Critical CVSS 9.6
CVE-2026-48334
Illustrator is affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- The application accepts input without checking it, opening the door to unintended behaviour.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
