DescriptionCVE.org

Acrobat Reader is affected by an Untrusted Search Path vulnerability that could result in privilege escalation. An attacker with high privileges could leverage this vulnerability to gain elevated access. Exploit depends on conditions beyond the attacker's control. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

AnalysisAI

Untrusted Search Path exploitation in Adobe Acrobat and Acrobat Reader allows a local attacker who already holds high privileges to gain unauthorized read access to sensitive confidential data under specific, attacker-uncontrollable environmental conditions. Affected products include Acrobat 2024 (≤24.001.30383), Acrobat Reader, and Adobe Acrobat (both ≤26.002.21900), per EUVD-2026-74105 and Adobe advisory APSB26-141. …

Vulnerability AssessmentAI

Exploitation Exploitation requires all of the following simultaneously: (1) the attacker already holds high privileges on the local system (PR:H - this is not an unauthenticated or low-privilege attack vector); (2) specific environmental conditions beyond the attacker's direct control must be satisfied, such as a particular Acrobat installation state, a writable directory present in the DLL search order, or an OS-level filesystem configuration (AC:H); (3) a victim must actively open a malicious file within the vulnerable Acrobat application (UI:R - passive or drive-by exploitation is not possible); and (4) the entire attack is strictly local (AV:L - remote exploitation is not possible without a separate initial-access mechanism). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Real-world risk is moderate-to-low despite the 'privilege escalation' label in the description. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the patch described in Adobe security bulletin APSB26-141 at https://helpx.adobe.com/security/products/acrobat/apsb26-141.html. … Detailed patch versions, workarounds, and compensating controls in full report.
