Adobe Premiere Pro: Out-of-bounds write allows code execution
Summary
Adobe Premiere Pro versions 26.5.2 and earlier and 25.6.6 and earlier on Windows and macOS contain an out-of-bounds write vulnerability (CWE-787). If a user opens a malicious project or media file, an attacker can execute arbitrary code with the rights of the current user. The attack is local and requires user interaction, but no privileges.
Affected
- Adobe Premiere Pro 26.5.2 and earlier (Windows and macOS)
- Adobe Premiere Pro 25.6.6 and earlier (Windows and macOS)
Fixed in
- 26.x line: 26.5.3 (per CVE record and Adobe bulletin APSB26-101)
- 25.x line: 27.0 (per CVE record; verify in APSB26-101, as the 25.x fixed build is not confirmed independently)
Workaround
Unknown. No vendor workaround published.
- Do not open project or media files from untrusted sources until patched.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in this update.
- No public proof-of-concept found in research; CISA SSVC lists exploitation as none.
- Adobe rates the update priority 3.
Our recommendation
- Inventory all Premiere Pro installations and their versions.
- Update to the fixed build for your version line once confirmed in APSB26-101.
- Handle project and media files from external sources, such as freelancers or clients, with care until patched.
- Run Premiere Pro under standard user accounts, not local administrator accounts.
