Memory disclosure via out-of-bounds read
Published May 12, 2026 · Updated May 12, 2026
Out-of-bounds read in Adobe Illustrator 2025 29.8.6 and earlier and 2026 30.3 and earlier allows attackers to disclose memory. Adobe has not disclosed the affected parser or the bounds-checking operation that reads beyond the intended memory boundary. Exploitation requires a user to open a malicious file; the documented consequence is sensitive-memory disclosure without integrity or availability impact.
