Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution

IdentifiersCVE-2026-47914CWE-416· Use After Free

CVE-2026-47914 is a use-after-free vulnerability in Adobe Acrobat Reader DC affecting versions 24.001.30365, 26.001.21651, and earlier. The flaw exists in the handling of Annotation objects, where the software fails to validate the continued existence of an object before performing operations on it, leading to a stale pointer dereference. A remote attacker can trigger the condition by inducing the target to open a malicious file or, per supporting context, visit a malicious page. Successful exploitation can result in arbitrary code execution in the context of the current user/process.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary code execution in the context of the current user. Given the published CVSS 3.1 vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H and score 7.8, impact includes potential full compromise of confidentiality, integrity, and availability of data accessible to that user account, including installation of malware, modification of local data, and process-level takeover of Acrobat Reader.

Mitigation

If you can’t patch tonight, do this now.

No vendor workaround is noted beyond patching. Until updates are fully deployed, reduce exposure by preventing users from opening untrusted PDF or other attacker-supplied files, restricting access to malicious or untrusted web content that could deliver exploit content, and using endpoint controls such as application isolation, attachment sandboxing, and least-privilege user contexts to limit post-exploitation impact.

Remediation

Patch, then assume compromise.

Apply Adobe's security update referenced in bulletin APSB26-63. Upgrade Adobe Acrobat Reader DC to a version newer than 24.001.30365 and 26.001.21651, as those versions and earlier are affected. Standard remediation is to deploy the vendor-fixed release across all supported endpoints running Acrobat Reader.
