It complements the first control of 22 October 2026, which focused on the Node.js runtime, and does not replace it.\r\n\r\nWhy a second control\r\n\r\nCVE-2026-111497 is an out-of-bounds write in the Google Brotli decoder, the library that decompresses Brotli (\"br\") data. It was first published as a Node.js vulnerability, because Node.js bundles this decoder. Later publications showed that the flaw is in the library itself. Every product that embeds an affected version of the decoder is concerned, whatever its language or vendor. A public proof of concept demonstrates code execution.\r\n\r\nAny server that decompresses request bodies sent with \"Content-Encoding: br\" exposes the decoder to unauthenticated attackers. Known cases include Express 5 and NestJS 11 on Node.js, Koa and Fastify setups, Bun, Envoy and Istio with request decompression enabled, and any application or reverse proxy that decodes Brotli request bodies with an affected library.\r\n\r\nThe flaw also works in the other direction. A malicious server can compromise an unpatched client that decodes a Brotli response, for example Node.js fetch(), Python clients (requests, httpx, aiohttp, Scrapy) with the Brotli or brotlicffi package, or libcurl builds with Brotli support.\r\n\r\nWhat this control checks\r\n\r\nPatrowl sends small, valid Brotli-compressed requests to each asset and observes whether the server decodes them. The check does not depend on the technology: it detects the behaviour, whatever the stack behind it. These requests are what any legitimate client could send. They never reach the vulnerable code path and cannot affect the availability of the service.\r\n\r\nHow to read the result\r\n\r\nPotentially impacted means the asset decodes Brotli request bodies: the attack surface is exposed. It does not confirm that the asset is vulnerable. The version of the Brotli decoder in use is not visible from the outside.\r\n\r\nThis check covers applications that parse request bodies on their root path. A Not impacted result does not rule out exposure on other routes, nor on the client side.

If an update is not possible right away, reject requests with \"Content-Encoding: br\" at the reverse proxy or WAF.\r\n\r\nWhen the asset is hosted on a managed platform or behind a CDN (for example Platform.sh, Upsun or Fastly), the decoding may be done by the provider's edge router, in front of your application. You cannot patch it yourself, but this router handles all the traffic of your site. Ask your provider to confirm that its edge components are patched against CVE-2026-111497. Assets hosted on a managed platform or behind a CDN carry the tag \"paas: platform.sh\" or \"cdn: fastly\" in the asset view: for these assets, the Brotli decoding is done by the provider's edge router, in front of your application, and only the provider can patch it.\r\n\r\nAffected and fixed versions\r\n\r\nGoogle Brotli 1.0.3 to 1.2.0 are affected, fixed in 1.0.10, 1.1.1 and 1.2.1.
