André Baptista on X: "It's crazy how hallucinated AI CVE PoCs keep ending up in @NIST NVD references. One recent example is CVE-2026-21962, a 10.0 CVE in Oracle HTTP Server / Apache Proxy Plugin. https://t.co/u33KjhBxTZ links to a GitHub repository with a fake PoC. This also propagates to @github advisories: https://t.co/37TFXgGpe1 Meanwhile, some blue teams are injecting AI slop rules to prevent this and thinking they are protected, but they are not." / X
