inventory bugs only your own code can fix. API4 and API6 are the two where a bot-protection layer is the right tool. 
Why Do Bots Fill Out Forms? The Economics of Form Spam and How to Stop It Why do bots fill out forms?

What is WAAP? Web Application and API Protection explained WAAP means Web Application and API Protection: a WAF, DDoS mitigation, bot management and API protection sold as one cloud service. The bot component is the one to scrutinise, because it needs signals a network vendor has no reason to collect. 
Gartner and bot management: the Magic Quadrant that does not exist There is no Gartner Magic Quadrant for bot management. There is one for Cloud WAAP, and bot mitigation is a criterion inside it. Where each vendor appears, and how to read the two analyst views together. OWASP automated threats: the 21 names your vendor should be using The OWASP Automated Threat Handbook gives every bot attack a vendor-neutral name and an OAT number. The full taxonomy, the five that cost the most money, and how to use it in an RFP. Web Bot Auth: signed agents solve identity, not intent Web Bot Auth lets an AI agent cryptographically sign its requests so you can verify who it is. That fixes user-agent spoofing and leaves the harder question untouched: a verified agent can still be doing something you do not want.
