Adobe Premiere: Out-of-bounds write allows arbitrary code execution
Summary
Adobe Premiere contains an out-of-bounds write vulnerability (CWE-787) that can be triggered by opening a malicious file. A successful attacker could execute arbitrary code in the context of the current user, which could expose the user's files and credentials. Exploitation requires that a user opens the malicious file, so the attack vector is local.
Affected
- Adobe Premiere 26.5.2 and earlier (Windows and macOS)
- Adobe Premiere 25.6.6 and earlier (Windows and macOS)
Fixed in
- Adobe Premiere 26.5.3 (Windows and macOS)
- Adobe Premiere 27.0 (Windows and macOS)
Workaround
Unknown. No vendor workaround is documented. Until the update is installed, do not open project files or media from untrusted sources.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues addressed in bulletin APSB26-101.
- Public proof of concept: Unknown.
- Vendor priority rating: 3.
Our recommendation
- Update Adobe Premiere to version 26.5.3 or 27.0, or a later build.
- Check the installed Premiere versions across all workstations, especially those of marketing, media and content teams.
- Until patching is complete, avoid opening email attachments, downloaded footage or project files from unknown or external sources.
- Monitor Adobe security bulletins for updates.
