CVE-2026-104983
MediumCVSS 6.3Summary
In Linux Mint Xreader up to 4.6.9, the function g_file_get_child in shell/ev-window.c (PDF Attachment Saving Handler) is vulnerable to path traversal via manipulation of the attachment argument. The attack can be performed remotely and the exploit has been publicly disclosed.
Risk Assessment
A remote attacker could exploit path traversal to write files outside the intended directory, potentially leading to data overwrite or disclosure.
Recommendation
Update Xreader to a version later than 4.6.9 or apply a workaround; monitor public exploits and restrict access to the attachment saving feature.
Other vulnerabilities in Linux Mint Xreader
Original NVD description (English source)
A vulnerability has been found in Linux Mint Xreader up to 4.6.9. Impacted is the function g_file_get_child of the file shell/ev-window.c of the component PDF Attachment Saving Handler. Such manipulation of the argument attachment leads to path traversal. The attack may be performed from remote. The exploit has been disclosed to the public and may be used. One of the project maintainers closed this issue as "completed", because "EPUB support was removed from Xreader and reimplemented in Xepub". Code analysis indicates that this might be a misunderstanding of the situation.
