- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
NCSC-NL published an advisory summarizing three vulnerabilities patched by Adobe in Illustrator, all related to file-handling mechanisms. CVE-2026-75990 involves incorrect authorization allowing arbitrary code execution when a user opens a malicious file. CVE-2026-75991 relates to improper input validation, also enabling code execution via specially crafted files. CVE-2026-75992 is an out-of-bounds write that occurs during processing of certain file input, allowing memory corruption and arbitrary code execution when a malicious file is opened.
All three vulnerabilities require user interaction (opening a crafted file) and carry high CVSS v3 scores (8.6, 8.6, and 7.8 respectively), indicating significant impact but not remote/network exploitation without user action. No in-the-wild exploitation is mentioned in the advisory. Defenders should prioritize applying Adobe's released updates for Illustrator and exercise caution with untrusted Illustrator files, particularly in workflows where files are received from external sources (e.g., design agencies, print vendors, freelance contributors).

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
