CVE-2026-46529

A flaw was found in Atril, Evince and Xreader. A malicious link inside a specially crafted PDF document can cause arbitrary code execution when clicked due to improper quoting of attacker-controlled PDF link-destination fields during remote go-to (/GoToR) actions. This issue allows an attacker to execute arbitrary code with the privileges of the user that clicked on the embedded link.

To exploit this issue, an attacker needs to convince a user to open a specially crafted PDF document and to click on a malicious link inside the document, limiting its exposure. Also, this flaw allows an attacker to execute arbitrary code with the privileges of the user that clicked on the embedded link, which is usually a low-privileged user account, limiting its impact. However, an attacker can package a single file that is simultaneously a valid PDF document and a valid ELF shared library, making the exploit self-contained and exploitable via a single click. Due to these reasons, this vulnerability has been rated with an important severity.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this vulnerability, do not click on links inside PDF documents from untrusted or unverified sources.
