The vulnerability was disclosed on May 13, 2025, and is classified as CWE-20 (Improper Input Validation). This security flaw could potentially lead to arbitrary code execution in the context of the current user (NVD, Wiz).

The vulnerability has been assigned a CVSS v3.1 Base Score of 9.1 (CRITICAL). The technical assessment indicates that the attack vector is network-based (AV:N), with low attack complexity (AC:L), requiring no privileges (PR:N) or user interaction (UI:N). The scope is unchanged (S:U), with high impacts on confidentiality (C:H) and integrity (I:H), but no impact on availability (A:N). The vulnerability has an Exploitation Probability Percentile (EPSS) of 86.3 and an Exploitation Probability of 3.2 (Wiz).

Successful exploitation of this vulnerability could allow a high-privileged attacker to bypass security mechanisms and execute arbitrary code in the context of the current user. Depending on the user's privileges, an attacker could potentially install programs, view, change, or delete data, or create new accounts with full user rights (Wiz).

Adobe has released security updates to address this vulnerability. Organizations are advised to apply the stable channel update immediately after appropriate testing.
