CVE-2026-48270
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPremiere Pro is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePremiere Pro contains an out-of-bounds write vulnerability during file parsing. A specially crafted malicious file can trigger the vulnerability, allowing an attacker to write data outside the bounds of allocated memory and potentially execute arbitrary code in the context of the current user.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Premiere Pro versionOpen Premiere Pro, go to Help > About Adobe Premiere Pro, or on Windows check Programs and Features, on macOS check Applications folder infoAffected if Version displayed is 25.x through 25.6.5, or 26.0 through 26.2.2
-
Compare version against affected rangesNote the full version number (such as 25.4.0 or 26.1.1) and manually compare: any version <= 25.6.5 OR between 26.0 and 26.2.2 inclusive is within the affected rangeAffected if Installed version falls within <= 25.6.5 OR 26.0 to 26.2.2
-
Verify file parsing is accessibleConfirm Premiere Pro can open media files (the built-in file import functionality used for video, audio, and project files)Affected if Premiere Pro is installed and functional, as the vulnerability triggers during normal file parsing operations
If the installed Premiere Pro version is 25.6.5 or lower, or between 26.0 and 26.2.2, the environment is vulnerable when processing untrusted media files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the official Adobe security update for Premiere Pro when available. Until then, exercise caution with untrusted media files and consider using application sandboxing or isolation for handling questionable content.
Premiere Pro 25.6.6 or later for 25.x branch; Premiere Pro 26.3 or later for 26.x branch
