27 Oct 2026 Google Brotli Memory corruption
A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream. Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1.

About the KEV Catalogue
What is the CISA KEV catalogue?
CISA's list of flaws attackers are known to be using. A flaw is added only with reliable evidence of attacks and a known fix.
Why does it matter more than the CVSS score?
Few CVEs are ever used in attacks. These are, so fix them first, whatever their score.
What is the due date?
The deadline for US federal agencies to fix it (BOD 26-04, which replaced BOD 22-01): as little as three days for recent entries. A sensible deadline for anyone.
Does it apply outside the US?
The deadlines don't, but the flaws are in software used everywhere. If you run it, it applies to you.
What does "used in ransomware" mean?
CISA knows ransomware groups have used the flaw.
How often is it updated?
CISA adds flaws several times a week. CVE Hawk checks hourly and alerts you within half an hour if it's your software.
