Acrobat Reader is affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to disclose sensitive information. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AnalysisAI
Out-of-bounds read (CWE-125) in Adobe Acrobat and Acrobat Reader - versions up to 26.002.21900 and Acrobat 2024 up to 24.001.30383 - allows disclosure of sensitive process memory when a victim opens a specially crafted document file. The confidentiality impact is rated high (C:H), meaning leaked memory contents could include pointers, session data, or other in-process secrets, though there is no integrity or availability impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim to actively open a specially crafted malicious document in Adobe Acrobat or Acrobat Reader running an affected version (≤26.002.21900 for the main product line, or ≤24.001.30383 for Acrobat 2024). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.5 (Medium) appropriately reflects the constrained threat model: local file-delivery vector (AV:L), low complexity (AC:L), no privileges required (PR:N), but mandatory user interaction (UI:R), with impact limited exclusively to confidentiality (C:H/I:N/A:N). … 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 | Adobe has published security bulletin APSB26-141 at https://helpx.adobe.com/security/products/acrobat/apsb26-141.html; users should consult that advisory directly for the confirmed patched release versions and apply the available update to all installed Acrobat and Acrobat Reader instances. … Detailed patch versions, workarounds, and compensating controls in full report. |
