Adobe Photoshop: Out-of-bounds read in Photoshop Desktop
Summary
Adobe Photoshop Desktop on Windows and macOS contains an out-of-bounds read vulnerability (CWE-125) that can lead to disclosure of sensitive memory contents. An attacker can exploit it by convincing a victim to open a malicious file, which requires user interaction. The vulnerability affects Photoshop 2026 up to version 27.11 and Photoshop 2025 up to version 26.11.8, and Adobe reports no known exploitation in the wild.
Affected
- Adobe Photoshop 2026: 27.11 and earlier (Windows and macOS)
- Adobe Photoshop 2025: 26.11.8 and earlier (Windows and macOS)
Fixed in
- Adobe Photoshop 2026: 27.11.1 or later
- Adobe Photoshop 2027: 28.0 or later
- Adobe Photoshop 2025: no fix, as it will not receive further updates
Workaround
Unknown.
- No vendor-documented workaround. Until patched, treat PSD and other image files from unknown or untrusted sources as suspect.
Exploitation
- Adobe is not aware of any exploits in the wild.
- Third-party trackers list it as not known to be exploited.
- Not listed in CISA KEV according to Strix.
- Public proof of concept: none found.
Our recommendation
- Update all Photoshop installations via the Creative Cloud desktop app to 27.11.1 or 28.0.
- Identify Photoshop 2025 installations and migrate them to Photoshop 2026 27.11.1 or Photoshop 2027 28.0, as they will not receive fixes.
- Apply a policy to open files only from trusted sources, especially email attachments and downloads.
- Do not defer this update, as it also fixes other Photoshop issues in the same bulletin.
