Premiere Pro: Out-of-bounds write allows arbitrary code execution
Summary
An out-of-bounds write flaw (CWE-787) in Adobe Premiere Pro can be abused to run arbitrary code with the rights of the logged-in user. The attacker needs a victim to open a malicious project or media file, so there is no network attack path. Adobe reports no exploitation in the wild, and the CVSS base score is 7.8 (high).
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
- Adobe Premiere Pro 26.5.3 for the 26.x line (CVE record and bulletin)
- Adobe Premiere Pro 27.0 for the 25.x line according to the CVE record; the bulletin lists 27.0 as the updated version, but the fixed build for 25.x is not confirmed in the sources. Check APSB26-101 before assuming 25.x is safe.
Workaround
- No vendor workaround is documented. Unknown.
- Until patched, do not open untrusted or unexpected project and media files in Premiere Pro. This stopgap comes from a third-party tracker, not from Adobe.
- Keep creative workstations on standard user accounts to limit the impact of code execution.
Exploitation
- Not known to be exploited in the wild.
- The Zero Day Initiative lists exploitation as "No" for the Premiere bulletin.
- CISA SSVC assessment: exploitation none, not automatable.
- No public proof of concept found in the sources checked.
Our recommendation
- Inventory all Premiere Pro installations and their versions, including the 25.x line.
- Update to 26.5.3 or 27.0 through Creative Cloud. For 25.x, confirm the fixed build in APSB26-101 first.
- Until patched, restrict opening files from untrusted sources and keep users on standard accounts.
- Monitor for exploitation reports and public proof-of-concept code.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
