CVE-2025-54271
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 · uneditedCreative Cloud Desktop versions 6.7.0.278 and earlier are affected by a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability that could lead to arbitrary file system write. A low-privileged attacker could exploit the timing between the check and use of a resource, potentially allowing unauthorized modifications to files. Exploitation of this issue does not require user interaction.
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.
