Adobe Premiere Pro: Buffer overflow allows code execution via malicious file
Summary
A buffer overflow in Adobe Premiere Pro can be abused to execute arbitrary code with the rights of the current user. A local attacker with low privileges can exploit it if a victim opens a malicious file, such as a project or media file delivered by email or a shared drive. Exploitation depends on conditions outside the attacker's control. Adobe reports no known exploits in the wild.
Affected
- Adobe Premiere 26.5.2 and earlier (26.x branch), Windows and macOS
- Adobe Premiere 25.6.6 and earlier (25.x branch), Windows and macOS
Fixed in
- Adobe Premiere 26.5.3 for the 26.x branch
- Adobe Premiere 27.0 for the 25.6.x branch
Workaround
Unknown. No vendor-documented mitigation is available. Until the update is installed, do not open project or media files from untrusted sources.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in bulletin APSB26-101.
- OffSeq lists the vulnerability as not known to be exploited.
- CISA SSVC: exploitation none, not automatable, total technical impact.
- No public proof of concept was found in the research.
Our recommendation
- Install Adobe Premiere 26.5.3 or 27.0 (or later) on all Windows and macOS systems, as Adobe bulletin APSB26-101 covers 11 issues in one update.
- Until patched, only open project and media files from trusted sources.
- Run Premiere with standard user rights, not local administrator rights.
- Note: the CVSS score is disputed (6.7 in the CVE record, 7.8 in the bulletin text for the same vector). Verify the live bulletin and use the higher score for prioritisation until resolved.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
